Pyrrhus, called also Neoptolemus, son of Achilles; was one of the heroes concealed in the wooden horse by means of which Troy was entered, slew Priam by the altar of Zeus, and sacrificed Polyxena to the manes of his father. Andromache, the widow of Hector, fell to him on the division of the captives after the fall of Troy, and became his wife.
