 The only other brightness in the picture comes from the white flesh, the red blood of the corpse, and the white knuckles of Saturn as he digs his fingers into the back of the body.There is evidence that the picture may have originally portrayed the titan with a partially erect penis, but, if ever present, this addition was lost due to the deterioration of the mural over time or during the transfer to canvas; in the picture today the area around his groin is indistinct.It may even have been overpainted deliberately before the picture was put on public display.
