What role did Sinon play in the demise of Troy?
Sinon was a Greek warrior and the son of King Sisyphus (who was forced to roll a boulder uphill only to watch it roll back down, thus repeating the procedure forever). By pretending to desert the Greeks, Sinon was captured by the Trojans. It was Sinon who told the Trojans of the huge wooden horse being built as a peace offering from the Greeks to the Trojans. He told them its large size was to prevent the Trojans from bringing it within their city gates; doing so would make the Trojans invincible from any future invasion. His story convinced the Trojans, who boldly brought the horse within the gates. Inside, of course, were Odysseus and his soldiers, who would later creep out and open the gates for the awaiting Greek army to enter.
