Origin of Apollo:
Being his usual self, Zeus wooed the goddess, Leto, and she became pregnant with twins. In a jealous rage, Hera called on Gaia, Mother Earth, to keep Leto from a resting place. Leto finally fled to the island of Delos that had been created for her by Poseidon. Even so, Hera did not allow Eileithyia, the goddess of childbirth, to let Leto give birth. The other goddesses felt sorry for Leto, so they brought Hera a beautiful necklace made with amber and gold. They promised the give Hera the necklace if she would allow Leto to give birth. Reluctantly, Hera agreed, and Leto gave birth to Apollo and Artemis.
