A myth is something that never happened but that is always trueso said Sallustius, a fourth-century Neo-Platonist. That wise old Greek wrote a book called On the Gods and the Cosmos, pointing out that myths are about things that happen inside our souls. One of the major mythic themes is the Quest. In literature, from ancient epics like the Ramayana and the Odyssey to modern fantasies like Harry Potter, the Quest is a theme that spans the centuries and reveals our inner life to ourselves. 2008. 48 minutes.
