There's also been that story about a man who has grown up without ever seeing a painting or a drawing and was one day confronted with an image of a horse. Yet, though he has seen a horse before, he could not identify the image on the paper as being a horse simply because he could not walk around it and touch it.
So our relationship, especially how and why it began, with 2-dimensional art is a mystery. Still, ever since that time when we first decided to stencil our hand on the ceiling of a cave, we have continued to nurture our newly found ability and found a suitable media for it: painting.
Now, cave paintings, as said before, started around 32,000 years ago, meaning ~30,000 B.C.E. The materials used were usually charcoal or red ochre combined with some sort of binding. It would then be applied with some sort of brush or the paint was put inside a persons mouth and spat out at the surface of the rock.
The images that were typically made were of animals (bison, deer, etc), stencils of human hands, odd patterns of dots, and even images of humans, sometimes with body parts of other animals.
People have been trying for a long time to figure out why these images were made. These drawings were generally found in caves and would also often be found in difficult to get to, claustrophobic areas of said caves. That means that while the images were out in public, they were not necessarily made as decoration of a living area or for display.
With the reason more associated with modern art ruled out, some have theorized that the drawings served as something of a prayer. The idea is that the people would draw images of animals in hopes that the images would bring good luck when they went hunting the animals depicted. Yet what goes unexplained by this theory are the odd patterns of dots and the images of the half human half animals.
The other theory is that these paintings were part of a ritual in which a person, a shaman per se, would enter a trance in order to heal another member of the tribe. What was often seen in these trances would be those odd patterns and, what they likely saw, were the animals as the animals were culturally a significant part of the tribal life. So the images would then be depictions of what the person saw when in a trance.
The next big thing in painting after cave paintings was fresco. Fresco painting has a long tradition that dates back into the Greco-Roman era (as pictured above) and has continued to be popular during the Byzantine empire, the Renaissance, and Baroque art. Fresco is even still used today, though not quite as prolifically.
Fresco is the practice of painting on plaster. There are actually several ways you can fresco paint. True fresco, more commonly known as buon fresco, or dry fresco. Buon fresco is the technique of painting on wet plaster. This means you have to work very quickly and does not allow much margin for error. However, the finished piece lasts far longer than dry fresco. Dry fresco is the technique of painting on dry plaster. It allows for a longer working time frame, but the finished piece is less likely to last.
What this also means is that a person needed a higher amount of skill in drawing realistically. So ateliers were created in which there was a master painter who received commissions from his patrons and then there were apprentices which would help out with the painting of said commissions. Back in the 1500's, apprentices generally had to live with the master painter which meant that women were unable to become artists unless their father was one and was willing to teach them. On that note, there have been a few woman painters in the past, most notably Artemisia Gentileschi and Angelica Kaufmann.
