Older examples of the Brahmi script appear to be on fragments of pottery from the trading town of Anuradhapura in Sri Lanka, which have been dated to the early 400 BCE. Even earlier evidence of the Tamil -Brahmi script has been discovered on pieces of pottery in Adichanallur, Tamil Nadu. Radio-carbon dating has established that they belonged to the 6th-century BCE.
