In Greek mythology, Helen of Troy was said to have been the most beautiful woman in the world. She was married to King Menelaus of Sparta but was abducted by Prince Paris of Troy after the goddess Aphrodite promised her to him in the Judgement of Paris. This resulted in the Trojan War when the Achaeans set out to reclaim her. She was believed to have been the daughter of Zeus and Leda, and was the sister of Clytemnestra, Castor and Polydeuces, Philonoe, Phoebe and Timandra.

Her beauty inspired artists of all times to represent her, frequently as the personification of ideal human beauty. Images of Helen start appearing in the 7th century BCE. In classical Greece, her abduction by Paris – or escape with him – was a popular motif.
