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 . 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 .
