I mean, you take one look at Greek statues and Roman busts and you realize that people figured how to aim for realism, at least when it came to the human body and faces, over 2000 years ago.
Yet, unlike sculpture, paintings and drawings remained, uh, “immature” for centuries afterwards (to my limited knowledge, it was the Italian Renaissance that started making realistic paintings). Why?
I do find it interesting that folk think Renaissance art is realistic.
I’m being a little glib, but the truth is that we are still looking at hyper-idealised bodies.
The main difference,I suspect, is the use of perspective rather than drawing on a flat plane. In a way it took a leap of imagination to make things look more “realistic” whilst sculpture was merely (again, said with a certain smirk) just mimicking what the artist could see and feel in the real world.
That is to say that sculpture is reproduction whilst drawing is representation, and with representation you need to be able to take some pretty big leaps for both the artist and the viewer to work these things out.
I actually was fortunate enough to visit the Sistine Chapel this summer, and although when you take a close look at images online of the paintings, it’s clear they aren’t “realism”, when you see the paintings in person they look very real. I was especially struck by how real Jonah looked, as if he was just hanging out, sitting on a ledge near the ceiling. Very cool experience.
