_Book II._ With the eyes of all present upon him, Aeneas related how the Greeks finally devised a colossal wooden horse, wherein their bravest chiefs remained concealed while the remainder of their forces pretended to sail home, although they anchored behind a neighboring island to await the signal to return and sack Troy. Overjoyed by the departure of the foe, the Trojans hastened down to the shore, where, on discovering the huge wooden horse, they joyfully proposed to drag it into their city as a trophy. In vain their priest, Laocoon, implored them to desist, hurling his spear at the horse to prove it was hollow and hence might conceal some foe. This daring and apparent sacrilege horrified the Trojans, who, having secured a Greek fugitive in a swamp near by, besought him to disclose what purpose the horse was to serve. Pretending to have suffered great injustice at the Greeks' hands, the slave (Sinon) replied that if they removed the wooden horse into their walls the Trojans would greatly endanger the safety of their foes, who had left it on the shore to propitiate Neptune. Enticed by this prospect, the Trojans proved more eager than ever to drag the horse into their city, even though it necessitated pulling down part of their walls. Meantime part of the crowd gathered about Laocoon who was to offer public thanks on the sea-shore, but, even while he was standing at the altar, attended by his sons, two huge serpents arose out of the sea and, coiling fiercely around priest and both acolytes, throttled them in spite of their efforts. He strains his strength their knots to tear, While gore and slime his fillets smear, And to the unregardful skies Sends up his agonizing cries. On seeing this, the horror-struck Trojans immediately concluded Laocoon was being punished for having attacked the wooden horse, which they joyfully dragged into Troy, although the prophet-princess, Cassandra, besought them to desist, foretelling all manner of woe.
