A tattoo is permanent as the religiousness of Philip II once was. Devoted Catholic, one of the main (perhaps the main) focus of his entire rule was to preserve the Catholic faith, having fought his entire life against the other Christian religions and the Muslims. A suiting tattoo for him could be the phrase Deus vult, the war cry shouted by Crusaders gathering in Almafi for the First Crusade, as his own life was a personal crusade to preserve Catholicism.
