Acts 9: 18 – 19
He (Saul) got up and was baptized, and after taking some food, he regained his strength.
Saul, Ananias, and the witness, now holding a basin, have stepped outside of the portico. The sky is now more visible, filing most of the upper third of the fresco. Ananias has taken his cloak to cover his head. Saul has placed his sword on the ground. Saul kneels with his head lowered and hands placed in a prayerful position. Ananias raises his left hand with a curving gesture toward heaven, while he pours the water of baptism from a cup with his right hand. Saul’s feet, thighs, back and neck form an S-curve which lead our eyes up to Ananias’ thick, forked beard and bowed head. If you follow the curve of both of his arms, he could be hold a near perfect sphere.
The unity of baptism is evident in the implied geometry. The Greeks would have been all over this. The implication, again, is Paul’s missions to the Gentiles, which will include many stops in Greek influenced regions and cities. Hence, all those letters Paul will write to the chuches in Galatia, Ephesus, Colosse, Corinth, Philippi, and Thessalonia.
