Paris (PAR-is). Trojan prince who caused the Trojan War by carrying off Helen, wife of the Spartan king Menelaus. The Greek allies of Menelaus besieged Troy and ultimately brought about its downfall. Their greatest fighter was Achilles, who killed the Trojan champion Hector in single combat. Achilles himself was brought down by an arrow from the bow of Paris, whose aim was guided by the god Apollo. Another picture.
