Air-entrained materials as shape-able materials and pre-shaped objects are in use since prehistoric times. These continue to be used for supporting the body or limbs in various positions such sleeping, reclining or sitting. These materials and shapes allow better flow of body fluids, heat conservation, dissipation and absorption of the reverse impacts and vibrations.

In ancient times, bedding materials were of vegetative origins like grasses and leaves. The materials retained the body moisture causing putrefaction, so required frequent replacement. Another reason for frequent replacement was that all ‘beds’ get infested with lice. It was difficult to terminate the lice-infections, so bedding stuffs were occasionally burnt.

Unknown visitors and guests brought in infections and smells. The problem was acute at Inns, Sarais and Brothels. In dwellings, such visitors were asked to sleep in hay lofts. The hay stocks were seasonally replaced, the hay floor was ‘re-done’ or the bedding hay was frequently smoked or sun-dried. The vegetative materials were mixed with rice husks (fairly stable material) and eucalyptus or other aromatic leaves, to act as the natural insecticide. The ‘floored sleeping arrangements were prone to rodents, insects or snakes. The lower sections close to the floor, were affected by cold draughts in winters.

Winters in Northern Europe are too severe for spending nights in hay lofts. Guests shared with the family and servants, the warmth of kitchen-fire side platforms. These platforms were multipurpose facilities, used for food preparation, dining and social interactions. Privacy was not a medieval consideration. Loose straws of hay in kitchen area were fire-hazard, and so not preferred. Instead chopped grass, hay, straw, chaff, or bird feathers were stuffed into sacks or burlap bags. Such bags, the manageable stock served as the raw mattress for centuries. Where woven fabrics were difficult to get, the chopped fillers were contained in bottomless, four-sided frames, or open boxes. The chopped hay in heaps, bags or boxes were sometimes topped with leather, pieces of tapestry, wool or heavy quilted fabrics.

Straw vs Hay
Hay vs Straw Hay is harvested while a live, healthy plant. Straw is the dead stalks of plants after the valuable upper parts of the plants have been harvested. Hay is valuable as provides better nutrition to animals while straw provides little nutrition and so often burnt. Straw has sharp edge and can hurt anyone handling or eating it. Other farm or agriculture products have some value include chaff, husk etc. There value was as stuffing material in mattresses. due to finer size and non rotting nature. Chopped Straw is used as an additive for mud walls, whereas chaff and husk are added to brick muds. These were also used as floor spread for stables, poultry farms.

Questions have been raised, which came first the Mattress or Pillow? No find of historical, archeological or narratorial evidence supports the ‘mattress’ as the inevitable form of sleeping. Japan, China, India and many other countries of the region have used ‘head-supportas the required tool for sleeping. Even today, travelers, fakirs, beggars, and road side squatters, may not use a mattress, but use the elbow for supporting the head. The head supports were through the raised head-bar of Charpais (India), wood pieces carved to shape of head, own entwined hair, Pagari (Indian head gear as head-tied or loosened form), bundled piece of tapestry or travel bag and stuffed pillows.

Long houses of primitive age had two types of sleeping facilities, parallel and perpendicular to the central aisle or fires. For sleeping solidly built or leg supported platforms were created, often supplemented with ‘bunks’ at upper level. The legged platforms had strips of wood or woven mats with piece of raised wood as the head support. Many regions in South Asia have been using Manch or Manchi (a wood platform covered with woven mat), often taller than the height of the crop.

Buckwheat pillows were once very popular and still admired by many, except for the crushing sounds during head shifting. Main stuffing material were of buckwheat hull shells. These are durable and fairly long lasting. The pillows originally came from Japan. Buckwheat controls the temperature.

Pillow shells or bags are made of woven fabrics, leather, mats, etc. The shells or bags are stuffed, and so naturally contour to the shape of the head. Feather bags or pillows sag fast, making the mass stiff. In case of a puncture the feathers spread out, and it is difficult to restuff. Other stuffing materials include, cotton, wool, coconut. Kapok (silk-cotton -Ceiba Pendandra) fibers.

The stuffed mattresses or pillows (and perhaps some form of bolsters) had some common problems such as uneven sagging, loss firmness, hygiene, unmanageable high volume and consequent heavy weight.

A k’ang is a platform bed with a stove built underneath. It was used for different purposes through the day. Starting around 300 AD, pipes or flutes were introduced to distribute the heat and ventilate the smoke from stove. Spread of palm fronds or mat was sufficient as the bedding surface.

4 ILLUMINATION and COLOUR SHADES -Issues of Design 37

1 Charles Courtney Curran Paris at nnight in Gas Lights 1889

26 Oskar Mulley Bozen bei Nacht 1918

Illumination manifests directly and through reflections, but always with the shadows. The shadows define the source of illumination, intensity, extent and direction. In art, illumination and shadows get expressed as depths of the elements and as cast shadows. Shadows could be intense occluding the colour, surface texture and minor details, or could be thin enough to reveal the form and surface underneath. The opacity and translucency of the shadows, both are expressed through colour combinations of hues, tones, tints and shades. These mixed in various proportions create effects of realism, grandiose, expressionistic, impressionistic and illusions.

15 Direct and Reflected Illumination in a Cave

For a long time, light was only seen as a functional element of everyday life. The first artists’ who realized the importance of light were the primitive age cave painters. They recognized two omni present sources of light, 1 from the mouth of the cave and 2 interior ‘reflector’ surfaces (which, were favourably angled, of lighter colour and not heavily textured). Both were dependent on solar illumination. The third sources of illuminations were the hand-held oil lamps. These were used to draw the artwork and later perhaps for the ceremonial exposure that included the narration. The illumination was stationary as well as moving. The stationary light was to highlight relevant elements in the scene whereas, the moving illumination was to interconnect the sections for reinforcing the magic or narration.

All three types of illuminations affected the art compositions (scale, distances between the elements, white spaces, direction, movement by orientation of the head, colour intensity and the texture). These were subtle and informal lessons. The lessons were used in other expressions and communications. The effects of illumination had two classes. The variable effects were due to the changing position of the sun, shifting of the observer and intensity of the illumination. The stationary effects relied on the referential consequences such as through occlusion, masking, framing, etc.

The primitive age wall-art did not use shadowing for forming the depth aspect of the individual objects, for presenting the overlapping of objects, or for indicating the day, night, ground or skies. At places, the lower body sections of animals, though have lighter colours, pointing to the lighter skin area.

Bronze Age lasted from roughly 3300 to 1200 BC with main centers that formed adjacent domains, such as Sumer, Mesopotamia, Greece and Egypt. These were also connected to many other civilizations. In these cultures, two main types of drawn arts developed, the wall art and figures on potteries. In both the cases, the figures were highlighted without the ‘in-fill shadows’ or ‘fall-out shadows’, but with through the stark contrast with the background and in few cases emphatic outlines or silhouette lines. In early periods, the wall-arts or ceramics had the background space sometimes filled with non-overlapping human figures at smaller scale, but never used motifs, vegetation or architectural features.

Through this period, four types of representative arts emerged. Drawn arts like Paintings, Ceramics and Mosaics had human or animal figures in 2D format, but no vegetation, terrain details or built-forms as main or background. Body adornments and sculptures had the advantage, the base forms were already 3D formed, and so any painting on these had greater depth. The Mycenaean, Greeks, Egyptian, Romans and others in Asia, painted their sculptures, but, without exploring the natural (sun-light) shadows at the place, however sometimes enhancing the 3D effect of the forms through dark-light colour variations.

8 Fragment of Mycenaean Pictoral Style krater, boxers, 1300–12500 BC

To cause wider colour variations between the illuminated and shadowed areas wider palette was required. The really variegated range was available in oxide colours like red, umber, sienna, etc., through selective sourcing from nature and by calcining (sintering, as raw versus burnt) the minerals. Shadows in drawn arts require a wider palette. It came about in Europe with disintegration of the Roman Empire and Migrations of the Barbarians.

11 Macedonian tomb fresco from Agios Athanasios, Thessaloniki, Greece, 4th century BC.

In absence of shadowing, the emphases in composition were achieved through larger scaling, use of inlays, embellishments, incised (low engraving in wet clay). The low incision was also used in early stone carving to emphasize the figure, but the shadows of solar illumination were not consistent through the day at an observation point.

6 Relief of the royal family Akhenaten, Nefertiti and the three daughters 1352–1336 BC

The golden face-masks of the pharaohs of Ancient Egypt were expressions of divine brightness. In Christianity the piety of Christ was shown as dark face, but enhanced with a shining halo and shiny background. Till, and often after, the Byzantine period, the directional illumination for Christ and other holy figures was rarely used. There was no consideration for the source of illumination in the surroundings, so in composition many figures seemed incompatible with each other.

12 Hellenistic mosaic from Thmuis (Mendes), Egypt, signed by Sophilos c. 200 BC; Ptolemaic Queen Berenice II (joint ruler with her husband Ptolemy III Under Chin Shadows

The shadows on body-figures were first added in mosaic murals of early Greek periods. Here the folds of the garments and under the chin areas were made darker. Fresco wall painting technique was a predefined zone-based colour impregnation (into wet plaster) technique. Mosaics, however, did not allow over painting for colour toning like the frescoes did. Mosaics offered no scope for rework through second application, and so had to be thoroughly preplanned.

17 Frescoes at cubiculum from the Villa of P Fannius Synistor Original frescoes were repainted typically by Tempera to add details

The over-painting technique began to be used in frescoes. Such over painted shadows or ‘in-fill shadows’ continued to be used without the inclusion of ‘fall-out shadows’. Fresco artists exploited the ‘over painting’ for shadowing with reference to local direction of illumination and also for compositional balancing. Such post drawing additional effects, were not comprehensive and looked patchy.

29 ART by Leonardo da Vinci Head of a Woman (In-fill shadows + Fall out shadows)

The importance of ‘fall-out shadows’ was realized with the performing arts (recitation, drama, dances, dolls shows) enacted at night, with one or few lamps. Here the scenes and the characters, both were under shifting and varying shadows. The mood of scenes and characters were changed by intensity and position (height and sides) of the illuminating lamps. For dynamic scenes like calamities, wars, curse, etc. the source of illumination and the actors moved around, creating dynamic shadows. It was not possible to replicate such dynamism in representative or fixed arts.

19 Shadows were part of the scheme at sketch-study level ART by Jan Gosart study Drawing of Virgin and Child with Saints,1511

Early Renaissance artists were once totally dependent on religious commissions, and so the subject matter. For the religious sponsors, the importance of the figures and the depth definition of the background were important matter. The humans (and few other living beings) were made important by shading of the body, but with no concern for the for the source of illumination and consistency of the direction. The craft of good composition helped overcome many of the patchy effects.

28 Hendrick Aerts Interior of a Gothic church

Art reached a different level of expression, when the Renaissance artists learnt to include the illumination and shadows in the perspectives. It also added details and depth. This was also a time Renaissance art overcame the restraints of religious dogmas, and began to move towards the humanist art. The art now experimented with high degree of realism as well as the illusion. The trompe l’oeil art technique was used for optical illusion to form the 3rd dimension or the false depth.

21 ART by Georges de La Tour Joseph the Carpenter The Dream of St. Joseph

During the Renaissance, Leonardo da Vinci (1452-1519) studied the combined effects of illumination and shadows. He studied the source of illumination in the composition, extent and intensity of shadows and the colour range (tonal, hue) for both. The artist tackled the visible and invisible (concealed) source of illumination and reflections from surrounding surfaces. The use of multiple sources of illuminations including the reflections from surrounding surfaces (usually nearby plain walls, and not the distanced architecture or terrains), gave a new feel of colour arrangement.

23 Caravaggio The Calling of Saint Matthew introduced darkness, inseparable from light, as an iconic and psychological factor of utmost importance.

The Dutch master of domestic painting, Jan Vermeer, used light sources to create volume, and make light a part of the painting. In his ‘Woman with a Pearl Necklace’, most of the painting is taken up by a white wall reflecting the light from a window. Thus, light becomes an identifiable character of the painting. There were many like Pieter Brueghel the Elder, who created complex thematic narratives, simply out of dark-light contrasts, without bothering about the source of illumination.

24 Plfond ceiling art of Illusion making

The Baroque and Rococo periods saw the Plafond ceiling art. It created an illusive bright aeriform in upper space. The composition was designed respecting the illumination from the architectural openings in upper section of the space. It was heavier at the lower peripheral edge and became lighter (ethereal) towards the central portions. The lighter central area formed an illusive break (a sky cut-out) in the ceiling. It was viewed from a distance, so the scale and figurative expressions, both were manipulated. The height scale was high (distance of the ceiling from the floor or viewing levels), so artists finished the work in bold (rough) strokes. This was the manner of impressionist expression (that was to come years later).

25 The Geographer

Baroque painters created the impressionist effect by using rich colours to form an intense contrast between light and dark. This Baroque exuberance was however, sobered in Rococo Phase, through the calibrated illumination and softer shadows in subtle colours. Rococo sense of detail and elegance, were perhaps due to the clear and brilliant illumination through large openings and use of Opalescent and Cristallo glass.

The Renaissance artist, after debunking the religious themes, some of them became busy creating opulent art works. But other free wheelers, turned to humanism, which taught the artists to express passion, emotion, and sensation over rationale and reason. They also turned to truth and reality. In the process abandoned the Chiaroscuro style (Italian for ‘light =chiaro and dark=oscuro’), which, was based on use of strong contrasts between light and dark. Chiaroscuro was earlier practiced by Leonardo da Vinci, Caravaggio, Rembrandt and others.

31 Franz von Defregger Bauernhof Plein air sketching

Artists now moved to outdoors or plein air painting of the nature. This brought the artists not just out of dark interiors, but off their dark palettes. The Greens and Blues were the new colours.

30 Konstantin Korovin night illumination

City-based artists, who could not explore the nature, began to capture the street views, with effects of day time and night gas-light illumination. The day-light illumination in different forms, such as the cloudy skies, rains, snow fall and morning-evening twilight began to be the new art themes. The gas illumination technology developed in 1790s, became popular, first in commercial spaces, and later by 1816, gas streetlights were installed. Edison’s lamp in 1879 offered a cleaner and brighter option. But for the ‘street view’ artists, the new sources of evening and night illumination, with new tone and intensity, were exciting tools.

Paul Renard (French painter, 1871-1920)

Artists like Giorgio de Chirico, Edward Hopper, Pascal Fessler and others worked on themes in which shadows figured prominently. The fascination for the shadows was not translated into depth, but seen in large surfaces of contrasting colours, in empty town squares, sparsely furnished rooms, flat facades.

33 Edward Hopper sunny Sunday

The age of 19 C also brought in new chemistry of colours and new classifications. The colour violet only became an integral part of modern culture and life with the rise of the French Impressionists. The colours were seen as mixing of pigments and lights. Monet said: ‘Colours owe the brightness to force of contrast rather than to its inherent qualities’.

ILLUMINATION and SHADOWS -Issues of Design 34


Post 727 Gautam Shah


#1 Looking_down_from_The_Eiffel_Tower,_Paris_8_April_2007

Shadows are formed by illumination, but require something to ‘fall’ on. Some of the formative factors for shadows are, nature of illumination (solar, terrestrial and man-made), distance, intensity, direction, multiplicity of sources (original and reflected), etc.

Solar or moon eclipses cast shadows. In a solar eclipse, the Moon’s shadow falls on Earth. In a lunar eclipse, the Earth’s shadow falls on the Moon. A solar eclipse could be total, partial, or annular, whereas a lunar eclipse may be total, partial, or penumbral. Umbra, is a simple shadow, the darkest centre portion, cast by a point source of light. Penumbra, is cast by a light source with a larger surface area than the object. Antumbra is formed when the light source is covered by the larger object.

#2 Full Moon Light

We deal with Three types of natural illumination. The illumination from sun is extensive and distanced, yet strongest and so seem to be a cascade of parallel rays. The illumination from the moon is feeble and arrives like a cone. Minor planets like Mercury, Venus and stars create insignificant amount of illumination for any Design environment. Natural illumination cannot be switched off or its source position changed. The intensity can be filtered and orientation redirected. Illumination from artificial (man-made) sources are strong to diffused, but with an identifiable ‘pointed’ origin at a measurable distance. These are switchable and manipulable sources.

Forest skies

The natural and artificial sources of light, get redistributed through refraction, reflections and diffractions. These occur are due to the micro particulate matters in atmosphere, changes in the mediums that transit the light, and various interventions of atmospheric elements.

#4 1015538568_640x360

Three things are needed to perceive a shadow. The first is light. The second is an object that blocks the light. And third, another object (rather its surfaces) for the shadow to ‘fall’. Objects, except those in the air (floating-flying) have attached shadows. Attached shadows ‘fall’ on grounds that are horizontal (parallel to the gravity) inclined or undulated. The quality of a shadow, such as the length and intensity, however, depends on the angle and direction and multiplicity of the sources. We are accustomed to shadows on horizontal grounds, cast by the solar or top down lights. But shadows of bottom-up lights or reflected lights are less predictable and so intriguing. Shadows provide cues about the depths, direction of illumination, the nature of ‘fall- grounds’ and and objects’ edges.

#6 Artificial illumination for day-night cricket match

A shadow is an area with absence of light, and so darker than the directly illuminated zones, and non illuminated surfaces that lie on the opposite (back) side of the illumination. Back-face surfaces continue to receive secondary light of reflections from illuminated surroundings, though in smaller proportion. Such bak-face surfaces are lighter than the shadows.

#S hadowsin front and back side

Illumination, causing the shadows offer a range of tonal variations, some with distinct edges, some with little flutter at the edge and others seamless diffusions. Objects in solar illumination (and feeble illumination of moon etc. at night) are in the presence of ‘blue’ skies, which provide secondary brightness. The blue sky reduces the stark contrast of the shadows.

#8 Lunar shadows

Lunar environments are without the blue sky (there’s no air to refract light), the dark shadows are set against the pitch black skies. When the moon skies have presence of the Sun or Earth, due to their fortnightly passage, the regions directly illuminated seem extra ordinarily bright. The lunar surface presents varied effects of textures, at different lighting and viewing angles. It is very difficult to collate these images into a single comprehension. Moon visiting astronauts, Aldrin said that ‘continually moving back and forth from sunlight to shadow should be avoided, because it’s going to cost you some time in perception ability’. Armstrong also noted, ‘it is very easy to see in the shadows after you adapt for a while’.

#9 Lunar Darkness

Neil Armstrong, the astronaut has said ‘It’s quite dark here in the shadow, and a little hard for me to see that I have good footing.’ Armstrong and Buzz Aldrin had to conduct their scientific work in these unusual shadows, which often made parts of equipment that fell into their deep black invisible.

Long before, a person saw own reflection in water (and, later, mirror), shadows have been following like an attached tail. The shadow on the ground however were seen only as a silhouette, a solid mass, without revealing the body features. The reflection in water or mirror was better, it showed the features, shifting the left-right. Both It were existential and yet perplexing phenomena, ‘only real things can cast a shadow, and also be seen in a mirror’.

#10 Shadows in water httpspixabay.comphotosczech-republic-czech-budejovice-750417

In folklore a shadow, like a soul can get detached from the body. This reflects the belief in the shadow as being either the soul itself or a guardian spirit of the soul. Incidentally, there was also a belief that selling your soul meant you had no shadow. ‘In quarrelling about the shadow, we often lose the substance’.


1 In a story, Peter Schlemihl (character of 1814, novella, Peter Schlemihl’s Miraculous) sells his shadow to the Devil for a bottomless wallet (the gold sack of Fortunatus). But he finds the society including his love shuns him. When the devil in a new bargain wants to return his shadow in exchange for the soul, he is in dilemma, but prefers to throw away the wealth.


2 In a fairy tale, Peter Pan loses his Shadow, and makes frantic effort to find it and have it re-united with himself.3 A Wolf, in the evening felt elated on seeing his own elongated shadow but soon a larger shadow of the lion blotted it out.

The shadows are earthly matter, so metaphorically a divine body carries no shadow. The shadow-less divine figure in art-works seemed ethereal, floating in the air. Divine figures, though continued to have ‘graded shades’ for three dimensional effects of the body shape, postures, and gestures. If divine body carries no shadow, can the architectural spaces or environments (trees, rocks, mountains, water bodies) that surround them have shadows? Vampires are said to have no shadows and are said to be afraid of shadows. The gods of death are also afraid of shadows. When a human being is protected (followed) by a shadow, the person cannot be attacked (in presence of illumination) by demons or other evil supernatural entities.

Corners are affairs at street turns and junctions, formed by land-road configurations and architectural built-forms. The street corners mature historically or are arranged through intensive planning.

Building corners result largely due to the shape of the plot and its alignment to the abutting street. But building corners are also formed for architectural oddity through the obliqueness. Odd-shaped plots and flawed-alignments of streets (front and sides of the plot at odd, non-90° angles), are historical consequences or adventurism in the city planning.

1C Berlin_-_Potsdamer_Platz_-_2016

Historically streets developed over a very long period of functional moderation and visual maturation. The imposition of a diagonal pattern was to break the regimented monotony of the iron-grids of streets and generate variegated visual interests. Squared streets’ junctions have predictable quality, where one can see three opposite corners, and all have the same character, except the architectural form. The odd angled streets, however, offer outward (acute) and inward (obtuse) corners.

2a Turn in Street pixabay.com houses-old-the-walls-of-the-stone-3771884

The skewed corners, are more expressions of the road edge, sidewalks, curbs, streetlights or road sedge trees, and less of definitions emerging from the architectural design of buildings. Buildings are often, stubbornly unconcerned of the street lay. It is very common to see acute or obtuse cornered buildings imposing their ‘majestic effect’ on the right angled (90°) streets. Similarly buildings, with inward corners are placed on outwardly cornered streets.

2d corners and angles

2 e Building Corners

Very large street junctions were formed as public spaces. How to occupy, the extensive space has remained a problem. The low density and slow traffic (carts, etc.), crossing the extensive central-space was a chaotic, requiring-marked path. For managing the heavier and faster traffic, a turn-around was needed. The turn-around and its centric architecture (of memorials) fail to enliven the junction or connect the distanced corners. A corner flourishes, only in conjunction with other corners. But, that concurrence is dulled by very wide distances at the junctions. Very extensive centric spaces at road junctions, edged with tall architecture can reveal the corners, provided their design follows the street lay.

2d Barcelona panoramio Very wide junction non effective perception of the corner

In case of heavily built street junctions, the perception of the corner configuration, is more definitive due to the tall facades or their visual continuity. But at ground level, the forms of corners, however, are affected by the surface, colour, texture, reflections, occupation (storefronts, entrances, etc.) and street facilities (street light poles, signage, barricades).

Corners are formed by Vertical surfaces split-croatia-sky-blue

Corners gain a meaning, when the shape-contributing vertical surfaces are larger or taller than the perceiver. But, if the form, size and scale of the corner-forming vertical surfaces, all have the same colour, texture or pattern, the Iron-Grid pattern becomes boring. To avoid the tedious scenery of the 90° iron-grids, some cities have opted for hexagonal or floral grids.

Older towns and cities have naturally curved streets, and with the same or varied widths. Curved streets ‘turning away’ seem mysterious or less revealing, in comparison to streets ‘turning inward or towards’, which slowdown the movement and so are divulging. A curved street, or one with many crooked corners results from the illegal encroachment, and inversely street corners, gaps or setbacks are engulfed, both actions occur gradually over many years.

4 Deshaping through encroachment kimolos-cyclades-greek-greece-island-mediterranean

It is said that the curve form of the street has strong ‘perception-effect’ with the ‘left or right handed traffic movements, and culturally the prevalent script writing manner such as left to right or right to left”. But no one knows, how the East Asian (China-Japan) scripts flowing from top to down, can affect the perception of the curved streets.

4a Left - Right Turns

Street corners are also formed on straight roads with setbacks of buildings. However, when the plot width is narrow, and if the front street face is not right angled, the square form of a building does not fit into the plot shape. Such, plots have forced setbacks. Building setbacks are also enforced (for the entire form or just the upper floors) to meet the height regulations (calculated as an incidence of the angle from the opposite edge of the street).

9 Set backs Randa, village, Mallorca, road, alley, church, village center

Street corners of historical towns are multifarious junctions. The complexities arise due to the variations of mid-angles (axiality) between the adjoining streets, and their different widths. The front-edge of adjacent streets also follow their own angular convention. It becomes a polygon of unequal and differently angled faces. The Polygon, becomes non-centric, when one or few buildings, functionally and architecturally dominate the space. The streets serve not just singular way for feed or exit, but turn dual traffic channels with other back of the artery connections. Varanasi, India is a classic example of such confusions.

Buildings designed for very narrow corners (Grid-Iron building in central plaza, NYC), often face two unequal street environments. The differing environments exist due to the unequal widths of the abutting streets. The street width affects the allowable building height, the rents or sale values, degree of commercial development and the density of foot-falls (traffic). So should one adopt different architectural styles for each face?

44 different faces at Corner Collingwood Buildings corner of Pudding Chare & Collingwood Street

There have been two sets of buildings, squared and angled fronts. Squared buildings follow the street line, whereas the angled ones result to conform the sides of the plot, rather than the street. The angular front faces may manage the situation through their own articulation, typically serrations or some bizarre endowments. The street line compliant or squared-front buildings are commonly axially symmetrical.


The corner of a building, plot enforced or concept-formatted are exploited as an element for design. Acute cornered building offers little design freedom but obtuse (wide) cornered buildings have larger periphery for commercial exploitation, broader visual face and greater scope for form manipulation. Squared shape-volume buildings are sometimes, strongly affected by an askew neighbouring building, more so, if added later-on.


Buildings at street junctions, pose a design quandary, what to do with, inward or outward varieties of corners? A corner as a simple ‘union’ of vertical facades does not justify the happening of the change. An emphatic mass is used to intervene. Such a mass just separates the two faces, but will not allow the change of the character of the facades. The intervening mass, if too massive the side-faces get belittled, and if too flimsy, its capacity to interpose is lost. So, the intermediate-mass rise up as a cylinder, several floors, above the side-faces. The cylinder is capped with a crown, clock or ‘a steeple like a lantern’. No one seems to have separated the cornered edges, with emptiness (like the Brazilian Congress, Petronas Towers, Malaysia, or Time Warner Centre, NYC).

23 Sacred Groves of Kerala KAAVU

14 Sacred Green places calm water_trek peace tranquility pxhere image 1193814Natural elements in various forms have been revered in all cultures and ages. The reverence for natural elements was due to both, fear and appreciation. Natural entities have been venerated in their original whole, parts or representative adaptations. Natural elements, like the flora and fauna were worshiped in original forms, and also by equating to human body elements like arms, hands, legs, fingers, head, face, blood, semen, etc. Similarly terrestrial features like rivers, water-bodies, stones, hills, mountains, valleys, sun, moon, planets, stars, air, winds, light, rains, clouds, etc. have awed humans by their scale and power. The life processes like birth, death, fertility or procreation, growth, rejuvenation, pain, joy, love and compassion, feelings, remembrances, etc. are happenings that roused curiosity.

12 Worshiping_nature_

In India and elsewhere, unchanging patterns of far off stars were sensed as the consistency in nature, but over that imposition of certain other patterns, like the movements of moon and other planets, showed the anomalies of seasons causing floods, dry spells, earthquakes, storms and hurricanes. Man has worshiped everything real on earth, in the skies, and their symbolic representations. These astral forms over the period became extremely abstract, with no trace of the original.

18 Akhenaton-wife-Nefertiti-rays-daughters-sun-god

There were many abstract and un-explainable happenings that were challenges, like the omens, good or bad luck, irrational punishments. These experiences were formless, but associated with contextual things and that became objects for veneration. One universal belief was living beings having a soul that transcended the various body forms. The transition of a soul from one body form to another, or to a body-less ghost was accepted as the realm of existence. Souls needed places to go to, like, the underworld, heaven, hell or ethereal, and also as many animal-human body manifestations.

19 Celestial Microcosm

The mundane body forms did not adequately express the extraordinary powers that some of the souls were endowed with. So, it perhaps began with the human body gaining the heads of other beings. These body forms were of many realms and created a bizarre mix of reality, unreality and even virtual reality. Why was the first body transmutation of the head? Was there realization that the head controls the body? The Egyptian Isis, Hindu Ganesha -Son of God Shiva, many reincarnations of Vishnu, were all with modified heads. The mutant heads expressed the anger, cruelly and grotesque expressions. Reverse mutation with body of an animal and head of human were exploited to endow strength, running speed, flying or jumping powers. Wining a fight against a monster was another such expression in Sumerians, Chinese or Indian mythologies.

Attributing qualities of a living or dead person, to plants, inanimate objects or natural phenomena, is a form of Animism. It is perhaps, the most ancient form of worship. In many societies totems or emblems part of animism. In India Kalpa-Vriksha, also known as kalpataru, kalpadruma or kalpapādapa, is a wish-fulfilling divine tree. Animism perceives all natural things as ‘animated and alive’. All objects, places and creatures, and even words, sounds, smells and other sensorial expressions have spiritual significance.

In ancient periods of Europe, trees or especially groves of yew and oak were objects or places of worship. A sacred grove, a natural holy place, is known as alka (Lithuanian) and elks (Latvian). In Kerala, India sacred groves are known as ‘Kavu’, and Devrai (gods’ forest) in hilly range -Ghats of Western India. Such clusters have associated water bodies such as rivulet or pond and a presiding animistic deity (often a serpent or cobra -Naag Dev).

2 Sacred Groves ART by Arnold Böcklin

Trees have been worshiped both as Male and Female forms, and through the parts like the trunk, branches, twigs and sap representing the human arms, fingers, blood etc. Trees have been symbols of rebirth, cycle of growth in spring, fertility or procreation. The trees were associated with death and rebirth, because of their capacity to regrow from almost dried and dead condition.


While Muslims (Arabs and Bedouins) consider sacred trees especially as an abode of righteous figures’ (Wellis’) souls or as having a connection to their graves, the Druze relates sacred trees especially to the events or deeds in the lives of prophets and religious leaders’

‘According to the Druze religion only people like prophets could be ‘sacred; physical objects like, trees may be regarded only as ‘blessed’. A plant species all of whose specimens, are worshiped owing to religious tradition (regardless the exact background) has to be treated as ‘holy. Amots Dafni

The term Druid, possibly derives from the Celtic word for oak. Druids were the ceremony masters, who organized worship, sacrifices, divination, and judicial procedures at Oak groves. Many religions, like Christianity and Islam were very suspicious of the tree worship, but had to concur with the public belief that groves were sacred places of the ghosts. First public gatherings and later the churches, though first occurred in such groves. Earlier saints were buried under already accepted sacred trees. Later the saint’s graves under a tree became a beatified place. With larger buildings, Kings and high priests were buried inside the churches. The Trees and the graves seem to have usurped each others position.

The World Tree, Cosmic Tree or Tree of Life is a conceptual form that exists in many cultures of the world. It occurs as description and also as a mystical image. One of the oldest records of the World Tree is of Babylonia (about 3-4 Millennium BC). Such trees have an image with foliage (heaven), trunk (earth) and roots (underworld) and a spatial presence (position and metaphysical imagery). The position was the axis Mundi (axis of Earth’s rotation between the celestial poles) and the imagery that connected the heaven, earth, and underworld (or past, present and future).

DEPTH and DISTANCE PERCEPTION -Issues of Design 33

Post 720 by Gautam Shah


11 trier_porta_negra_left_outside_outsider_feeling_melancholy-531710.jpg!d

Depth is ‘the most existential dimension’. It is the dimension of dimensions, most inevitable experience of the world and being. Merleau-Ponty (1968) considers depth to be the primary spatiality that grounds experiences of the world. Depth designates the primary dimension that defines the distance between one’s self and other things. In this sense the depth allows the ‘coexistence’.

4 lamp-chandelier-light-souvenir-preview

Depth is often considered as the third measure. Width and Length, both are parallel to the gravity, but depth is usually vertical. Depth is measured from a high to a lower point or from front to back side. The bottom point of depth is the gravity. Depth and Height are synonymous, except that Depth is downward and Height is upward. Other terms for depth include altitude, elevation, datum, thickness, etc. Depth relates to a point, that is less accessible or fathomable, like depth of water, drawer, field or someone’s feeling. Depth differentiates the front from the the background and so reflects the intensity.

2 depth-of-field-4397882_960_720

Depth gives an ‘additional dimension to a two-dimensional (Width and Length) representation, and revels other qualities of the field’. The perception of depth, indicates information like the position of the perceiver, target and the mediating context. Depth is the distance between one’s self and other things, even, if the later are unreal. Distance gives a wider perspective, but Depth offers better or detailed insight.

Depth of measurable Distance, implies a Direction, which in turn reflect concentration, assimilation, densification and comprehension. Depth nominally relates orientation towards the Gravity. But, we say looking inside the space though it is up and away from our gravity. Similarly, we say viewing deep inside the microscope or telescope. The measure of deepness is down or inwards, like a deep place, deep waters, deep winter, etc. Emotionally depth means abstruseness, extent of sagacity and penetration. Depth of expression have intensity, density, complexity, strength and seriousness.

Visual depth defines the position of objects by connecting and separating them in space. Audio depth has many facets, the sound could be of high or low pitch, direct or reverberated. Depth of smell and Taste, both reflect the intensity of experience. Tactile Depth is the reach of experience to subcutaneous level. Depth is a measure, perceived through the sensorial faculties.

6 geograph-1489323-by-Hywel-Williams

The presence of dual (two eyes-ears) or multi-nodal (touch) perceptions define the direction, to make the depth-measure more accurate. The movement of eyes and the ability to shift the focus create a sense of visual and aural perspective. Here the far-off objects become duller and the intervening distances proportionately change.

1 perspective-3609052_960_720

Depth perception leads to judgement of distance. Depth constitutes a perceptual horizon that places the body with other things, as well as the world, such ‘interconnection is indispensable to understanding of the depth’.

9 Calgary_Tower,_Calgary,_Alberta,_Canada_-glass_floor-20June2010

Depth and Distance are different. Distance is sensed between two objects, as a multi sensorial experience and also as a contextual phenomena. Depth offers the distance and sense of volume. Distance is between two objects, and for that both the objects need to be experienced simultaneously, or alternatively bridged through several mediating things like time delay (motion picture frames) and spatial proximity, through convergence, divergence and interventions. Depth judgements can be personal, but the Distance, once measured is real. Distance manifests as remoteness or work-reach.

All depth perceptions are distinguished by the primary experience of third dimension, followed by delayed or spaced out realizations of the ‘after-effects like traces, shadows, context, front-back, etc. The visual shadows occur mainly due to illumination and recognition of tint-hue of the colour. The depth of visual shadows formed with illumination, have two qualities, the orientation (angle) and the intensity (degree of brightness). Through the phenomenon of visual perception, the other concealed depth aspects of objects emerge. Effects of surface illumination are visually perceived as change in the brightness, intensity of colour and texture. The depth dimension continuously changes, yet over a period with persistent exposure and past experiences, together, form a reliable measure.

7 carpaccio_st_jerome_lion_monastery_1509

The depth, is the realization of spatiality of objects and the realm between objects. The depth and space are synonymous. A space exists for the person, where the variable measures of depth form a dynamic and subjective experience. So depth is not a Euclidean definition or element geometrical space, but a personal rapport with the world.

This is the 33rd article (in continuation of old series -new beginning) on ISSUES of DESIGN.



Post 716 by Gautam Shah




These SIX articles are from my Micro Blog site https://wordpress.com/view/designsynopsis.wordpress.com  The articles are listed in terms of their publication sequence.  The Topics relate to #Minimalism, #Functionalism, #Frugality,

#Brevity, #Abstractions, #Reductionism









An Expression to be effective requires condensation and rearrangement of the content. The minimalism takes many different forms, in Art, it takes abstraction of form or story, in Writing, it turns to recitable poetry, and in Built forms (product design and Architecture) it needs to remain steadfast with sheer functionality.

In audio-visual expression, the reenactions are never faithful to the original, and yet the improvisation can be creative. For minimalism, the productivity is just the frugal use of means, but efficiency of the process. Minimalism is the distinctive impression created through the space and time scales. ‘In design, clarity trumps the brevity’.

The word Frugality stands against Substantial. A thing, substantial, is more ‘down to the earth’, but conversely a minimal entity is infinitesimal or spectral.

Bauhaus was about rejecting the unnecessary things that had begun to undermine the functionality of designed objects. Minimalists ask, What can we strip away without losing the purpose and identity? This is in stark contrast to Redesign Engineering ideology, which ask, What can be redefined? And the search is not a “Eureka”, but adopting and improvising the operative efficiency available in competitive offerings.


Brevity in Design relates to two fundamental measures, the TIME and SPACE. And the calibration of both, leads to efficiency. Brevity in architecture is a reflection of minimalism. It comes from a yearning to ‘shed weight’ so as to be less ‘substantial’. In architecture (and also other forms of design) ‘substantial’ translates into monumental or elaborate. A monumental entity, must confirm to the stabilizing force of gravity, and so should be large and wide-based. An elaborate entity could be multi-functional or multi-faceted, satisfying many needs.

The superfluous ‘becomes intense and dense’ in ‘classical ages’ that reappraisal becomes necessary not to discipline it but to discover the ‘new’. But such pursuit for Brevity starts at personal level, and is initially a preconception. By the time the originator and followers understand the means and methods of it, it may become a style weighed down by ‘substantial’.

Brevity as a doctrine has many subscriptive forms, like, ABC art, minimal art, reductivism, rejective art, De Stijl, neo-plasticism, Bauhaus movement, minimalism, Ludwig Mies van der Rohe’ Less Is More and Traditional Japanese art.

Brevity (First attested in English in 1509)has origins from Latin -brevitās or brevitātem, Anglo-Norman brevité, Old French brieveté (=br -brave + evity -evidence).


Aparigraha means non-possessiveness or being non-greedy. Aparigraha is the opposite of Parigraha, which means, to amass, crave, seek or seize material possessions.

Aparigraha is one of the virtues in #Jainism. It is also one of the five vows that both the householders (Sravaka) and ascetics must observe. Aparigraha is a desirable self restraint and sincerity (as a fellow citizen) for possessing what is absolutely necessary and so minimum.

(#Jainism -a religion in India, originating in roughly the same time span as Buddhism).

American scholar Richard Gregg coined the term ‘voluntary simplicity’ to describe a lifestyle purged of the inessential. My space is small but my life is big.

The concept of minimalist design was to strip everything down to its essential quality and thereby achieve simplicity. Thereafter nothing can be eliminated ‘to simplify or improve the design’. Minimalists not only ‘reconsider’ the physical qualities but spiritual meaning also.

This usually creates a design statement that is very frugal and personal. And it requires converts, who can understand, believe and accept it. If you are a design service provider that needs spirit and energy of a crusader.


In the wake of World War I, an international functionalist Design movement emerged, riding on the wave of Modernism. This was triggered by consumer product periodicals that had wide base of female subscribers.

The movement was for achieving purity in design of a product through functional relevance. This was gaining momentum with a similar trend in art, architecture and craft-artefacts. It was for reduction and restrain with the aim to remove the unnecessary and put the essential in the spotlight. These trends in Design were confirming to than current ideas of socialism and humanism.

Louis Sullivan’s 1896, idea of ‘form ever follows function‘ was more metaphysical than being practical to users’ needs. It was more reflective of ‘lack of (‘excessive’) ornamentation. Some treated as ‘bald and brutal’ manner. Philip Johnson daringly ‘held that the profession has no functional responsibility whatsoever’. The postmodern architect Peter Eisenman was more extreme, ‘I don’t do function.’

From all these personal interpretations products, art and architecture began to rely of structural stresses as expressed through straight line and right-angled geometry. This was bereft of emotion, as good design should be ‘clear and unobtrusive.’ The success of functional design was in the rationality and cost effectiveness, as it removed wastage of space and materials.


Communication occurs through writing, orally, gestural deliveries and through metaphors or graphics. Authors usually have some knowledge about the target audience.

All communications use spatial or temporal assets and so need to have minimal content. The tradition is ancient one, as knowledge was conveyed orally as Shrut Gyan (Vedic mantras are in easy to remember and in recitable form).

For content rationalization several strategies are resorted to. The contents are abstracted by removing all time-space gaps and less important information. The language in Internet chat-rooms, whatsapp, etc. shows the nature of abstraction spreading across the world. Here common words are shortened by eliminating vowels and are denoted by their phonemes. Symbols and metaphors are also used to squeeze the contents.

The contents are sequenced, with time as the operative element. Oral or gestural deliveries are sequenced in time and so are lineal. Writings can have non-lineal arrangement if aided indexing. Graphical formats are impressionistic, rely on the holistic effect.

The focus of abstraction and communication are through the retrieval and re-enactment of content. So what one strongly feels, desires, believes, becomes the force-de-majeure.

For frugality of expression beginning with a pre declaration or concluding with a definitive statement

The contents can be minimized by forming bridges (e.g. hyperlinks, bibliographies, index) to create a seamless statement or a larger concept. A well linked or cited content vouches its authenticity through circumstantial referencing.


Abstraction is a process of removing irrelevant appendages from the idea, thought or concept. This reduces the complexity and increase efficiency.

Abstraction in Art began with the removal or de-emphasis of the background or the context. This allowed the thematic concept to be perceived not just distinctly but in a different manner. The abstract Art was more concerned with the later. The newness of the object independently of its associations or attributes provided an exciting option to impressionism and expressionism. Both the -isms were substantially dependent on negation through colour, texture, form depiction, foreground-background delimitation, depth representation with intensities, perspective or scaling, and environmental connections like light and shadows.

Word Abstract derives from the Latin Abstrahere =to divert and Aabstractus =drawn away, drag away, detach, pull away, divert. It is an assimilated form of Ab =off, away from + Trahere =to draw.

In computer programming abstraction hides all but the relevant data about an object.

Acute abstraction takes away the reality. The subject is not sought or to be recognized. It has no bearing of perception like top-bottom, left-right, real or mirror. But on massing the abstract creations, do reflect the creator and that becomes the style. It is the mannerism that becomes universal. But before that universalism sets in the Art moves to something New.


The word ‘anekaāntavāda’ is a compound of two Sanskrit words: anekānta and vāda. The word anekānta itself is composed of three root words, ‘an’ (not), ‘eka’ (one) and ‘anta’ (end, side). These three together connote ‘not one ended’, ‘sided’, ‘many-sidedness’, ‘manifoldness’ or ‘many pointedness’.

According to ‘Jain’ (Indian religion that originated in roughly the same time span as Buddhism) doctrine, there is no absolute truth or reality. Anekantavada has also been interpreted, to mean non-absolutism. It is said no single concept can describe the nature of existence and the absolute truth.

Every truth is incomplete, and at best a partial truth. The ultimate truth and reality, if any, are complex and multi faceted. All knowledge must be qualified in many ways, including being affirmed and denied. Anekantavada is a fundamental doctrine of Jainism.

According Jainism reality has many facets, which are difficult to be perceived by one person or through several cycles of life. Different people interpret different aspects of it. Their conclusions are good for them and in the time-space context.

Reality is what we perceive and also of what we do not perceive. We cannot understand the reality unless we are ready to accept both. So all conditions have potentials of many truths.


CORNERS and Public Spaces

Post 696 –by Gautam Shah


This is the 4 th article of series: ‘CORNERS’.

Public spaces turn impromptu arenas with political, social and cultural interest, accompanied by some economic activities. The spaces manifest as gathering places, where events recur on specific days like full-moon days, low tide days, Sundays or annual days. Such places occur with some preexisting location cues like a built-form or a natural feature. A gathering place is the starting element of a larger concept of a social space. Defined passageways or casual pathways feed these places. The ending faces of such feed points, give unique and lasting shape to the form. The architectural contour may take ages to evolve on its own, or is remastered for a style by a ruler or plutocrat. In both the cases the essence of social place and shape of the form are sustained.

Public spaces subsist on enclosures. Enclosures occur first by barriers of natural elements like terrestrial masses, water bodies, edges of terrain contours, silhouettes. Public spaces are realized as the physical reach, limits of power or sanctimony and the sensorial perceptibility. The public spaces are delineated by the facade planes and mass of the built objects. Facades’ perimeter becomes extensively lineated when the space is multi-angular, and the connecting passages do not abut at right angles. Compared to these, variations in ‘squared public spaces’ are too few, flat and uninteresting from any spatial position and at any time of the day. The multi cornered irregularly, shaped public spaces create vivid spaces. But straight roads converted into public or pedestrian space just by eliminating the vehicular traffic create a static space.

Squared public space is rarely a natural development. The improvisations touch only the main level, but other floors continue to operate with their unrelated businesses. The public is expected to get the relief of participation by coming here out of their ghettos. The space making barriers of plants and shrubs, architectural contours, or street occupations like stalls or fountains and furniture, forge the visual depth and physical reach, but behind it, the enclosures of the facades remain unchanged. Squared architectural public spaces remain sterile entities, in spite of occupational interventions.

Different Illumination Conditions Change Functional and Visual character

The enclosures of public spaces occur by a mix of circumstances and situations. The variations of sunny and shadowed sections through the day and across the seasons are recurrent, and so taken for granted. But sunny and shadowed zones affect the functional spread, and define the usage schedules of public spaces. These also promote the use of moderating devices like awnings and screens, which in turn create vibrant edges. The varying sunlight brightens up the facades, more so when these are oriented at acute angles. The daylight variations in morning haze and in evening twilight the change the perception. The edges recede or advance, and add new effects of diffused or enhanced silhouettes. Night illumination of public spaces was once spotty, but by contrast highlighted the warmly lit interiors. Modern outdoor illumination of the floor and facades transform the spatial definitions. At night the unseen undulations, angles, depths, reach of interiors, scattered elements of space, all reveal new formations.

The environmental variations in ‘squared public spaces’ are prosaic and uninteresting, because the spaces, facades remain constant. The illumination is without any variation and consistent from all locations. Lack of angles in the space fail to create dark-light contrasts. There are few surprises. What has been formatted on the ground was perceived through as a ‘site-plan’ or site-model’, always viewed from above. Nowadays ‘walk-throughs’ as 3D modelling are attempted, yet the comprehension is extremely narrow, selective and subjective. The squared public spaces remain naive ‘compositions of horizontal and vertical surfaces which create volumes of vacancy’.

Public spaces are of three basic types: naturally evolved, remastered with buildings or landscape design, and freshly planned. The considerations are visual edges, skyline or silhouettes, spatial interventions through elemental positioning, barriers, scaling, mastering patterns, perspectives, etc. But corners are rarely ‘designed or exploited’, yet they are omnipresent and unassailable. Corners remain, characteristic essence of the space.

The enclosures, of long walls facades, make the area finite. But the feed streets or lanes serve as reference points and with their depth increase the perimeter. The corners at feed points are inclusive, because here the change is noted, but open to negotiation. The sited elements do not form the public space, but the movement of light, shadows, sources, strengths and spread of illumination, people moving around perceiving the changing orientation of objects, visual changes in colour, texture and scale, all give a temporal scale.

In this respect, Cullen made a valuable distinction between ‘enclosure’ and ‘closure’. Enclosure, he argued, provided a complete ‘private world’ that is inward -looking, static and self-sufficient. Closure, by contrast involved the division of the urban environment into a series of visually digestible and coherent ‘episodes’ retaining a sense of progression.

Vertical enclosing elements strongly scale the open spaces. The difference is acutely realized when older open spaces begin to be surrounded by tall structures. It is also true that denser and taller surroundings provide more footsteps. Public buildings like places of religion, court of law, or government offices, older monuments with large fore-spaces are compressed by taller surroundings.

In public spaces, a dramatic change is experienced when architecture and environment, together differentiate the exterior versus the interior. The realization is spatially extreme and temporally sudden, in terms of scale, temperature, and illumination. It is something akin to what Peter Zumthor has described, the transition as an incredible sense of place, an unbelievable feeling of concentration. We suddenly become aware of being enclosed, of something enveloping us, keeping us together, [and] holding us.” Crossing the threshold from outside to inside bring the sudden feeling of being confined, and in reverse direction it is a relief. The thresholds are well marked and easily sensed, though some allow a slowed transition.

In Western India, areas beyond the Fort gates of towns and cities are impromptu public spaces, formed by traders and others who have no visitation rights. But the gate leads to narrow road branching out at a point called ‘Chakla’. Chakla is a smaller scale public space as commercial hub for the insiders. It was also socially safer.

Public spaces are more envisioned by the spread of the floor. The floors unless contoured and with patterned colour and textures, do not offer any divisions. The floor patterns have been explored as coalescing and regimenting factor. The imposed geometry of the pattern connects diverse and askew elements in the open space. Floorings are free flow or with bounding the perimeter, but are not the physical edges. Other important elements of floor occupation are the shadows of sunlight and night illumination. Both of these, cast visual and functional zones.

The terms public space or gathering place is often used for large spaces that are mere cross road junctions. The surrounding areas have high commercial activity. The users are business visitors, tourists or commuters, but no local users. The movements are of Two types: One set is between adjacent feed points generating peripheral traffic, and other consists of cross traffic dividing the space into various sections. The First, creates impinging circumferential pressure on near by buildings, whereas the Second, scales the space, till the density and intensity are low remains low, giving it a perception of ‘manageable zones’.

Distinct urban connections are desired for public places, but not ones that create the impinging circumferential pressures or divide the space into various sections. The simpleton urban design strategy is to devise ‘traffic free spaces’ by blocking and diverting the movement. The plan should be to favour the local residents over the business visitors, tourists and commuters. In many of the public spaces the local residents are shifted out in favour of non resident visitors.

‘Piazzas feel like being in human-scaled outdoor rooms; very large courtyards, not like the aforementioned parking, cars and sometimes skyscrapers that are associated with plazas’.
