Origin:

The Roman writer, Virgil,  wrote the Aeneid. In it, the Greek army tried for ten years to conquer the city of Troy.  In the end, the Greeks played the Trojans a trick. They pretended to leave away and left behind  a large wooden horse as a gift. In it, hundreds of Greek soldiers were hidden because the belly of the horse was hollow. When the Trojans pulled that horse into the city, the Greeks went out at night and defeated the Trojans, conquering the city as a consequence.
