During the Trojan War, the importance of the Palladium to Troy was said to have been revealed to the Greeks by Helenus, the prophetic son of Priam. After Paris' death, Helenus left the city but was captured by Odysseus. The Greeks somehow managed to persuade the warrior seer to reveal the weakness of Troy. The Greeks learned from Helenus, that Troy would not fall while the Palladium, image or statue of Athena, remained within Troy's walls. The difficult task of stealing this sacred statue again fell upon the shoulders of Odysseus and Diomedes. Since Troy could not be captured while it safeguarded this image, the Greeks Diomedes and Odysseus made their way to the citadel in Troy by a secret passage and carried it off. In this way the Greeks were then able to enter Troy and lay it waste using the deceit of the Trojan Horse.
