Blessed Ranieri Delivering the Poor from a Prison in Florence

Sassetta's Blessed Ranieri Delivering the Poor from a Prison in Florence, painted around 1437, forms part of the predella of the Arte della Lana altarpiece. The scene depicts a local Franciscan blessed performing a miraculous liberation, connecting Sienese civic pride with Franciscan devotion in a characteristically intimate narrative. Sassetta — Stefano di Giovanni — was the dominant painter in Siena during the first half of the fifteenth century, maintaining the city's Gothic tradition of refined spirituality and jewel-like color even as Florentine artists were developing the naturalistic revolution of the Early Renaissance.

The predella scene demonstrates Sassetta's gift for architectural space and narrative drama, with the prison setting rendered in convincing perspective and the figures arranged to convey both the miraculous event and human emotion.
