Sixtus IV appoints Bartolomeo Platina prefect of the Vatican Library Melozzo da Forli (1438-1494)

The composition presents a formal scene unfolding within a grand architectural setting. Here we observe a central figure seated on an elaborate throne, distinguished by his papal vestments – a white cassock and crimson mozzetta – and the presence of a mitre. He appears to be presiding over a ceremony or appointment.
To his right stands a man in red robes who seems to be receiving some form of official documentation from the pontiff. The gesture of extending his hand towards the seated figure suggests acceptance or acknowledgement of this bestowal. Flanking him are three other men, each dressed in varying degrees of formality; one wears a dark cloak and cap, another a simple tunic, and the third is clad in a more refined doublet. Their postures suggest attentiveness and respect for the proceedings.
The architectural backdrop is highly structured, with arched niches containing sculpted figures and an ornate coffered ceiling that draws the eye upwards. The walls are adorned with decorative panels featuring intricate patterns of blue and white. This elaborate setting underscores the solemnity and importance of the event depicted. A band of Latin text runs along the bottom edge of the painting, likely providing a scriptural reference or explanatory inscription related to the scene’s significance.
The arrangement of figures creates a clear hierarchy, with the seated figure commanding the most visual weight and signifying authority. The use of light emphasizes his presence and directs attention towards the central action. The overall impression is one of institutional power, religious ceremony, and the formal transfer of responsibility within a hierarchical structure. The subdued color palette, dominated by reds, whites, and browns, contributes to a sense of gravitas and tradition.
