The Pythian Apollo From Historia Deorum Fatidicorum

Apollo, the twin brother of Diana, was the son of Jupiter and Latona. Apollo was fully adult at the time of his birth. He was considered to be the first physician and the inventor of music and song. The Greeks also acclaimed him to be the father of the bow and arrow. The famous temple of Apollo at Delphi was rebuilt five times. The first temple was formed only of laurel branches; the second was somewhat similar; the third was circular and entirely of brass; and the fourth and fifth were probably of marble, of considerable size and great beauty. No other oracle in Greece equaled in magnificence that of Delphi in the zenith of its power. Writers declared that it contained many statues of solid gold and silver, marvelous ornaments, and implements of the most valuable materials and beautiful workmanship, donated by princes and kings who came from all parts of the civilized world to consult the spirit of Apollo dwelling in this sanctuary.
