Zakynthos (Greek:Ζάκυνθος [ˈzacinθos]) or Zante (/ˈzɑːnti, -teɪ, ˈzæn-/; from Venetian) is a Greek island in the Ionian Sea. It is the third largest of the Ionian Islands. Zakynthos is a separate regional unit of the Ionian Islands region, and its only municipality. It covers an area of 410 km (158 sq mi) and its coastline is roughly 123 km (76 mi) in length. The name, like all similar names ending in -nthos, is pre-Mycenaean or Pelasgian in origin. In Greek mythology the island was said to be named after Zakynthos, the son of a legendary Arcadian chief Dardanus.
