Aphrodite is the Greek goddess of love and beauty. She is the most beautiful of all the Olympians and married to Hephaestus, the lame god of blacksmiths and fire, but her lover is Ares, the hotheaded god of war. She was born when Kronos, king of the Titans, severed Ouranos' genitals and threw them into the sea. This generated sea foam, and from the foam Aphrodite sprang.
When Aphrodite traveled to Olympus, all the male gods looked upon her and immediately, all of them wanted to marry her. There was a giant argument, which Zeus, Lord of the Air, god of lightning, and king of the gods, calmed. He settled the matter by announcing that Hephaestus, the only god who hadn't argued over Aphrodite, would marry her.
She has mothered many demigod children, the most famous being Aeneas, who fled Troy and began the great Roman Empire.
