Somewhat outdated, but still a good read, is The Medieval (sic) Mind, by Henry Osborn Taylor, an overview of mediæval society.
By John Médaille
A scholastic would have told Fra Girolamo that his own St. Thomas, whom he quoted so frequently, would have refused him the right to speak as to what was good and what was bad in art. He was a moralist, a preacher; his virtue was prudence, and prudence may not judge art. Prudence might be more truly a virtue than art in so far as it made men good simply, but art was more truly a virtue than prudence in so far as it was more scientific and had more of the intellectual splendor of an authentichabitus and “life in accordance with thought is better than life in accordance with man.”
