What theories exist about why the elegance and realism of art seemed to degrade sometimes? 

Like, the cave paintings are very minimalistic, but the humans and animals are depicted with more livelihood and grace than on the clumsy Medieval images. Or, the famous Egyptian art has totally unrealistic torso posture, but still prevails over the Medieval in the detail, proportions and composition?<|im_end|>

The progression of artistic style isn't necessarily a straight line towards greater realism, but rather reflects changing cultural, philosophical, and religious views of different societies at different times. Each style of art carries its own intention and context, and what may appear as regression or clumsiness can often be a shift in artistic focus and values, rather than a decline in skill or understanding.

- Prehistoric Art - The Lascaux Cave Paintings display a remarkable understanding of animal forms, and the artists employed sophisticated techniques like perspective and shading. The focus was on capturing the spirit and essence of the animals, which were central to their survival and religious beliefs.

- Egyptian Art - The seemingly 'unrealistic' style of Egyptian art is due to their artistic conventions and symbolism. They used a composite view for human figures: head in profile, full-frontal eye, and torsos twisted halfway between front and profile view. This wasn't due to a lack of understanding of perspective, but rather a symbolic representation, designed to depict each part of the body as clearly and recognizably as possible.

- Medieval Art - The seemingly 'clumsy' figures in Medieval art were again a reflection of the values and beliefs of the time. The focus was on the spiritual and the divine, rather than the physical world, so figures were often stylized and abstracted, rather than naturalistic. The goal was to represent theological truths and narratives rather than realistic human figures.<|im_end|>
