Who was Biagio da Cesena and why did Michelangelo paint him in hell?

Biagio da Cesena was a 16th-century Roman judge and a prominent figure in the Vatican, known for his disapproval of Michelangelo's work, particularly the nudity depicted in the Sistine Chapel's frescoes. In response to his criticism, Michelangelo famously painted Biagio in hell in "The Last Judgment," depicting him as a flayed man being eaten by a serpent. This act served as both a personal affront and a commentary on the tensions between artistic expression and moral authority during the Renaissance. The inclusion of Biagio in hell was a way for Michelangelo to assert his artistic vision against the constraints imposed by critics like him.
