or Oracle, a cave near Leba- s in Boeotia, between Helicon and Cheronæa (Strabo); so called from Trophonius, an enthusiastic diviner, who, des- cending into this cave, pretended to give answers and pro- nounce oracles, and was hence called Jupiter Trophonius, such as entered this cave never afterwards smiled; and hence the proverbial saying of a man who has lost his mirth, that he is come out of Trophonius's cave. Dr Clarke found the cave choked up with stones.
