Small island off Iraklion, Crete, just beyond the harbor of ancient Knossos. When Theseus abandoned Ariadne after she saved him from the Labyrinth, some say that he left her on the island of Naxos. But others claim he was so anxious to be rid of her that he left her on Dia, within sight of her father's domain.
Dia (Dia), a small island which lies 40 stadia (Stadiasm.) from the
Heracleium of Cnossus in Crete (Strab. x. p. 484; Plin. iv. 20); the modern Standia.
