Kalaureia

Kalaureia (Ancient Greek: Καλαυρεία) or Calauria or Kalavria (Greek: Καλαυρία) is an island close to the coast of Troezen in the Peloponnesus of mainland Greece, part of the modern island-pair Poros.

Strabo describes the coastwise journey along the Hermionic Gulf:

The gulf begins at the town of Asine. Then come Hermione and Troezen; and, as one sails along the coast, one comes also to the island of Calauria, which has a circuit of one hundred and thirty stadia and is separated from the mainland by a strait four stadia wide.
