What is the name of Michelangelo's greatest painting?

the Word "new" in the renaissance meant - to never have done so well before. it certainly had not todays meaning of never done before. Michelangelo certainly executed works that although the content was old certainly had never been done so well before. So he probably liked his work the most. although Artists that he had the most competition with he probably liked the most. Such as Raphael, and Garindio. For certain we can say he looked up to Donatello as a Youth while he studied at the Medici Palace in Florence Italy.

Another answer:

He did not tell us.
