Cesare Borgia celebrates Mass on Ash Wednesday for the King of Naples and his court. According to the liturgical texts, Cesare made ​​a sign of the cross on the forehead of each participant with ash, in these words: "Remember that you are dust and to dust you shall return." But when comes the turn of King Federico d'Aragona, Cesare draws a "C" on his forehead. Thus causing the sovereign Cesare stands in contradiction with the spirit of contrition associated with this holiday.
