Quartigod son of Achilles by Deidamia of Scyros, called Pyrrhus at birth. Indispensable to the fall of Troy, he was fetched from Scyros by Odysseus, hid in the wooden horse, and at the sack killed Priam at the altar and flung Astyanax from the walls. He took Andromache as concubine (fathering Molossus, eponym of the Molossians) and married Hermione, the contested betrothed of Orestes; for that quarrel he was slain at Delphi and buried in the sanctuary, where he received hero-cult. He is the unregistered husband named in the registry Hermione entry.
