Like other peoples, the Greeks and Romans sought to obtain rain by magic, when prayers and processions had proved ineffectual. For example, in Arcadia, when the corn and trees were parched with drought, the priest of Zeus dipped an oak branch into a certain spring on Mount Lycaeus. Thus troubled, the water sent up a misty cloud, from which rain soon fell upon the land. A similar mode of making rain is still practised, as we have seen, in Halmahera near New Guinea. The people of Crannon in Thessaly had a bronze chariot which they kept in a temple. When they desired a shower they shook the chariot and the shower fell. Probably the rattling of the chariot was meant to imitate thunder; we have already seen that mock thunder and lightning form part of a rain-charm in Russia and Japan. The legendary Salmoneus, King of Elis, made mock thunder by dragging bronze kettles behind his chariot, or by driving over a bronze bridge, while he hurled blazing torches in imitation of lightning. It was his impious wish to mimic the thundering car of Zeus as it rolled across the vault of heaven. Indeed he declared that he was actually Zeus, and caused sacrifices to be offered to himself as such. Near a temple of Mars, outside the walls of Rome, there was kept a certain stone known as the _lapis manalis._ In time of drought the stone was dragged into Rome, and this was supposed to bring down rain immediately.
