A nineteenth-century albumen silver print by Fratelli Alinari, documenting the fourteenth-century fresco of Saint Renier by Andrea da Firenze in Pisa.

This albumen silver print by the Fratelli Alinari firm captures a photographic record of the fourteenth-century fresco cycle located within the Camposanto Monumentale in Pisa. The original work, attributed to the Florentine painter Andrea da Firenze, depicts the life of Saint Renier of Pisa. The scene focuses on the moment Renier receives the hermit's habit, a narrative episode central to his hagiography.

Andrea da Firenze, active during the mid-to-late fourteenth century, is known for his contributions to the Spanish Chapel in Santa Maria Novella. His style in the Camposanto frescoes reflects the transition from the Trecento tradition toward more complex spatial arrangements. The composition is divided into distinct narrative zones, typical of medieval storytelling, where multiple stages of the saint's conversion are presented within a single architectural frame. The figures are rendered with the linear clarity characteristic of the period, prioritising the legibility of the religious narrative over naturalistic depth.

The Alinari brothers, pioneers in the field of photographic documentation, produced this image as part of their extensive project to catalogue Italian art history. By employing the albumen process, they achieved a tonal range that preserves the subtle gradations of the original fresco, even as the physical condition of the wall painting shows signs of age and environmental wear. The print serves as a historical document of the fresco's state during the nineteenth century, capturing the decorative borders and the architectural context of the Camposanto walls. The image provides a clear view of the iconographic details, including the figures of the monks and the symbolic garments, which remain essential for the study of Pisan religious art.
