High Quality Content by WIKIPEDIA articles! There are literary, archaeological, epigraphic and numismatic sources of ancient Tamil history. The foremost among these sources is the Sangam literature, generally dated to the last centuries BCE to early centuries CE. The poems in Sangam literature contain vivid descriptions of the different aspects of life and society in Tamilakam during this age; scholars agree that, for the most part, these are reliable accounts. Greek and Roman literature, around the dawn of the Christian era, give details of the maritime trade between Tamilakam and the Roman empire, including the names and locations of many ports on both coasts of the Tamil country.
