Apollo and Daphne and the River God Peneios (or Peneus)
Apollo and Daphne, Gian Lorenzo Bernini
Daphne, a nymph with whom Apollo fell in love with, trying to escape cries for her father, the river god Peneus, who turns her into a laurel tree. Apollo then made it his sacred tree, and winners at the games of his sanctuary at Delphi were crowned with laurel wreaths.
Here is the place where Apollo is said to have flayed Marsyas, when he had conquered him in the contest of skill. He hung up the skin of the conquered man, in the cavern where the spring wells forth, and hence the name of the river, Marsyas, Xenophon Anabasis
Apollo and Marsyas
Apollo was worshiped throughout the Greek world, at Delphi every four years they held the Pythian Games in his honor. He had many epithets, including Pythian Apollo (his name at Delphi), Apollo Apotropaeus (Apollo who averts evil), and Apollo Nymphegetes (Apollo who looks after the Nymphs) or Lykeios (wolf) as the god of shepherds. Apollo the central figure from the west pediment of the Temple of Zeus, at Olympia, showing him declaring victory in favor of the Lapiths in their struggle against the Centaurs. The theme is a wedding feast of the Lapith king, Perithoos one of Zeus's sons. The centaurs with a human head and torso and a horse's body were invited but they drank too much and then tried to kidnap the young women present. The Centaurs represent the Persian (horse loving) barbarians who were defeated by the Greeks in Marathon.
