A portrait of the Trojan Prince Paris, from a side panel to the "Story of Oenone and Paris" (c.1460s) by Francesco di Giorgio Martini (Italian, 1439-1501). Paris, the son of Priam, king of Troy, appears in a number of Greek legends. Probably the best-known was his elopement with Helen, queen of Sparta, this being one of the immediate causes of the Trojan War. Later in the war, he fatally wounds Achilles in the heel with an arrow, as foretold by Achilles's mother, Thetis.
