Apollo was the god of prophecy above all others. He was born at Delos, according to the poets; and it is there that the Homeric poems say was one of his most ancient sanctuaries. Thence, doubtless, issued the twenty famous oracles at the epoch of the colonisation. At Delphi the priestess was seated on a tripod over a crack in the rock, from which exhaled mephitic vapours that rendered her delirious, and her incoherent exclamations were reduced into hexameters by the attendant priests. But there was also at Delos the Manteion, the prophetic grotto. This has of late years been discovered along with the foundations of the temple. The Manteion is a gallery, naturally bored in the rock. The winds that penetrate it cause strange pipings and hollow moans, that served as an accompaniment to the oracles. But the most remarkable of these caverns was that of Trophonios in Beotia. Pausanius tells us the legend of its origin. The Beotians had suffered from drought for two years and sent to consult the oracle of Delphi. The reply received was that they must refer themselves to Trophonios at home. But who was the party? The Beotians had never heard of him. Then the oldest of their deputies recalled having once pursued a swarm of bees and followed it till it disappeared in a cave. That doubtless was the spot, and there, after the offering of sacrifices, Trophonios obligingly showed himself, and explained who he was and what were his powers. Since that time his oracle was much consulted, and happily an account of how he, or his priests, befooled visitors to the cave has been given us by Pausanius from his personal experience.
