Sant’Ambrogio bishop and patron saint of Milan, is depicted with Bishop’s robes, miter and pastoral. St. Augustine is represented without episcopal robes, with a large book in his hands to emphasize his doctoral authorities and the unquestioned wisdom. The iconography of Saint Jerome, on the left, is that of a hermit, but no cardinal vestment depicted with a red cape. The four Church fathers sit on a throne of clouds and are surmounted by a pair of cherubim of winged cherubs holding up the hat of the Patriarch. At their feet, in the foreground, we find a circle of angels with book, pen and ink holder in hand. We assume that this painting was the model for the decoration of a ceiling.
