The Teaching Christ with Paul and Peter Acclaiming Him

4th century sarcophagus fragment
Pio-Christian Museum, The Vatican, Rome

The throne itself is unseen, but as in most enthronement images we see the cushion and the footstool. Paul is on the left with his long beard and receding hairline, holding a scroll in his left hand. Peter, also with a scroll, has the usual short, square beard.

In this early image, we do not yet see the keys and sword that will be the two saints' attributes, nor is a cross inscribed on Christ's halo. Through the centuries the book will often re-appear in images of this type.

It is hard to tell which fingers of Christ's right hand are which, but if the thumb is touching the fourth finger (the one next to the pinky) this would be the gesture seen in a number of later such images, expressing either blessing or the beginning of an instruction (or both).
