Dia

(Δῖα) - A noble Perrhaebian princess of Thessaly, the daughter of Deioneus. While mainstream epics state she was the wife of King Ixion and the mother of Pirithous, local Thessalian and alternative poetic traditions firmly claim that Zeus was the true biological father of her child. To seduce her, the king of Olympus transformed into a stallion. Her son Pirithous went on to become the legendary king of the Lapiths and the close companion of Theseus, a divine parentage that gave the Lapith royal house immense political authority in northern Greece.
