According to
Bhadriraju Krishnamurti, Tamil, as a Dravidian language, descends from
Proto-Dravidian, a
proto-language. Linguistic reconstruction suggests that Proto-Dravidian was spoken around the third
millennium BCE, possibly in the region around the lower
Godavari river basin in peninsular India. The material evidence suggests that the speakers of Proto-Dravidian were of the culture associated with the
Neolithic complexes of
South India. The earliest
epigraphic attestations of Tamil are generally taken to have been written from the 2nd century BCE. Among Indian languages, Tamil has the most ancient non-
Sanskritic Indian literature. Scholars categorise the attested history of the language into three periods: Old Tamil (300 BCE–700 CE), Middle Tamil (700–1600) and Modern Tamil (1600–present). There are a number of apparent
Tamil loanwords in Biblical Hebrew dating to before 500 BCE, the oldest attestation of the language.
John Guy states that Tamil was the
lingua franca for
early maritime traders from India. Tamils began to trade with
Greece,
Rome,
Egypt,
China,
Southeast Asia,
Sri Lanka, and
Tibet. Their ports were Tondi,
Musiri and
Comari, Colchi, Poduke and Sopatma. This was done during the period of Tamil independence from 600 BCE to 300 CE. The different types of ships that would go into the port were small vessels, large vessels, and ocean-going vessels. They received the largest number the Roman coins-hoards in Tamil. This ranges from different emperors of Rome as their dates on the coins and as well as the emperors on the coins are different. This trade even continued to the end of the Roman Empire and continued into the time of the
Byzantine Empire. The Tamils also traded along the
Red Sea as goods such as potsherds were found in excavated sites. Rice and salt were popular goods that came out as exports as well as used as currency for bargaining. They were used as a means of bartering as they were able to transport large amounts and the demand for these items was always there. There was a port called Cholas that traded with the west and the Malaya coast. There were large amounts of Roulette potteries and Roman coins were found in a brick jetty that they would put items into so they would be ready for when they needed to unload them a mound in
Arikamedu with Rouletted ware,
amphorae, conical jars,
agate, and
chalcedony. Two of the port cities were later destroyed by tsunamis. These were the cities of Thenmadurai and Kapatapuram. Archaeologist T. Satyamurth found 160 urns at their dig site. Dr. Jagor found 9000 objectives such as pottery, weapons, vessels, ornaments, stone beads, clothes, bones, ivory, sandalwood, and stone implements for grinding. The population wore cotton clothes and adorned the neck with ornaments made of beads, copper, and bronze. ==Literary work==
