No Stupid Questions

Hi. I'm an artist, and my answer comes from my personal experience and not from academic research on your topic.

Turns out painting and sculpture pose different challenges to artists. If your goal is realism, you first need to understand your subject, and then you need to translate it to the medium.

One key aspect in the process is finding good reference material to work from. Turns out human faces and bodies occupy three dimensional space, and they are somewhat readily accessible to artists. A talented sculptor can study a model and replicate it as a sculpture; it's not easy, but there isn't much else to be done.

Now let's look at painting. Often people think painting and drawing is easier than sculpting because it's more accessible, but that's not necessarily the case especially if you aim for realism. The artist needs to use the brain and translate a lot, and I mean an awful lot, of the information seen in the model (3d space) into 2d. They need to remove one dimension from it, without breaking the illusion. This is why it's ten times more difficult to sketch from life than it is to sketch from photographic reference; photos already did half the job for you. And back in the day photography wasn't a thing.

This is very hard already, but on top of that comes color. Most people can see color well enough, the difficult part is understanding how to translate that to a flat, uniform surface that doesn't emit light. From the get go this means you will have to crunch down and remove color information, ie you can't paint the sun and expect it to shine like the real thing, instead you will have to either make everything else too dark or not paint the sun just to keep the lighting relationships making sense. Your brain has evolved to see color shades, to take into account lighting conditions and contrast and a lot of other things. And yet, you hardly realize you are seeing all these things because what matters to you is what color things are meant to be, not what color things really are in a myriad of lighting conditions. In other words, you don't have a color picker tool ability that lets you easily replicate any color you see. This takes years of training.

Then as if this alone wasn't difficult enough, you now have to deal with pigment chemistry and colors that dry different shades, incompatible or unstable pigment combinations, hard to find pigments, etc. These issues still have to be taken into consideration today, but in the past even more so since people had a lot less options available for a variety of reasons.

I hope by now you're getting the idea that you have far far more opportunities to botch a painting than a sculpture. Take any civilization and with a few generations of skilled sculptors passing on the tricks of the trade you can reach realistic results. But it took centuries and a lot of thinking and writing and studying to start achieving realistic painting standards. I'm not surprised at all.

Realism wasn't necessarily the end goal of a lot of painting. When you look at old Christian art one thing to notice is that different people can have vastly different sizes. The virgin mother may be most prominent, some patron saint smaller, and the artist themselves or the commissioner may be included as smaller figures. This play of scale was a device to show what was important and being sure to capture and portray that hierarchy was a more important goal than realism.

Take a look at this:

This is in the Museum of the Palazzo Massimo alle Terme in Rome, and it comes from an ancient Roman Villa in Rome. Probably painted in the first or second century CE. There's walls of this stuff in the museum.

It's not realism, but minimalistic sketches that, in many ways, outdo realism in artistic quality. To me, this looks more like something that you might find in Leonardo's sketchbook than on the wall of on ancient Roman Villa from 1200 years earlier.

Art isn't a progression. "Realism" isn't necessarily a goal.

If capturing some subject in the most naturalistic way possible was the goal of art, there would be no need for paintings after the invention of the camera, and sculpture would be obsolete because of 3d scanning. Art must be something beyond capturing nature, otherwise there would be no reason for humans to do it.

Culture mainly. Same reason why some artists today draw photorealistic drawings and others draw more cartoony. You don't need to draw or sculpt something to be hyper-realistic to explore the abstract nature of art.

THE PROPER TOOLS.

YOU try scrawling on a cave wall with nothing but the charcoaled end of a stick you pulled out of a fire and see how well you can draw with that kind of medium and tools.

As technology progressed, so did the tools used.

Michelangelo was using a fresco technique painting onto still wet plaster and used egg whites or glue made from animals to help the paint stick. He used a variety of brushes, not just a charcoal stick.

Further, just something as simple as a variety of colors took hundreds of years of technological advancement to achieve.

Don't underestimate the need for quality tools!

First reason is the knowledge and understanding to paint like this has come and gone. We have paintings from Egypt from 100 BC that is very realistic. They are known as the Fayyum portraits.

Also, paint isn't the most long lasting of materials, so less painted anything still survives. While many don't know about it, but Greek and Roman statues were painted.

I literally just saw a video on cave paintings the other day and one of the oldest set of cave drawings ever found in France (dating almost 14,000 years ago) are some of the most detailed, and realistic depictions of animals in artwork I've seen.

I don't think it took long to be realistic. It started realistic and evolved into stylization. And then looped back to realistic being cool again.

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.

Art supplies were historically not cheap. If you wanted to do this for a living, you were probably needing to aim for selling your art to the rich upper class. That implicitly meant catering to their fickle tastes and working on commission. You didn't make art for you and find your audience later, you made art for the customers you had or you starved.

And to put it bluntly, realism wasn't the fashionable hotness for most of human history. The more "crude" styles you may think of as objectively inferior to and less technically impressive as realism were in fact the styles in demand at their respective times. Fashion existed in ancient and medeival times just like it does today, and those styles were the fashion.

The idea of the independent eccentric artist who lives secluded in their ideas cave producing masterpieces for no one in particular leaving the world in awe at their genius every time they come out with something to show is a very modern concept. If any artist wanted to make a realism painting in an era where it was not popular, they'd be doing it purely for themselves at their own expense. So virtually no one did. Or if they did, their works largely didn't survive.

Nuh-uh, people have been painting realistic pictures for wayy longer than that.

Here's a Roman painting circa 40 BC.

This is from about 600-something AD.

12th or 13th century AD.

Also I think that possibly photograph-like realism may just not have been something artists aimed for, so they just created other styles that the next generation of artists learned to copy, and repeated that until someone came up with a new style.

Materials.

If you'd have seen the marble sculptures when they were new, you would have described them as anything but realistic. We now know that many, if not most, sculptures were painted in bright garish colours.

Why paint a delicately crafted sculpture with a dodgy paint job? Party taste, perhaps, but more definitely because that was what was available.

The paints that we have now are carefully designed, mixed and stored to deliver a wide range of colours of a consistent quality (and even modern companies like GW struggle with that!).

The further back you go, the fewer pigments there are and the less sophisticated the binders are. It's no coincidence that the rapid explosion in science and trade of the Renaissance led to the rapid development of paints. Even in those days, an artist didn't buy paint, they made it - access to new raw ingredients was all that was needed.

So, why the Renaissance? Because it's the earliest point in time it could have been possible.

I'm not an expert on the subject, but i didn't see anyone else mention time as a factor. For a long time humans were simply too busy trying to survive. Once civilizations started coming around along with extremely wealthy and powerful people, then more time for leisure, art, and science came. Some of the extremely wealthy people of the past hired artists, mathematicians, scientists, musicians, etc to just live with them and study full time. The expectation was that they would share their work.

We're also looking at the art that survived until today. It's not like we have libraries full of art from every culture.

Tastes have changed.

Your judgement is different from their judgement.

What you are calling 'realistic' probably did not even exist then, and nobody missed it.

Requires knowledge of geometry and that shot is hard. Perspective lines and angles and etc.

Just to add another factor to the ongoing discussion: artistic talent isn't uniform and never was. Just because only/mostly "immature" art survived from a certain century of human history, doesn't mean that there literally was no realistic art present at the time. Since you mentioned the statues already...

These are from the same era (around 200 BC), but as you may have guessed, made by different artists =P The statue is called The Dying Gaul by the way.

As for painting examples, I guess the Rothschild Canticles^1 book illustrations represent best what most people nowadays would call medieval art. Not exactly realistic, a little goofy ... perspective? Never heard of it. Proportions? Who cares. And who needs shading anyway?! As long as you can still distinguish a human from a cupcake, it's "eh good enough".

I guess that was also what you meant by "immature" art, because it is the same art style as those goofy weird pictures of knights fighting giant snails and rabbits riding cattle into battle and the like.[^2]

That book is dated to be around 1500–1520 so it would be easy to assume that people at the start of the 15th century didn't have a realistic art style yet. But you know what else was made in that same era?

The Mona Lisa (1503–1506).

One dorky meme-esque style, and one realistic, modest and easy-on-the-eyes style in the same century, probably even the same decade. But they were used by different artists.

Now you might be thinking that those art styles might have been intended for their respective purpose or something along the lines: that the goofy, simple art style was used for nothing but amusing little pictures, and the more realistic style was for "proper" art, because noone in their right mind would spend 100+ hours painting highly detailed nonsense just for sh*ts and giggles, right?

May I introduce you to Joseph Ducreux?[^3]

I guess most of you will have seen that meme by now, but this is a real painting made by a real artist - and it is far from the only one. Ducreux created an entire series of similar self-portraits in ... unusual poses and situations.

... so yes, at least that one guy DID indeed spend dozens if not hundreds of hours (plus material costs) painting amusing nonsense for his own entertainement. He was, in a way, the victorian era equivalent of a shitposter (and I mean that in a good sense!)

Long story short: one can't just claim that "they didn't have X art style in Y century" because the truth is much more facetted than that. It is way more likely that each and every era of human history has had people with insane talent who were able to create art as realistic as possible with whatever tools their lifetime had to offer, and also a bunch of "eh good enough" art or stuff that was deliberately stylized for fun. How we percieve said art today depends mainly on what artworks have survived up until now, and/or how popular the surviving art is. (Everyone and their grandma knows about the Mona Lisa, but how many of y'all knew about the Rothschild Canticles?)

If we don't know about any realistic art from a certain period of time, it doesn't automatically mean that there was no realistic art. It may have been lost, forgotten or it exists but it's just not popular enough to be well-known.
