Knights of Art by Amy Steedman

It must have been about the same time when Fra Angelico was covering the walls of San Marco with his angel pictures, that a very different kind of painter was working in the Carmine church in Florence.

This was no gentle, refined monk, but just an ordinary man of the world -- an awkward, good-natured person, who, as long as he had pictures to paint, cared for little else. Why, he would even forget to ask for payment when his work was done; and as to taking care of his clothes, or trying to keep himself tidy, that was a thing he never thought of!
