Pope Paschal I built the San Zeno chapel at Santa Prassede as a funerary chapel for his mother Theodora. Its exceptionally rich mosaics were created during his pontificate, AD 817–824.
The vault centers on a medallion of Christ held aloft by four angels. The compact, symmetrical arrangement and gleaming tesserae turn the ceiling into a vision of heavenly glory. Supplementary photographs help reveal the surrounding decoration.
Christ’s image at the center of the vault communicates heavenly rule and the hope of salvation. In a funerary chapel, this imagery also expressed confidence in the resurrection.
The chapel is among the most complete surviving early medieval mosaic interiors in Rome. It provides unusually rich evidence for a coherent ninth-century decorative program.
The medallion portrait of Christ and surrounding angels belongs to a long Christian visual tradition that continued in medieval vaults and domes.
