 Throughout his study, Marcel Pagnol refers to the masked prisoner by mentioning "the Mask".The mask itself is explicitly mentioned in several accounts concerning the detention in Sainte-Marguerite and then at the Bastille.In Pignerol, Marcel Pagnol shows to what extent Louvois feared an encounter with Lauzun who would have doubtless recognized him, suggesting that the prisoner did not wear a mask in Pignerol.
