Archeological evidence for agricultu
 and cotton. It has been deduced that agriculture most likely involved dry farming, with additional irrigation for cotton and rice; mixed cropping seems to have been undertaken to replenish the nitrogen in the soil—this also suggests a spread of labour and knowledge of different sowing and harvesting techniques. The presence of cotton seeds indicates the production of a crop aimed at craft production, which is also attested by finds of cotton and spindle whorls at Kodumanal.[45] Remains of structures that resemble an artificial water reservoir have been located at different sites. In Arikamedu, a few terracotta ring-wells were found at the bottom of the reservoir; it has been suggested that the ring wells were to assure the supply of water during the dry season.[46][47][48]
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.[49] Evidence of steel making is also found in the crucibles excavated at this site.[50] In addition to iron and steel, the metallurgy seems to have possibly extended to copper, bronze, lead, silver and gold objects.[51] At Arikamedu, there were indications of small-scale workshops containing the remains of working in metal, glass, semiprecious stones, ivory and shell.[48] 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.[52] Dyeing vats were spotted at Arikamedu.[53]
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.[54] 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.[48]
Kodumanal was popular for the gem-cutting industry and manufacture of jewels. Sites bearing natural reserves of semi-precious stones such as beryls, sapphire and quartz are located in the vicinity of Kodumanal. Beads of sapphire, beryl, agate, carnelian, amethyst, lapis lazulli, jasper, garnet, soapstone and quartz were unearthed from here. The samples were in different manufacturing stages – finished, semi-finished, drilled and undrilled, polished and unpolished and in the form of raw material. Chips and stone slabs, one with a few grooved beads, clearly demonstrate that these were manufactured locally at Kodumanal.Excavations at Korkai have yielded a large number of pearl oyesters at different levels, indicating the practice of the trade in this region.[56] Some of the objects excavated from Kodumanal show a lot of artistic features such as paintings on the pottery, engravings on the beads, hexagonal designs on beads, inlay work in a tiger figurine and engraved shell bangles. More than ten designs are noticed in the paintings and bead etchings.[57]
There are remnants of many of the items imported from and exported to the Roman empire, at Arikamedu. Imported items recovered from here include ceramics such as amphorae and sherds of Arretine ware, glass bowls, Roman lamps, a crystal gem and an object resembling a stylus. Artifacts that may have been meant for export include jewellery, worked ivory, textiles and perhaps leather or leather-related products.[58] Similar looking ornaments have been recovered from Arikamedu and Palatine Hill in Rome, further confirming that this site was a leading trade center.[48] The Pandyan port city Alagankulam has yielded a rouletted pottery ware that bears the figure of a ship on the shoulder portion. This figure is very similar to a finding reported from Ostia, an ancient port of the Romans.[59] Wharf-like structures found at many port cities indicate that they might have been used as docks. Based on marine explorations of various port-sites, it has been suggested that stone anchors may have been used since as early as the 3rd century BCE.[60]
