Helen of Troy, also known as Helen of Sparta, or simply Helen, was said to have been the most beautiful woman in the world, who was married to King Menelaus of Sparta, but eloped with Prince Paris of Troy, resulting in the Trojan War when the Achaeans set out to reclaim her and bring her back to Sparta. She was believed to have been the daughter of Zeus and Leda, and was the sister of Clytemnestra and Castor and Polydeuces.
