What mythical Greek king killed his father and married his mother.
Polynices In Greek mythology, Polynices, sometimes spelled Polyneices, (Greek: Πολυνείκης, transl. "Polyneíkes", "manifold strife") was the son of Oedipus and Jocasta. His wife was Argea. His father, Oedipus, was discovered to have killed his father and married his mother, and was expelled from Thebes, leaving his sons Eteocles and Polynices to rule. Because of a curse put on them by their father Oedipus, the sons Polynices and Eteocles did not share the rule peacefully and died as a result by killing each other in a battle for the control of Thebes.
Anaxagoras (mythology) In Greek mythology, Anaxagoras (Greek: Αναξαγόρας ) was a king of Argos and son of either Megapenthes or his son Argeus. The prince, Anaxagoras' son, suffered from a strange malady and the king offered a reward for anybody that could heal him. Melampus, a local seer, killed an ox and talked to the vultures that came to eat the corpse. They said that the last time they had had such a feast was when the king made a sacrifice. They told Melampus that the prince had been frightened of the big, bloody knife and the king tossed it aside to calm the child. It had hit a tree and injured a hamadryad, who cursed the prince with the sickness. The hamadryad told Melampus that the boy would be healed if the knife was taken out of the trunk of the tree and boiled, then the rusty water that resulted drunk by the prince. Melampus followed her directions and demanded two thirds of the kingdom for himself, and one third for his brother, Bias. The king ultimately agreed. When the women of Argos were driven mad by Dionysus, in the reign of Anaxagoras, Melampus was brought in to cure them, but demanded a third of the kingdom as payment. The king refused, but the women became wilder than ever, and he was forced to seek out Melampus again, who this time demanded both a third for himself and another third for his brother Bias. Sometimes, this story is told not of Anaxagoras, but of his grandfather, Proetus. Anaxagoras was succeeded by his son Alector. His house lasted longer than those of Bias and Melampus, and eventually the kingdom was reunited under its last member, Cyanippus.
