“Perhaps the commonest dream symbol of transcendence is the snake, as represented by the therapeutic symbol of the Roman god of medicine Aesclepius, which has survived to modern times as a sign of the medical profession. This was originally a nonpoisonous tree snake; as we see it, coiled around the staff of the healing god, it seems to embody a kind of mediation between earth and heaven.” `Carl Jung, Man and his Symbols, page 153
