As related in the "Aeneid", after a nine-year war on the beaches of Troy between the Danaans (Greeks from the mainland) and the Trojans, the Greek seer Calchas induces the leaders of the Greek army to win the war by means of subterfuge: build a huge wooden horse and sail away from Troy as if in defeat—leaving the horse behind as a votive offering for a safe journey home. The Trojan Horse actually contains a hand-picked team of Greek warriors hidden in its wooden belly. The Trojan priest Laocoön suspects that some menace is hidden in the horse, and he warns the Trojans not to accept the gift, crying, "." ("Do not trust the horse, Trojans! Whatever it is, I fear the Danaans, even when bringing gifts.") Immediately after Laocoön proclaims his warning, he throws a spear at the horse, which pierces its side; Virgil writes that the groan from the Greek warriors hidden within would surely have alerted the Trojans to the trick if the gods had not already ordained Troy's destruction.
