expression “Trojan horse” denotes an insidious design, a cunning plan that seems innocuous at first. The euphemism originates from accounts of the Trojan War. It was the Trojan horse by legend that led to the fall of Troy.
Trojan war ignited after the abduction of Helena the beautiful — the spouse of the Spartan king Menelaus. Paris, heir to the throne of Troy, having been fascinated by the beauty of the woman, kidnapped her and took her to himself. Angry Menelaus with his brother gathered the army of Greeks and went by war on the town of the abuser.
The siege of the Spartans was long and unsuccessful, the heroes dying one by one, never managing to reach Paris. Then the Greeks went trickery. Having cut down cypress groves near the city, they built a giant horse where they hid their best warriors. According to various sources, the number of armed fighters who took refuge in the wooden sculpture ranges from nine to three thousand (other popular variants are fifty and one hundred). The giant horse was left under the walls of Troy, accompanying it with a note saying it was an offering to the goddess Athena. The Spartans themselves pretended to lift the siege and sail away.
Seeing the horse, Priest Laocoont, who knows the treachery of the Greeks, exclaimed, “Fear the Danaians, even the gifts of those who bring!” , but at this point two huge snakes crawled out of the sea and killed the priest and his sons. The sea gads were directed by Poseidon, who desired victory for Sparta. However, the Trojans took this as a kind sign, saying that the odd gift is safe.
Horse was dragged into the city and put in the acropolis. At night, the warriors trapped in it got out. They interrupted the guards, served a sign to their comrades on the ships, and unseated the gates of the city. The Spartans, who pretended to sail, hurriedly returned to Troy. Thereafter, the Greeks were able to enter the city, and Troy soon fell.
