Kanyakumari takes its name from the Kumari Amman or Kanyakumari Temple, situated in the town, on the sea-shore, the very confluence of the three water-bodies - Bay of Bengal, Indian Ocean and the Arabian Sea. In his work on ancient India, Ptolemy had identified Kanyakumari (Cape Comorin) along with the Gulf of Mannar as a centre for pearl fishery. He also identifies Korkai, a place to the east of Kanyakumari as an emporium of pearl trade.
