<P> While questioning Sinon , the Trojan priest Laocoön guesses the plot and warns the Trojans , in Virgil 's famous line Timeo Danaos et dona ferentes ( `` I fear Greeks , even those bearing gifts '' ) , Danai ( acc Danaos ) or Danaans ( Homer 's name for the Greeks ) being the ones who had built the Trojan Horse . However , the god Poseidon sends two sea serpents to strangle him and his sons Antiphantes and Thymbraeus before any Trojan heeds his warning . According to Apollodorus the two serpents were sent by Apollo , whom Laocoon had insulted by sleeping with his wife in front of the `` divine image '' . In the Odyssey , Homer says that Helen of Troy also guesses the plot and tries to trick and uncover the Greek soldiers inside the horse by imitating the voices of their wives , and Anticlus attempts to answer , but Odysseus shuts his mouth with his hand . King Priam 's daughter Cassandra , the soothsayer of Troy , insists that the horse will be the downfall of the city and its royal family . She too is ignored , hence their doom and loss of the war . </P>
