Original: Vasari claims that at this time Fra Angelico was offered by Pope Nicholas V the Archbishopric of Florence, and that he refused it, recommending another friar for the position.
Simplified: Vasari says that one of the popes (it might have been Eugenius or Pope Nichoas V) asked Fra Angelico if he would like the very important job of Archbishop of Florence. But Fra Angelico did not want such a high job and he suggested the name of another friar for the position.
