Leto-Who

Leto was a female Titan who was a bride of Zeus and the mother of the twin gods Apollo and Artemis. She was the goddess of motherhood and protectress of the young. She was also a goddess of modesty and womanly demure. Hera once chased her so that she could not find a place to rest and give birth to her twins. Also, when the giant Tityos tried to abduct her, Apollo intervened and slew him with arrows.
