Saint Gregory Magnus (San Gregorio Magno)

In contrast to other similar series attributed to Goya (those of Muel and Remolinos), the pendentives of Calatayud depict the four Fathers of the Western Church accompanied by their saints' attributes and traditional iconography, which are depicted in great detail. Saint Gregory Magnus is shown wearing the papal tiara and triple-bar cross, writing in a book inspired by the Holy Spirit who appears by his side in the form of a dove. Saint Ambrose is dressed in a pontifical robes with a bishop's miter and crosier, reading a book which is held by a small angel. Saint Jerome, bald and bearded, wears cardinal's robes and writes in a book with a quill. At his feet there is a lion. Saint Augustine, also dressed in episcopal attire, is depicted with an expression of ecstasy, his arms extended, and a flaming heart in his left hand.

The four figures are seated on clouds which overflow their architectural frame. The background is dark blue. Despite having undergone restoration work these paintings as a group have a rather dirty aspect, doubtless due to the distortion of the bitumen or asphalt applied to the panel. They are characterized by hard lines and well-defined outlines, with highlights applied for effect at the edges and a colour palette of cool tones. The technique employed is somewhat sketchy in nature, using wide and vigorous brushstrokes which are not always applied judiciously.

Saint Gregory Magnus is seated on a throne of clouds dressed in a vast cape in golden hues with a papal tiara and cross. He is in the middle of writing with a quill in a great book which he holds in his left hand, inspired by the Holy Spirit that manifests itself to his left in the form of a dove. A small angel on the left holds the triple-bar cross.

This pendentive occupies the corner of the Evangelical side closest to the presbytery.
