This small, inconspicuous 9th-century church is known above all for the exquisite Cappella di San Zenone, just to the left of the entrance. It gleams with vivid mosaics that reflect their Byzantine inspiration. Though much less classical and naturalistic than the earlier mosaics of Santa Pudenziana, they are no less splendid, and the composition of four angels hovering on the sky-blue vault is one of the masterstrokes of Byzantine art. Note the square halo over the head of Theodora, mother of St. Pasquale I, the pope who built this church. It indicates that she was still alive when she was depicted by the artist. The chapel also contains one curious relic: a miniature pillar, supposedly part of the column at which Christ was flogged during the Passion. It was brought to Rome in the 13th century. Over the main altar, the magnificent mosaics on the arch and apse are also in rigid Byzantine style. In them, Pope Pasquale I wears the square halo of the living and holds a model of his church.
