LetoLatin Latona In classical mythology, a Titan, the daughter of Coeus and Phoebe, and mother of the god Apollo and the goddess Artemis. Leto, pregnant by Zeus, sought a place of refuge where she might safely deliver. She finally reached the barren isle of Delos, which, according to some, was a wandering rock borne about by the waves until it was fixed to the bottom of the sea for the birth of Apollo and Artemis. In later versions the wanderings of Leto were ascribed to the jealousy of Zeus's wife, Hera, who was enraged at Leto's bearing Zeus's children. The foundation of Delphi followed immediately upon the birth of Apollo.
