Instead of now giving up Helen, Deiphobus and Helenus, the two next brothers, quarrelled as to which should marry her, and when she was given to Deiphobus, Helenus was so angry that he went out and wandered in the forests of Mount Ida, where he was made prisoner by Ulysses, who contrived to find out from him that Troy could never be taken while it had the Palladium within it. Accordingly, Ulysses and Diomed set out, and, climbing over the wall by night, stole the wondrous image. While the Trojans were dismayed at the loss, the Greeks seemed to have changed their minds. They took ship and went away, and all the surviving Trojans, relieved from their siege, rushed down to the shore, where all they found was a monstrous wooden horse. While they were looking at it in wonder, a Greek came out of the rocks, and told them that his name was Sinon, and that he had been cruelly left behind by the Greeks, who had grown weary of the siege and gone home, but that if the wonderful horse were once taken into Troy it would serve as another Palladium. The priest of Neptune, Laocöon, did not believe the story, and declared that Sinon was a spy; but he was cut short in his remonstrance by two huge serpents, which glided out of the sea and devoured him and his two sons. Cassandra, too, a daughter of Priam, who had the gift of prophecy, but was fated never to be believed, shrieked with despair when she saw the Trojans harnessing themselves to the horse to drag it into Troy, but nobody heeded her, and there was a great feast to dedicate it to Pallas. Helen perhaps guessed or knew what it meant, for at dark she walked round it, and called the names of Ulysses, and many other Greeks, in the voices of Penelope and the other wives at home. [Picture: Laocöon] For indeed the horse was full of Greeks; and at dark Sinon lighted a beacon as a signal to the rest, who were only waiting behind the little isle of Tenedos. Then he let the others out of the horse, and slaughter and fire reigned throughout Troy. Menelaus slew Deiphobus as he tried to rise from bed, and carried Helen down to his ship. Poor old Priam tried to put on his armour and defend Hecuba and his daughters, but Pyrrhus killed him at the altar in his palace-court; and Æneas, after seeing this, and that all was lost, hurried back to his own house, took his father Anchises on his back, and his little son Iulus in one hand, his household gods in the other, and, with his wife Creusa following, tried to escape from the burning city with his own troop of warriors. All succeeded except poor Creusa, who was lost in the throng of terrified fugitives, and was never found again; but Æneas found ships on the coast, and sailed safely away to Italy.
