Theseus

Theseus was the son of Aethra and either the Athenian king Aegeus or Poseidon (or both), both of whom lay with Aethra in the same night, and the most famous hero-king of Athens. The young Theseus had many adventures, including hunting the Calydonian Boar, joining the quest for the Golden Fleece, kidnapping the young Helen and traveling to the Underworld to abduct Persephone. He succeeded in slaying the Minotaur (a half-man, half-bull monster on King Minos' island of Crete), escaping the labyrinth with the help of Minos' daughter, Ariadne, although he later abandoned her on the island of Naxos. While on a quest in the land of the Amazons, he married the Amazonian queen Hippolyta, who bore him a son, Hippolytus, before leaving her to marry Phaedra. Phaedra bore him two sons, Demophon and Acamas, but, when she fell in love with Hippolytus, Theseus brought down a curse, resulting in the deaths of both Hippolytus and Phaedra. In other legends, Theseus invited the wandering Oedipus to stay in Athens, and also invaded Thebes in order to help King Adrastus of Argos to bury the unsuccessful 'Seven Against Thebes'. He died ignominiously when Lycomedes of Skyros pushed him off a cliff.
