Description: The small panel painting, probably originally belonging to the upper section of a small altarpiece, represents the Saint sitting on a chair with a book in his left hand and a pilgrim's staff in his right, his usual iconographic attributes. His head is surrounded by a richly punched halo, decorated like the upper edges of the panel. The painting reveals the artist’s Sienese origins: the saint's face is sullen and covered by a thick, curly beard. His garments are large and spread out before being contained within the contour lines. The sophistication of the drawing is also characteristic of Sienese Gothic painting.
