The ancient town of Korkai, near present-day Thoothukudi, has been a center for maritime trade and pearl fishing for more than 2000 years. Ptolemy's geography refers to Korkai as a center of pearl fishing while describing commercial relations between western India and Alexandria, the chief eastern emporium of the Roman Empire. The Periplus says that the Pandyan Empire extended from Comari towards the north, including Korkai, where the pearl fisheries were. Eventually, the Vijayanagara Empire took over Thoothukudi.
