or Oracle, in Ancient Geography, a cave near Lebadia in Boeotia, between Helicon and Cheronæa (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 affirms that persons came out of the cave affected indeed with a stupor, but that they soon after recovered themselves. Dr Clarke found the cave choked up with stones. See Oracle.
