 This depiction tends to merge into one of "Christ the teacher", which also derives from classical images of bearded philosophers.Other Imperial depictions of Christ, standing as a triumphing general, or seated on a ball representing the world, or with different companions, are found in the next centuries.By the seventh century the Byzantine Christ Pantocrator holding a book representing the Gospels and raising his right hand has become essentially fixed in the form it retains in Eastern Orthodoxy today.
