Who was the mythical youth who drowned in the hellespont?

The mythical youth who drowned in the Hellespont was Leander. He was known for his passionate love for Hero, a priestess of Aphrodite, who lived on the opposite shore. Each night, Leander would swim across the Hellespont to be with her, guided by the light of a lantern she would hold. Tragically, during a stormy night, he drowned while trying to cross, leading Hero to take her own life in grief.
