Canto XXXIV/1 One of the fears that any illustrator of Dante has is how to cope with his final apocalyptic monster, the three-headed Prince of Darkness in all his black grandeur. As so often the problem by accident presented its own solution. While I was working on Canto XVII/1 and fitting together the transparencies of the Turin Shroud head of Christ, I chanced to turn one of the negatives upside-down and saw in the image a weird physiognomy, which although made out of the features of Jesus seemed to be the epitome of scowling evil. Since Satan is the pattern of the Antichrist and is said to retain in his face some residue of glory, this inverted negative of the holiest of faces seemed more than apposite. Repeated thrice as the last travesty of the Trinity the undoctored features do the work. -- Source of annotation: Marvin or Ruth Sackner.
