Its a because "Of the Greeks who made it back to their homes Odysseus was fated to wander the longest — a full ten years — and he knew it. Among the Trojan women Hecuba fell to him, an old harridan now who could not forgive the way Odysseus had thrown her grandson Astyanax from the walls of Troy. Odysseus' ships were hit by the storm raised by Athena and were blown to Thrace. Sick of Hecuba's insults, he and his men stoned her to death."
