The conception of a god as "saviour" or deliverer is founded on incidents in personal or national experience, when some unexpected event opens a way of escape from pressing danger. When the Gauls were advancing against Rome in 388 B.C., a strange voice of warning was heard in the street. It was neglected, but when they had been repelled, Camillus erected an altar and temple to the mysterious "Speaker," Aius Locutius, whose prophetic energy was thus manifested. In the second Punic war, when the Carthaginian general, Hannibal, was marching against the city in 211 B.C., he suddenly changed his course near the Capena gate. Again the might of an unknown deity was displayed, and the grateful Romans raised a shrine to him under the name of Tutanus Rediculus, the god who "protects and turns back." It might be the attack of an enemy, it might be the imminence of shipwreck, it might be a desolating plague, or any one of the vicissitudes of fortune, the distresses and anxieties of the soul or of the State, in the power which brought rescue or health or peace to body or mind, or life hereafter in a better world, the grateful believer recognised the energy of some superhuman being. Just as the making of the world required a creative hand, just as the arts and laws of social life were the product of some divine initiative (p. 171), just as the higher virtues belonged to a band of spiritual forces which had a kind of individuality of their own, {127} so the shaping of affairs bore witness to the interest and intervention of wills above those of man. All through the countries of the Eastern Mediterranean the greater deities, such as Apollo, Artemis, Athena, Æsculapius, Dionysus, Isis, Zeus, bore the title of "Deliverer." And in the mysteries which drew so many worshippers to their rites in the first centuries of our era, this deliverance took the form of salvation from sin, and carried with it the promise of re-birth into eternal life.
