The daughter of Titans, Leto was known as the hidden one, and her name came to be used for the Moon. She bestowed her qualities of being unnoticed or unobserved upon the beasts of earth. Her beauty caught the eye of Zeus, however, by whom she gave birth to the twin gods Artemis and Apollo. This act made her an enemy of Hera, Zeus’s wife. She was principally worshipped in Greek Asia Minor, and usually together with her twin children.
