Today was the memorial in the Roman Martyrology for Blessed Giovanni da Fiesole, more commonly known as Fra Angelico or Beato Angelico. He was born Guido di Pietro in the 1390s and became a Dominican friar at some point. We do not know when he started painting; he seems to have started with illuminating manuscripts, but in any case he became one of the foremost painters of the Renaissance. According to some stories, the pope offered to make him archbishop of Florence and he refused; if it at all happened, this was probably for the best, since it meant he could keep painting.
