Consider how Philip II of Spain and the page boy would look in profile, and how Martin I of Aragon compares with the heads on the other black and white photo below and ask yourself why some of the later Kings of Aragon would want to identify themselves with Moors the predecessors decapitated. It just doesn't add up.
Am I the only one to have noticed that the crowns on the head of the Moorish Kings are identical to the one on the Christian king? Were these Moors actually Muslims or were they Christians, or were they Moors who switched over to the to Christian side? This doesn't add up and it so obvious that one has to wonder why no one seems to have noticed it and mentioned it earlier. As they saying goes if you repeat something often enough people get to believe it even if it doesn't make sense.
