Who 's figure is at the center of Michelangelo 's " The Last Judgement " ?
On seeing Michelangelo 's prophets , Raphael went back to the picture of the Prophet Isaiah that he was painting on a column in the Church of Sant'Agostino and , according to Vasari , although it was finished , he scraped it off the wall and repainted it in a much more powerful manner , in imitation of Michelangelo .
