The early anatomy and perspective were excellent. It was a conscious desire to replace perspective and anatomical detail with Christian symbolism that changed art drastically. And that lasted for centuries until they “rediscovered” perspective. That’s not putting down Christianity. That’s just observing how it affected art styles. (Very old U of Chicago Art History major)

Thanks...I never knew that. I always wondered why the human figure was so poorly done.
Being an engineer, I stayed away from the arts which I regret.
I think this was true of a lot of Egyptian art as well. They depicted things in the stylized way that they did for philosophical/religious reasons, not simply because they couldn’t master realistic perspective.
