Saint Gregory Magnus (San Gregorio Magno)

The figure identified as Saint Gregory Magnus is not wearing the tiara as would befit the Supreme Pontiff; rather, he is shown wearing a miter. He is sitting on clouds, receiving inspiration from the Holy Spirit, represented by a ray of white light which travels directly to his ear as he prepares to write in the illuminated manuscript in his hands. The saint is dressed in a gold damask cope with a pale green lining. The sleeves of his robes are made of white lace. A little angel, the youngest of all those depicted in this set of pendentives, holds his crosier; however, the saint should actually be shown carrying the traditional double cross.
