Cross of Alcoraz
The Cross of Alcoraz is the name given to a heraldic coat of arms and flag made up of the Cross of Saint George, or cross of gules on Argent, with a Moor's head in each quarter. The earliest documented evidence of these arms is in a rare lead-sealed decree from the chancery of Peter III of Aragon, circa 1281, most likely used as the King's Coat of arms, alluding to the spirit of the Crusades and his ancestral namesake, Peter I of Aragon.
