Tamil-Brahmi, also known as Tamili or Damili, was a variant of the Brahmi script in southern India. It was used to write inscriptions in the early form of Old Tamil. The Tamil-Brahmi script has been paleographically and stratigraphically dated between the third century BCE and the first century CE, and it constitutes the earliest known writing system evidenced in many parts of Tamil Nadu, Kerala, Andhra Pradesh and Sri Lanka. Tamil Brahmi inscriptions have been found on cave entrances, stone beds, potsherds, jar burials, coins, seals, and rings.
