Portrait of a Pope (1630) by Giuseppe Cesari - Public Domain Catholic Painting
This portrait depicts an unidentified pope. It is a historicizing depiction of an earlier pontiff; the pope's beardless face indicates that he lived centuries before the execution of the painting, as the habit of wearing a beard did not enter into papal tradition until circa 1500. It was suggested that the sitter could be Innocent III (1198-1216), one of the most famous popes of the Middle Ages.
