who prophesied that paris would be the cause of the fall of troy
Paris (mythology) Paris was a child of Priam and Hecuba (see the list of King Priam's children). Just before his birth, his mother dreamed that she gave birth to a flaming torch. This dream was interpreted by the seer Aesacus as a foretelling of the downfall of Troy, and he declared that the child would be the ruin of his homeland. On the day of Paris's birth, it was further announced by Aesacus that the child born of a royal Trojan that day would have to be killed to spare the kingdom, being the child that would bring about the prophecy. Though Paris was indeed born before nightfall, he was spared by Priam; Hecuba, too, was unable to kill the child, despite the urging of the priestess of Apollo, one Herophile. Instead, Paris's father prevailed upon his chief herdsman, Agelaus, to remove the child and kill him. The herdsman, unable to use a weapon against the infant, left him exposed on Mount Ida, hoping he would perish there (cf. Oedipus); he was, however, suckled by a she-bear. Returning after nine days, Agelaus was astonished to find the child still alive and brought him home in a backpack (Greek pḗra, hence by folk etymology Paris’s name) to rear as his own. He returned to Priam bearing a dog's tongue as evidence of the deed's completion.[3]
Trojan Horse According to Quintus Smyrnaeus, Odysseus thought of building a great wooden horse (the horse being the emblem of Troy), hiding an elite force inside, and fooling the Trojans into wheeling the horse into the city as a trophy. Under the leadership of Epeius, the Greeks built the wooden horse in three days. Odysseus's plan called for one man to remain outside the horse; he would act as though the Greeks had abandoned him, leaving the horse as a gift for the Trojans. An inscription was engraved on the horse reading: "For their return home, the Greeks dedicate this offering to Athena". Then they burned their tents and left to Tenedos by night. Greek soldier Sinon was "abandoned", and was to signal to the Greeks by lighting a beacon.[2] In Virgil's poem, Sinon, the only volunteer for the role, successfully convinces the Trojans that he has been left behind and that the Greeks are gone. Sinon tells the Trojans that the Horse is an offering to the goddess Athena, meant to atone for the previous desecration of her temple at Troy by the Greeks, and ensure a safe journey home for the Greek fleet. Sinon tells the Trojans that the Horse was built to be too large for them to take it into their city and gain the favor of Athena for themselves.
