You are wrong on the last judgment. The one at the

right lower corner is Cesena. He was Pope's master of ceremonies. Michelagelo was angery at him because complained about too much nudity in the painting. Michelagelo put donkey ears on him and wrapped snake around him. Cesena complained to the Pope. The Pope joked about it by saying to Cesena he only had judiciary over paradise and purgatory. Since Michelagelo put him in hell in the painting, he (the Pope) couldn't do anything. What a smart Pope!
