Michelangelo isn't the only famous artist who worked on the Sistine Chapel. Sixtus IV entrusted the frescoes on the walls to other famous painters, such as Sandro Boticelli, Domenico Ghirlandaio, and Pietro Perugino; Michelangelo was hired later by Pope Julius II for the ceiling (which originally had been painted with stars on a blue background) and by Clement VII for the Last Judgment.
