Nothing like a good myth.

Hero and Leander is the Greek myth relating the story of Hero(Ancient Greek: Ἡρώ, Hērṓ; pron. like "hero" in English), a priestess of Aphrodite who dwelt in a tower in Sestos on the European side of the Hellespont (today's Dardanelles), and Leander (Ancient Greek: Λέανδρος, Léandros), a young man from Abydos on the opposite side of the strait. Leander fell in love with Hero and would swim every night across the Hellespont to spend time with her. Hero would light a lamp at the top of her tower to guide his way.

Succumbing to Leander's soft words and to his argument that Aphrodite, as the goddess of love, would scorn the worship of a virgin, Hero allowed him to make love to her. Their trysts lasted through a warm summer. But one stormy winter night, the waves tossed Leander in the sea and the breezes blew out Hero's light; Leander lost his way and drowned. When Hero saw his dead body, she threw herself over the edge of the tower to her death to be with him.
