Helen, also known as Helen of Troy, in Latin as Helena, beautiful Helen, Helen of Argos, or Helen of Sparta, was a figure in Greek mythology said to have been the most beautiful woman in the world. She was believed to have been the daughter of Zeus and Leda, and was the sister of Clytemnestra, Castor and Pollux, Philonoe, Phoebe and Timandra. She was married to King Menelaus of Sparta "who became by her the father of Hermione, and, according to others, of Nicostratus also." Her abduction by Paris of Troy was the most immediate cause of the Trojan War.

In Greek antiquity, 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. She was just nine years old when Paris, son of the Trojan king Priam, arrived to abduct her mother, Helen.
