He is not mentioned by Homer, but his story as given in Virgil's Aeneid and other accounts presents him as a treacherous agent of the Greeks who misleads the Trojans and encourages them to bring the Trojan Horse inside the city. He sometimes appears in art, usually being dragged into Troy as a captive with the horse behind him.
