Der selige Ranieri von Borgo San Sepolcro erscheint einem römischen Kardinal im Schlaf

Der selige Ranieri von Borgo San Sepolcro erscheint einem römischen Kardinal im Schlaf, at the Gemäldegalerie Berlin, depicts a vision in which the Blessed Ranieri of Sansepolcro appears to a sleeping Roman cardinal—a miracle story connected to the Franciscan polyptych that Sassetta created for the high altar of San Francesco in Sansepolcro. The scene belongs to an ancillary panel series depicting miracles performed after the death of the holy man. The Gemäldegalerie holds several panels from this dispersed altarpiece.

The composition divides into two registers: the sleeping cardinal on a bed in an interior setting below, and the heavenly appearance of the blessed Ranieri above. Sassetta uses the contrast between the earthly interior—rendered in warm, domestic tones—and the spiritual vision above to structure the image's theological argument visually.
