Leto was one of the younger Titans and the mother of the twin gods Apollo and Artemis. She was the goddess of motherhood and, with her children, a protector of the young.
Her name and iconography suggest she was also a goddess of modesty and womanly demure. Like her sister, Asteria, she may also have been a goddess of the night, or alternatively of the light of day.
When Leto was pregnant, by Zeus, with the twins she was pursued relentlessly by the goddess Hera, who drove her from land to land preventing her from finding a place to rest and give birth. The floating island of Delos eventually provided her with refuge. Later when she was travelling to Delphi, the giant Tityus attempted to abduct her, but Apollo intervened and slew him with arrows.
