The founder of Psychical Research, though he has not yet received the honour due to him, seems to have been King Croesus of Lydia, who reigned from 560 to 546 B.C. He carried out an interesting experiment, recorded in detail by Herodotus,2 to test the clairvoyant powers of a number of oracles. He sent embassies to seven oracles, six Greek and one Egyptian. They all started on the same day. On the hundredth day each embassy was instructed to ask its (...) oracle, “What is King Croesus, the son of Alyattes, now doing?” The answer was to be written down and brought back. The oracle of Delphi replied as follows, in hexameters, as its custom was: “I know the number of the sands and the measures of the sea. I understand the dumb, and I hear him who does not speak.” Then it went on: “There comes to my mind the smell of a strong-shelled tortoise, which is being cooked along with lamb's flesh in a brazen vessel; brass is spread beneath it, and with brass it is covered.” As a matter of fact, this answer was perfectly correct. Herodotus tells us that “having considered what would be the most difficult thing to discover and to imagine,” Croesus “cut up a tortoise and a lamb, and himself boiled them together in a brazen pot.” What happened afterwards illustrates the difficulties of this sort of investigation, difficulties which still perplex us to this day. Croesus argued, reasonably enough, that if the Delphic priestess had clairvoyant powers, she probably also had the precognitive powers, she probably also had the precognitive powers which she claimed to have. But when he consulted the oracle later about his forthcoming expedition against the Persians, he received two answers, one of which was ambiguous—“When Croesus crosses the Halys he shall destroy a great empire”—and the other correct, but too obscure to be easily interpreted.
