Recently I watched the movie "Kingdom of Heaven", where Baldwin IV., due to his lepracy wears a mask covering his deformed face. In the series "Knightfall" the knights of the order of St. Lacarus, also mostly lepers, wear masks and in the stategy game "Crusader Kings III" characters who suffered face deformations due to battle injuries wear masks. Are this masks historical? I did some own research lookimg up sources and encyclopedia articles about Baldwin IV., Lepracy, the order of St. Lacarus and masks in medieval times in general, but I did not find any evidrnce of masks covering face deformations. But if anyone has any references that I missed, I would be glad for a response.
