The mosaic depicts Christ Pantocrator, the Almighty, in a scene out of Revelation 4. He is pointing with two fingers, a Nicene symbol of Jesus’ two natures. The apostles sit on either side of Him, while the four creatures representing possibly the four evangelists (angel, lion, ox, eagle) hover above the scene. The twelve apostles, two of whose images in the mosaic were lost over the years, sit at the table on both sides of Christ, who is centered. They all gesture among themselves, while two women, Prassede (Praxedes) and Pudenziana (Pudentiana), one on either side of Christ, hold crowns over the heads of the two closest to Christ. The bearded men are dressed in the toga, senatorial dress. Christ himself is on an ornate throne.
