Just to be fair to all, the Serbs have been painting “Ancient of Days” “icons” since the mid 13th century. :)
As for we Greeks, well, I was looking at one on our iconostasion just this morning during the liturgy and there is one in the Pantanassa monastery at Mystras, the now abandoned (save for 5 or 6 nuns)seat of the Byzantine Despot of Morea, not far from my maternal village. The monastery was built in 1428 (the last building constructed under the Despotate) and the body of the first wife of Constantine Paleologos, the last emperor of the Eastern Roman Empire, is buried there.
Oh, absolutely! But not just the Serbs. They merely copied what they learned from the Greeks. :)
"Ancient of Days" show Christ as the (old and gray) Father (LOL, talk about heresy!), that is before he "became" the Son...oy! And all this in churches proclaiming orthodoxy!
