This celebrated statue was situated at Thebes, and was either injured by Cambyses, to whom the Egyptian priests ascribed most of the mutilations of the Theban temples, or else thrown down by an earthquake. The peculiar characteristic of the statue was its giving out at various times a sound resembling the breaking of a harp-string or a metallic ring. Considerable difference has prevailed as to the reason of this sound, which has been heard in modern times, it being ascribed to the artifice of the priests, who struck the sonorous stone of which the statue is composed—to the passage of light draughts of air through the cracks, or the sudden expansion of aqueous particles, under the influence of the sun's rays. This remarkable quality of the statue is first mentioned by Strabo, who visited it about 18 B. C., and upwards of one hundred inscriptions of Greek and Roman visitors, incised upon its legs, record the visits of ancient travelers to witness the phenomenon, from the ninth year of Nero, 63 A. D., to the reign of the Emperor Severus, when it became silent. _The Head of Orpheus._ Whether the head of Orpheus spoke in the island of Lesbos, or, what is more probable, the answers were conveyed to it by the priests, as was the case with the tripod at Delphi, cannot with certainty be determined. That the imposter Alexander, however, caused his Æsculapius to speak in this manner, is expressly related by Lucian. He took, says that author, instead of a pipe, the gullet of a crane, and transmitted the voice through it to the mouth of the statue. In the fourth century, when Bishop Theophilus broke to pieces the statues at Alexandria, he found some which were hollow, and placed in such a manner against a wall that a priest could slip unperceived behind them and speak to the ignorant populace through their mouths. _Wonderful Automata._
