According to mythology, Zues, father of the gods, was up to his old tricks. This time it was Leto, daughter of the Titans Kronos and Phoebe, he was chasing. And when she turned herself into a quail, he did the same and caught her. Hera, Zues's wife, was so cross that she swored that Leto would find no place on earth to have her child. Pursued by Hera, Leto found refuge on a floating rocky island, which Poseidon then anchored to the sea bottom with pillars of granite. Here, under a date palm, she gave birth to twins Apollo and Artemis. Apollo, symbol of manly beauty and god of a variety of matters, including truth, light, music, prophecy, medicine, archery, and the tending of flocks and herds. Artemis, virgin huntress and goddess of chastity. The birth were attended by Arge and Opis, two maidens from the hyperborean regions of the north, which god was required to visit annually.
