Michelangelo's The Last Judgment. Saint Bartholomew is shown holding the knife of his martyrdom and his flayed skin. The face of the skin is recognizable as Michelangelo.



The fresco of The Last Judgment on the altar wall of the Sistine Chapel was commissioned by Pope Clement VII, who died shortly after assigning the commission. Paul III was instrumental in seeing that Michelangelo began and completed the project. Michelangelo labored on the project from 1534 to October 1541. The work is massive and spans the entire wall behind the altar of the Sistine Chapel. The Last Judgment is a depiction of the second coming of Christ and the apocalypse; where the souls of humanity rise and are assigned to their various fates, as judged by Christ, surrounded by the Saints.
