 And there is no prove, that Raphael ""imitated"" anything from Michelangelo. Some of his early works closely follows those of Perugino, but better find one which follows Michelangelo. There is a big diference between ""imitation"" and ""influence"". Raphael was influenced by Michelangelo and Michelangelo was influenced by Signorelli (by his own words) and there is no sense to state about ""shameless imitations"" at all. Now, about Parmigianino and Pontormo being influenced by Last Judgement and Capella Paolina frescoes - I only pointed out obvious fact - Parmigianino was already dead by the time Michelangelo finished LJ and started Paolina frescoes and as I knew Pontormo never was in Rome at the time and later. Probably those things comes from Kenney Mencher online lectures, filled with timeline errors. He even thinks Correggio (d. 1534) was influenced by LJ, which is bizarre. As for ""Battle of Centaurs"", there is well known earlier print by Antonio del Pollaiolo which is usually pointed out as possible influence on laster masculine florentine art.
