History
Astyanax was the son of Hector (and thus the grandson of Priam, king of Troy) and of Andromache.[1]
In the morning after the Achaeans sacked the city (after having entered it using a wooden horse full of their warriors), the Trojans were rounded up, and Achaean strategist Odysseus, supported by the seer Calchas, stated that Astyanax, as the son of Hector (killed earlier in the war by Achilles), was to be killed to prevent him from avenging his parents and city, and so Odysseus tore him from his mother and threw him from the city's walls, despite Andromache's complaints. She fainted at her son's fall, only for Achilles' son Neoptolemus to claim her for himself.[1]
