Coming back to the issue of acoustics in the stones, the Shilpis displayed a remarkable skill and ingenuity in crafting “musical “pillars, which when struck at right points produce sonorous octaves. One can see such pillars in the Vijaya Vittala temple at Hampi; Meenakshi temple at Madurai; and at Sundarehwara temple at Trichendur. There might be such “musical” in other temples too. Usually such pillars are of granite and charnockites; and of different girths and volumes to produce the right octaves.
[ As regards the assembling Pillars Starnbha-sandhayah ,following are a few excerpts from Pride of India: A Glimpse Into India’s Scientific Heritage
Assembly of Pillars: It is said that there are five types of assemblies suitable for pillars; these are Mesayuddha, Trikhanda, Saubhadra, Ardhapani and Mahavrtta.
Mesayuddharn trikhandam ca saubhadram cardhapanikam I Mahavrttarn ca paficaite stambhanam sandhayah smrtah II
When there is a central tenon* (projection at the end of a piece of wood etc., with a width) a third (that of the pillar) and a length twice or two and half time its width, this is Mesayuddha (mortise – A hole to receive a tenon ,and tenon) assembly
Svavyasakarnamadhyardhadvigunam va tadayatam I Tryarnsaikam madhyarnasikham mesayuddharn prakIrtitam II)
In the Trikhanda assembly, there are three mortises and three tenons arranged as a Swastika, The assembly called Saubhadra comprises four peripheral tenons.
Svastyakararn trikhandarn syat satriciili trikhandakarn I Parsve catuhsikhopetam saubhadramiti sarnjfiitam II
An assembly is called Ardhapani (scarf joint) when half the lower and half the upper pieces are cut to size according to the thickness chosen (for the pillar)
Ardham chitva tu mule Sgre canyonyabhinivesanat I Ardhapaniriti prokto grhitaghanamanatah
When there is a semicircular section tenon at the centre, the assembly is called Mahavrtta, the well advised man employs this for circular section pillars
Ardhavrttasikharn madhye tanmahavrttarnucyate I Vrttakrtisu padesu prayunjita vicaksanah II
The assembling of (the different parts of) a pillar should be done below the middle and any assembling done above will be a source of accident; (however) the assembly which brings together the bell-capital and the abacus gives the certainty of success. When a stone pillar, with its decoration, (is to be assembled) this should be done according to the specific case.

It should be known that the assembling of the vertical pieces is done according to the disposition of the different parts of the tree; if the bottom is above and the top is below, all chance of success is lost

Bricks have been in use for thousands of years in construction of yupa the sacrificial altars and Chaithyas the early temples of the Vedic ages. Shathapatha Brahmana as also Shilpa Rathna describes the methods for moulding and burning the bricks. The Sulba sutras and Manasara detail the dimensions of the bricks of various sizes in relation to the sacrificial altars constructed for various purposes. The remnants of the Indus valley civilization too amply demonstrate the extensive use of bricks in construction of buildings and other structures.
During the later ages, the bricks were used in the temple structures mainly for erecting Gopuras the temple towers and Vimanas the domes over the sanctum.
As per the descriptions given in Manasara the bricks were made in various sizes; the size of the bricks varying from 7 inches to 26 or even to 31 inches in length. The length of the bricks were 1 ¼, 1 ½, 1 ¾ or 2 times the width .The height of the brick was ½ its width or equal to the width. Thus, bricks of different sizes, shapes, and types were made. The composition, shape and baking of a brick depended upon the use to which it was put.
Interestingly, the bricks with straight and linier edges were called male bricks; while those with a broad front side and a narrower back side or those of curved shape were called female bricks. The bricks in concave shape were called neuter bricks. The male bricks could be used in the construction of the prasada, the sanctum. The female bricks were used for the sanctum of female deities. The neuter bricks were generally not used in temple construction; but were used for lining the walls of the well.
According to Shukla Yajurveda Samhita, bricks were made from thoroughly mixed and pulverized earth and other ingredients. The earth was strengthened by mixing goat hair, fine sand, iron flake or filings and powdered stone. Earth was also mixed with ‘raal oil’, etc. and thoroughly beaten and blended in order to increase the strength of the material by enhancing the cohesion of the earth particles. Triphala concoction is said to render the earth, white ants (termite) and microbe proof.
[ Maya-mata and other Shilpa–texts give details about brick-making (Istaka-sangrahanam). Following are a few excerpts from Pride of India: A Glimpse Into India’s Scientific Heritage
Salty, off-white, black and smooth, red and granulated, these are the four kinds of clay
Usaram pandurarn krsnacikkanarn tarnrapullakarn II Mrdascatasrastasveva grhniyat tamrapullakam I
Clay suitable for making bricks and tiles must be free from gravel, pebbles, roots and bones and must be soft to touch.

Then fill the clods of clay in knee-deep water; then having mixed, pound with the feet forty times repeatedly

After soaking the clay in the sap of fig, kadamba, mango, abhaya and aksha and also in the water of myrobalan for three months, pound it

These (bricks) are in four, five, six and eight unit (widths) and twice that in length. Their depth in the middle and in the two ends (is) one fourth or one-third the width. Again these bricks should normally be dried and baked.

According to the experts, only after one, two, three or four months, again throwing (the baked bricks) in water, and extracting (them) from the water with effort, (will put the brick to use)

Brick lying was done with the aid of molds; and, the bricks were burnt in enclosed kilns. The works like Shilpa Ratna and Vastuvidya explain that the brick moulds were baked for 24 hours in a fire of firewood.
Bricks black in color or half baked or broken or defective otherwise were rejected. The bricks should be well burnt and be of uniform color.
According to Shulba Sutra, bricks measuring 22.8X11.4X5.7 cms were used in construction of walls. The Bodhayana Sulaba sutra specifies the arrangement of bricks, while constructing a wall. The brick should be directed in a dextral and laevo order. The brick ends should not be piled one over the other. The joints of the brick in each third row of brick may fall over the brick of the first row; this is the ‘Malla Lila’ style of fixing the brick, based on the arrangement of the joints of the brick.
The bricks having a smooth surface are not to be set one above the other, but are to be fixed in straight line and the wall should be of an equal thickness all over. The corners of the walls should be on the ratio of 5: 3: 4 and at right angle to each other. According to the Sumrangana Sutradhara, the square of the diagonal of the wall should be equal to the sum total of the square of the width of the wall.
It is said that the altar constructed for major sacrifices, bricks of about 200 types were used, depending upon the size and shape of the altar.
[For the details of the different types of altars and their measurements; the type and the number of bricks needed for each type of altar and their arrangement : please check here for section 5.2.1 and onward of the excellent research paper produced by Dr. Sreelatha.]
Wood has limited use in traditional temple structure of medieval times. Its application is mainly for carving doors, erecting Dwajasthamba the flag posts and for other utilities such as platforms, stands etc. But, in rare cases (as in Sri Jagannath temple at Puri or at Sri Marikamba temple in Sirsi) the principal idol dhruva bhera is made of wood. The most extensive use of the wood is of course in the construction of the Ratha the temple chariot. In rare cases as in Puri a new chariot is created each year.
Shatapatha Brahmana a Vedic text of about 1500 BC or earlier makes repeated references to wood and its applications. During its time the temples and the images were mostly made of wood (kasta shilpa). The text mentions a certain Takshaka as a highly skilled artist who carved wood. It names a number of trees the wood from which was used for various purposes. For instance Shaala (teak) and Kadira a type of hard wood was used for carving images, pillars, gnomon (sanku) and other durables. Certain other trees are also mentioned as being suitable for pillaras, posts etc: Khadi, Shaal, Stambak, Shinshipa, Aajkarni, Kshirani, Dhanvan, Pishit, Dhanwalan, Pindi, Simpa, Rahjadan, and Tinduka.
Trees such as Nibaka (Neem), Panasa (jackfruit), Asana, Sirish, Kaal, Timish, Likuch, Panas, Saptaparni, wood are said to be best for roofing work.
Coconut, Kramuk, Bamboo, Kitki, Oudumbara (silk cotton etc. wood is suited for hut constructions, ribs and rafters etc.
However use of certain trees considered holy or godlike was not recommended in temple construction. The trees such as Ashwattha (Peepal), Vata, Nagrodha (banyan), Chandana (sandalwood), Kadamba, Badari, Shami, Bilva, Parijatha, kinsuka, and Bakula, were some such sacred and godlike trees.
Chandana, Kadira, Saptaparni, Satwak, etc. were used for engraving and carving artwork.
The southern text Shilpa Rathnam states that the wood from the following is not suited for temple construction.;
Trees from a place of public resort, trees from a village or from the precincts of a temple, trees that have been burnt, trees in which are birds’ nests, trees growing on anthills, trees in which are honeycombs, trees fruiting out of season, trees supporting creepers, trees in which maggots dwell, trees growing close to tanks or wells, trees planted in the earth but reared by constant watering, trees broken by elephants, trees blown down by the wind, trees in burning-grounds, in forsaken places, or in places which had been paraclieris, withered trees, trees in which snakes live, trees in places where there are hobgoblins, devils, or corpses, trees that have fallen down of themselves, – these are all bad trees and to be avoided.
The lifetime of a tree was regarded as 103 years. The trees under the age of 16 were Baala – child trees; and those above 50 years of age were Vriddha– trees in their old age. The trees between the age of 16 and 50 years were regarded most suitable for construction of temple and homes.
Tall trees of uniform girth without knot and holes, in their youth, grown on dense hilly regions are most suited for construction of pillars. The trees that are white under the bark are in the best category; followed by those having red, yellow and dark interiors; in that order. The juicy or milky trees are preferable.
The trees that are round from the root to its apex, give a gentle fragrance, are deep rooted, are solid and temperate may be taken as masculine trees, yielding male wood.
The feminine trees have slender roots and are thick at apical part, but a much thicker middle part with no fragrance or odor in the wood.
The wood should be straight and without any knot, crevice or cavity. The structure built by joining such male and female wood last for centuries
Slender and long in the middle of the trunk and having a thick head, is a genderless tree. While the male trees serve for pillars; female trees for wall-plates, beams, and capitals; the hermaphrodite trees serve for cross-joists, joists, and rafters.
Agastya Samhita has described the wood that is to be used in a chariot, boat or an aircraft. A youthful and healthy tree should be cut and its bark removed, thereafter, it should be cut in squares after which are to be transported to the workshop where these pieces should be stored upon spread out sand in an orderly manner for 3 to 8 months for seasoning. The root and apex sides must be marked because in pillars the root side is to be kept down and apex part up.
As far as possible, only one type of wood may be used for one particular construction. The use of more than tree types of wood in a construction is not recommended.
It is said the ISI standard A-883-1957 regarding a wooden items is based on the specification s mentioned in the ancient Indian Texts
Precautions in the selection of the building materials:
No used building material should be used.
Stolen and renovated material should never be purchased.
Materials confiscated by the King should not be used.
The wood culled from the trees cut down in a cremation ground; temple, ashram or shrine should not be utilized.
Ayadi _shadvarga is a matrix of architecture and astrological calculations. According to Samarangana Sutradhara Ayaadi-shadvarga is a set of six criteria: Aaya, Vyaya, Amsha, Nakshatra, Yoni and Vara-tithi, which are applied to certain dimensions of the building and its astrological associations. The purpose of the exercise is to ascertain the longevity of the house as also the suitability to its owner. These norms are applied to temples too.
The term Aaya could be taken to mean increase or plus or profit; Vyaya – decrease or minus or loss; Nakshatra,- star of the day; Yoni – source or the orientation of the building; Vara- day of the week; and Tithi – the day in lunar calendar for construction of building and performing invocation of Vastu Purusha..
The area of the structure is divided by certain factors assigned to each element of the Aayadi Shadvarga; and the suitability or longevity of the building is ascertained from the reminder so obtained.
For instance, if the plinth area of the house is divided by 8; and the remainder is either 1 or3 or 5, then these are called Garuda garbha, Simha garbha and Rishabha garbha, which are auspicious. Hence the plinth area of the building should be manipulated or altered to arrive at an auspicious reminder.
The rule is also applied to ascertain the longevity of the building. According to this method the total area should be divided by 100 and if the reminder is more than 45, it is good and if it is more than 60 it is very good. For instance, if the length of the house 11 meters, and the width 5 meters, then its area is 11 X 5 = 55 sq.mts. Multiply the area by 27 (Nakshatra factor) , 55 X 27 = 1485. Divide the product 1485 by 100. The remainder is 85,-which indicates the projected longevity of the house. Since the reminder is more than 60, .it is a very healthy result.
There is another method for arriving at the Aayadi value. The result is categorized in to eight types of Aayas. According to this method, the area (length X breadth) is multiplied by 9; and divided by 8. The reminders 1 to 8 are interpreted as good or bad, as indicated in the following table.
|Good. Brings wealth
|Not good. ill heath of the head of the family and spouse.
| Very Good. Victory over enemies; health ,wealth and prosperity.
|Bad. Ill health and bad omens.
|Good. wealth and fortune.
|Very bad. Head of family will turn a vagabond; premature death in family.
|Good. Life of head of family and members brightens; improvent in heath and wealth.
|Very bad. Sorrow to family; and no peace.
