What was the aim of the Byzantine mosaic shift to abstraction?

[Zachary.P]

I’m trying to understand the shift in Byzantine mosaic work from the earlier, more naturalistic figures to the later, much more abstract and symbolic style. I was looking at the mosaics in the Hagia Sophia compared to some in Ravenna, and the flattening of form and the use of gold tesserae to create that overwhelming spiritual effect is so pronounced. I just can’t quite grasp what the artistic or theological intention was behind abandoning that last bit of classical illusionism.

Interesting boundary you’re tracing. The shift after the early naturalism feels tied to theology as much as to technique. In Hagia Sophia the space is about a single divine presence filling everything, not about modeling a body. The gold tesserae catch light and bend it into an otherworldly glow, so the figures look less like people and more like signs of heaven. People describe it as flattening and elongation, but I hear it as a move toward spiritual visibility rather than anatomical truth.

I've stood in Ravenna halls and tried to map why the faces end up with simpler cues. The light and the wall planes do a lot of the work; the figures are silhouettes that keep you from reading personality into them. The effect feels like a curtain rising—glittering background, blue and gold in the shade, and the viewer is pulled toward the conjoined space rather than a single sitter.

Could it be that the real issue isn't whether the figures read as human, but whether the space itself wants to erase illusion in favor of a liturgical sense? In Hagia Sophia the architecture makes you feel you are inside a lit icon, so the art serves the rite more than the life of a person?

Another thing that stuck with me is the craft grind—the tiny stones, the mortar, the patience. I tried to replicate a patch of gold light with colored bits, and it looked flat until the light angle shifted; then it felt like it might catch a child’s eye more than a scholar’s. It’s not a tidy theory, just a memory of the hours and glimpses.
