Tyndis

[2] Chera rulers of early historic south India (c. second century BCE - c. third century CE[4]) 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).

[4] There are several references to a port with the name Thondi, on the Kerala coast, in the Chera country, in early historic Tamil texts.

[2][4] Thondi, a town with same name in the Pandya country, on the eastern coast of the peninsula, is also mentioned in early Tamil literature.

[2] In some occasions, Chera ruler of Thondi is directly named as "Chenkol Kuttuvan" or Cheraman Ko Kothai Marpan.

[2] The Chera ruler, according to early Tamil poems, fixed the tooth of his enemy chieftain "muvan" on the gate of this palace.

[2] He also handed out coins to bards or poets and, in once instance, gifted varudai (mountain) goats from the Deccan region (?)
