In Greek mythology, Hermione was the daughter of Menelaus, king of Sparta, and his wife, Helen of Troy. Prior to the Trojan War, Hermione had been betrothed by Tyndareus, her grandfather, to her cousin Orestes, son of her uncle, Agamemnon. According to Apollodorus, she was nine years old when her mother eloped with Paris, son of the Trojan king Priam.
