LETO.

     Daughter of the Titans Coeus and Phoebe, Leto (Latona) was the mother by Zeus (Jupiter) of the twins Apollo and Artemis (Diana). Artemis helped to deliver her brother on the Aegean island of Delos after Leto swore to the island that the powerful god she was about to bear would build a temple there. The jealous Hera (Juno) is said to have interfered with the birth, first by threatening to destroy any land that would give Leto safe haven, and then by detaining Eileithyia, goddess of childbirth, for nine days while Leto was in labor. Bribed by the other goddesses, Eileithyia went in secret to Leto and allowed her to give birth.
    Other versions of the myth state that Leto disguised herself as a wolf to hide from Hera and traveled to Delos in just twelve days to bear her twins, then journeyed with the newborn gods to the country of Lycia. There, prevented by Lycian peasants from either washing the children in a pond (or spring) or drinking the water, Leto asked the gods to transform the people into frogs, so that they could live in water for all time. This aspect of Leto’s story is especially popular in postclassical art.
