Narrative

After years of stalemate, the Greeks learned that Troy would not fall by force alone. Helenus son of Priam—Trojan seer second only to Cassandra in foresight, and skilled in the birds and oracles of Apollo—had withdrawn or been caught outside the walls (versions place him in Idaean anger after losing Helen to Deiphobus, or simply ambushed). Odysseus waylaid him, bound him, and brought him into the Greek camp. Under compulsion—or, in some notices, willingly once he saw the city’s doom—Helenus revealed what the fates still required. The conditions vary in order and count by source, but the Apollodorean and cyclic cluster is clear: Troy cannot be taken unless the Greeks fetch the bones of Pelops; unless Neoptolemus, Achilles’ son, fights among them; unless they bring Philoctetes and Heracles’ bow from Lemnos; and unless they steal the Palladium, the ancient image of Athena that guards the city from within. Related oracles add the need to breach the walls with the horse-stratagem once the sacred defenses fall. Helenus’s capture thus becomes the hinge of the *Little Iliad*: knowledge, not merely courage, opens the last campaigns. Odysseus and Diomedes undertake the Palladium; envoys sail for Philoctetes and Neoptolemus; the bones of Pelops are sought. Cassandra had long cried the same doom unheeded inside Troy; Helenus, taken by craft, makes the Greeks able to act on it.
