In Greek mythology, Aletes was the son of Aegisthus and Clytemnestra, the king and queen of Mycenae. He had two sisters: Erigone and Helen. When they were young, their parents were killed by Orestes, who was their half-brother and the son of Clytemnestra and Agamemnon (this was in revenge for Clytemnestra killing Agamemnon, which she did in revenge for Agamemnon killing their daughter Iphigenia). The infant Helen was also killed or at least died young.
