Tyndis

Tyndis (Ancient Greek: Τύνδις, Tamil: Thondi) was an ancient south Indian seaport/harbor-town mentioned in the Graeco-Roman writings. It was located north of port Muziris (Muchiri) — by around 500 stadia — in the country of the Chera rulers. No archaeological evidence has been found for Tyndis.

Chera rulers of early historic south India (c. second century BCE - c. third century CE) had their headquarters at Karur (Karuvur) in the interior Tamil Nadu and harbors at Muziris (Muchiri) and Tyndis (Thondi) on the Malabar Coast (present-day Kerala). There are several references to a port with the name Thondi, on the Kerala coast, in the Chera country, in early historic Tamil texts.

Thondi, a town with same name in the Pandya country, on the eastern coast of the peninsula, is also mentioned in early Tamil literature. This town still exists with the same name.
