These mosaics portray a number of people, some of whom are identified. The name of Pope Paschal I’s mother, Theodora, was written in the mosaics in this chapel by her portrait, followed by the title, episcopa. While an exact meaning cannot be determined, this title typically referred to the office of bishop.
In the fifth century, the priest Peter Illyria built the Santa Sabina Basilica in Rome over a former house church. Above the door of the main entrance there is a mosaic portraying two women: one is identified as representing the church of the circumcised and the other as representing the church of the Gentiles.
