Apollo, enraged at the insult offered to his priest, Chryses, sends a pestilence upon the Greeks. A council is called, and Agamemnon, being compelled to restore the daughter of Chryses, whom he had taken from him, in revenge deprives Achilles of Hippodameia. Achilles resigns her, but refuses to aid the Greeks in battle, and at his request, his mother, Thetis, petitions Jove to honour her offended son at the expense of the Greeks. Jupiter, despite the opposition of Juno, grants her request.
