or Oracle, in Ancient Geography, a cave near Lebada in Boeotia, between Heliicon and Chæronea (Strabo): so called from Trophonius, an enthusiastic diviner; who, descending into this cave, pretended to give answers and pronounce oracles; and was hence called Jupiter Trophonius. Such as went down to this cave never after smiled; hence the proverbial saying of a man who has lost his mirth, That he is come out of Trophonius's cave. Though Pausanias, who writes from experience, contradicts this; affirming that persons came out of the cave affected indeed with a stupor, but that they soon after recovered themselves. See ORACLE.
