Syracuse was the greatest city of ancient Sicily. Founded from Corinth in 733 BC, it was the only Sicilian mint to strike Tetradrachms from the beginning of its coinage in about 515 BC. The patron goddess of Syracuse, Artemis-Arethusa, whose fresh water spring was on the island Ortygia, is surrounded by three or four dolphins of the salt sea of the twin harbors of Syracuse.
