In Greek mythology, Tiresias (/taɪˈriːsiəs/; Ancient Greek: Τειρεσίας, romanized: Teiresías) was a blind prophet of Apollo in Thebes, famous for clairvoyance and for being transformed into a woman for seven years. He was the son of the shepherd Everes and the nymph Chariclo.[1] Tiresias participated fully in seven generations in Thebes, beginning as advisor to Cadmus himself. Cadmus was a king of Thebes and the maternal grandfather of the god of wine, Dionysus.
