During the sack of Troy, the Greeks committed horrible war crimes. Neoptolemus, son of Achilles, killed the Trojan king Priam on the altar of Zeus, where he had taken refuge. Odysseus threw Hektor’s baby from the city walls.
These war crimes angered the gods, who gave the surviving Greeks many hardships on their way home. This is where Homer’s second epic, the Odyssey, starts off. Because of the curse of gods, it took Odysseus 10 years of wandering in strange lands until he was finally reunited with his wife back home in Ithaca.
