was built by Epeius and guided by Athena, from the wood of a cornel tree grove sacred to Apollo, with the inscription: "The Greeks dedicate this thank-offering to Athena for their return home". The hollow horse was filled with soldiers led by Odysseus. The rest of the army burned the camp and sailed for Tenedos. When the Trojans discovered that the Greeks were gone, believing the war was over, they "joyfully dragged the horse inside the city", while they debated what to do with it. Some thought they ought to hurl it down from the rocks, others thought they should burn it, while others said they ought to dedicate it to Athena. Both Cassandra and Laocoön warned against keeping the horse. While Cassandra had been given the gift of prophecy by Apollo, she was also cursed by Apollo never to be believed. Serpents then came out of the sea and devoured either Laocoön and one of his two sons, Laocoön and both his sons, or only his sons, a portent which so alarmed the followers of Aeneas that they withdrew to Ida. The Trojans decided to keep the horse and turned to a night of mad revelry and celebration. Sinon, an Achaean spy, signaled the fleet stationed at Tenedos when "it was midnight and the clear moon was rising" and the soldiers from inside the horse emerged and killed the guards. Sack of Troy The Achaeans entered the city and killed the sleeping population. A great massacre followed which continued into the day. Blood ran in torrents, drenched was all the earth, As Trojans and their alien helpers died. Here were men lying quelled by bitter death All up and down the city in their blood. The Trojans, fueled with desperation, fought back fiercely, despite being disorganized and leaderless. With the fighting at its height, some donned fallen enemies' attire and launched surprise counterattacks in the chaotic street fighting. Other defenders hurled down roof tiles and anything else heavy down on the rampaging attackers. The outlook was grim though, and eventually the remaining defenders were destroyed along with the whole city. Neoptolemus killed Priam, who had taken refuge at the altar of Zeus of the Courtyard. Menelaus killed Deiphobus, Helen's husband after Paris' death, and also intended to kill Helen, but, overcome by her beauty, threw down his sword and took her to the ships.
