Detail showing the oldest known depiction of the Trojan Horse. (Note the warriors peeking out through portholes in the horse’s side.) The Mykonos vase, a pithos, is the earliest dated object (Archaic period, ca. 670 BC) which depicts the Trojan Horse during the Trojan War. It was found in 1961 on Mykonos in Greece, for which it is named, by a local islander.
