There is one side, however, of Greek religion as to which Pausanias shows himself consistently sceptical, if not incredulous. He had serious doubts as to the existence of a subterranean hell. “It is not easy,” he says, “to believe that gods have an underground abode in which the souls of the dead assemble.” He speaks of the “supposed subterranean realm” of Pluto, and in the cave at Taenarum, which was thought to be one of the mouths of hell, he looked in vain for any passage leading down to the nether world. Cerberus in particular, the hound of hell, is roughly handled by Pausanias, who ruthlessly strips him of his superfluous heads, reduces him to a commonplace serpent, and seems to take a malicious pleasure in enumerating all the places where the animal was said to have been haled up by Hercules. But though Pausanias had his doubts as to hell, he seems to have believed in the existence of the soul after death; for in a passage which has been already quoted he speaks of the punishment that awaits the wicked in another life. At the same time his belief in the doctrine was apparently not very firm; at least he refers to it somewhat hesitatingly in mentioning the Messenian tradition that the soul of the dead hero Aristomenes had fought against his old foes the Lacedaemonians at Leuctra. “The first people,” he there tells us, “who asserted that the soul of man is immortal were the Chaldeans and the Indian magicians; and some of the Greeks believed them, especially Plato, the son of Aristo. If everybody accepts this tenet, there can be no gainsaying the view that hatred of the Lacedaemonians has rankled in the heart of Aristomenes through all the ages.” [Sidenote: His attitude to various deities.]
