Rural activities like the cultivation of ragi and sugarcane, the making of sugar from the cane, and the harvesting and drying of grain are described in the Sangam poems in detail.
(b) Markets called Angadi were established in bigger towns. Internal trade was carried by caravans of Merchants with carts and pack-animals which carried their merchandise from place to place. Most of the trade was carried on by barter. Paddy constituted the most commonly accepted medium of exchange. Salt was sold for paddy. Paddy was sold by mentioning its price in terms of salt. Honey and roots were exchanged for fish oil. There were also hawkers who carried goods to the houses of the people.
(c) During the Sangam Age, the Tamil land conducted extensive foreign trade through major port cities like Saliyur, Bandar, Naura, Tyndis, and Muziris. Major exports included spices (pepper, ginger, cardamom, cinnamon, turmeric), ivory, pearls and precious stones, while imports primarily consisted of horses, gold, and glass. The scale of this international commerce, particularly with the Roman Empire, is well-documented in The Periplus of the Red Sea and further evidenced by large caches of Roman gold and silver coins discovered across the interior of the region.
