Metallurgy Wharf Building In India Vedas Tamils

Ancient Hindus had an exhaustive knowledge of Metallurgy.

References to Gold, Silver,Bronze, Copper,Zinc, iron and Steel are found in the ancient texts.

First supply of weapons were made by India to Mediterranean  around 3000 BC.

British records of the 18th century show that the country had 20,000 furnaces operating across the country indicating the geographical spread of this knowledge.

Brhad-vimana-shastra, Musadhikaranam, Slokah 54-56, 58-60, Maharsih Bharadwaja (Post Vedic Period)

Dating of Brhad-vimana-shastra Nineteenth Century

Brhad-vimana-shastra (BVS) came into being in the modern times as a revealed text, the revelation having occurred through one Mr. Anekal Subharaya Shastry (born in 1866). An (unpublished) enquiry with the descendents of the family shows that Mr. Shastry had found the manuscript and attempted glory for himself by delivering it as a revelation. Swami Dayananda Saraswati (1824: 1888) in his A treatise on Rig-veda (1875) refers to Bharadwaja’s Vimana-shastra.

Bharadwaja’s Vimana-shastra is considered a part of Yantra-sarwaswam – All about machines.

This is one of the 40 sections that Yantra-sarwaswam is made of. One school of thought places Bharadwaja in 4th century BCE.

A vast number of statements and materials presented in the ancient Vedic literatures can be shown to agree with modern scientific findings and they also reveal a highly developed scientific content in these literature.

The great cultural wealth of this knowledge is highly relevant in the modern world.

Techniques used to show this agreement include:
Marine Archaeology of underwater sites (such as Dvaraka)
– Satellite imagery of the Indus
– Sarasvata River system
– Carbon and Thermoluminiscence Dating of archaeological artifacts
– Scientific Verification of Scriptural statements
– Linguistic analysis of scripts found on archaeological artifacts
– A Study of cultural continuity in all these categories……..

Varahamihira’s Brhat-samhita describes Vajra-lepa and Vajra-sanghata.

The Ashoka Pillar is basically a sand-stone pillar coated with Vajra-Sanghata to look like a metal pillar.

Mauryan caves in Bihar also have a coating that gives the surface the look of glass.

References to metallurgy may be found in the ancient Tamil literature.

A research survey at Kodumanal has unearthed the remains of an ancient blast furnace, its circular base distinguishable by its white colour, probably the result of high temperature. Around the base, many iron slags, some with embedded burnt clay, vitrified brick-bats, many terracotta pipes with vitrified mouths and a granite slab, which may have been the anvil, have been recovered.

Absence of potsherds and other antiquities has suggested that the smelting place was located outside the boundary of habitation.

More furnaces were discovered at the same site with burnt clay pieces with rectangular holes.

The pieces were part of the furnace wall, the holes designed to allow a natural draught of air to pass through evenly into the furnace. Many vitrified crucibles were also recovered from this site; one of them notable because it was found in an in situ position.

Evidence of steel making is also found in the crucibles excavated at this site.

 In addition to iron and steel, the metallurgy seems to have possibly extended to copper, bronze, lead, silver and gold objects.

 At Arikamedu, there were indications of small-scale workshops containing the remains of working in metal, glass, semiprecious stones, ivory and shell.

 Kodumanal has yielded evidence for the practice of weaving, in the form of a number of intact terracotta spindle whorls pierced at the centre by means of an iron rod, indicating the knowledge of cotton spinning and weaving.

To further strengthen this theory, a well preserved piece of woven cotton cloth was also recovered from this site.

 Dyeing vats were spotted at Arikamedu.

Many brick structures have been located at Kaveripumpattinam during on-shore, near shore and off-shore explorations; these provide proof for building construction during Sangam age.

The on-shore structure include an I-shaped wharf and a structure that looks like a reservoir.

The wharf has a number of wooden poles planted in its structure to enable anchorage of boats and to facilitate the handling of cargo.

Among other structures, there is a Buddhist vihara with parts of it decorated using moulded bricks and stucco.

Near shore excavations yielded a brick structure and a few terracotta ring wells.

Off-shore explorations located a fifteen course brick structure, three courses of dressed stone blocks, brick bats and pottery.

 At Arikamedu, there were indications of a structure built substantially of timber, possibly a wharf.

Conical jars that could have been used for storing wine and oil have been found near structures that could have been shops or storage areas

. Evidence of continued building activity are present at this site, with the most distinctive structures being those of a possible warehouse, dyeing tanks and lined pits(wiki)
