Byzantin (Byzantine)

The art of the Byzantine or Eastern Roman Empire (with capital Byzantium or Constantinopel) which existed from 330 to 1453.
Although a personal guess, I would not be surprised if the artists who made this peinture murale (mural) in the Notre-Dame-de-l'Assumption in Gourdon were influenced or inspired by the depictions of Christ Pantocrator, a popular motif in Byzantine art.
