Trojan Horse -A huge, hollow wooden horse that was built by the Greeks and used to gain entrance into Troy during the Trojan War. It was built by the master carpeter Epeius.  The Greeks pretended to desert the war, but instead sailed to a nearby island called Tenedos. They left behind them Sinon, who persuaded the Trojans that the horse was an offering to Athena, and that it would make Troy impregnable. Although Laocoon and Cassandra warned the Trojans, the horse was taken inside. Once night fell, the Greeks emerged from it and opened the city's gates for the returning Greek army.  The Aeneid tells this story in detail while the Odyssey briefly touches upon it.
