Apollo????

One of the twelve senior gods of ancient Greece and Rome and the only one who would keep his name after being added to the Roman pantheon. The parents of Apollo and his twin sister, Artemis were Zeus and the goddess Leto. Artemis was the firstborn of the two. The duality of Artemis, moon goddess and Apollo, sun god, stands as one of the clearest archetypes in Greek myth.

Apollo and his sister were born on the island of Delos in the northern Cyclades. The story behind this is that the powerful Hera, as usual insanely jealous of Zeus' escapades, forbade all land to shelter Leto for the birth of her children and thus condemned her to roam the world, chased by the fearsome serpent Python, looking for a place to have them. What she finally found was the island of Delos, a creation of Poseidon floating freely on the ocean with nothing but a palm tree on it. This would become the birthplace of the twin gods and later one of the most sacred places of antiquity. Hera though, still had to be bribed into letting Ilythia, midwife of the gods, attend the birth but, vain goddess that she was, caved in on the ninth day of Leto's labour and upon being offered a necklace of gold and amber. Thus it came to be that the barren island of Delos was blessed by Zeus.

When Hera discovered that Leto was pregnant and that Zeus was the father, she banned Leto from giving birth on "terra firma", or the mainland, or any island. In her wanderings, Leto found the newly created floating island of Delos, which was neither mainland nor a real island, and she gave birth there. The island was surrounded by swans. Afterwards, Zeus secured Delos to the bottom of the ocean. This island later became sacred to Apollo.

It is also stated that Hera kidnapped Ilithyia, the goddess of childbirth, to prevent Leto from going into labor. The other gods tricked Hera into letting her go by offering her a necklace, nine yards long, of amber. Mythographers agree that Artemis was born first and then assisted with the birth of Apollo, or that Artemis was born one day before Apollo, on the island of Ortygia and that she helped Leto cross the sea to Delos the next day to give birth to Apollo. Apollo was born on the seventh day (ἡβδομαγενης) of the month Thargelion —according to Delian tradition— or of the month Bysios— according to Delphian tradition. The seventh and twentieth, the days of the new and full moon, were ever afterwards held sacred to him.

In Greek and Roman mythology, Apollo, the ideal of the kouros (a beardless youth), was the archer-god of medicine and healing, light, truth, archery and also a bringer of death-dealing plague.

Apollo is son of Zeus and Leto, and the twin brother of the chaste huntress Artemis, who took the place of Selene in some myths as goddess of the moon.

In Hellenistic times, especially during the 3rd century BC, as Apollo Helios he became identified among Greeks with Helios, god of the sun, and his sister similarly equated with Selene, goddess of the moon.
