A priest of Apollo, in Troy, who having offended the god by, for one thing, advising the Trojans not to admit the wooden horse of the Greeks within the walls, was, with his two sons, while engaged in sacrificing to Poseidon, strangled to death in the coils of two enormous serpents sent to kill him, a subject which is the theme of one of the grandest relics of ancient sculpture now in existence and preserved in the Vatican.
