What do geometric patterns in painted pottery decorative patterns mean?

Look at the decorative patterns of painted pottery, which are mostly abstract geometric patterns. Besides expressing visual effects, these patterns should also have their own meanings. Primitive people's persistent love for these patterns must have the function of expressing some thoughts, which attracted many scholars to explore and study and draw various explanations.

The evidence provided by archaeologists that some geometric patterns in Banpo painted pottery evolved from fish patterns is very convincing. The enlightenment from this proves that many geometric patterns are realistic descriptions of some animals, natural objects and even tools, and then gradually evolve into abstract geometric patterns. Such as the bird pattern in Miaogou. The evidence of this transformation from realism to abstraction and from content to form can be found in frog patterns of Machang-style human bodies, as well as various fire patterns and water ripples. This change may take a long time. There seem to be two starting points for describing these animals and natural objects. One is that they are of great significance in human labor and life, and become the main food for people to survive, such as fish, birds, frogs and so on. Fishing nets and stone tools are tools for predation, so it is understandable that people first show these things after survival. Similarly, water gives life on weekdays and death when it overflows. Many water ripples in painted pottery patterns are people's feelings for water. Another starting point seems to have a deeper understanding of the problem. Starting with the cognition and religion of primitive people, it thinks that the meaning of description is not all in these animals and natural objects themselves, but other meanings associated with these things, which is a reflection of primitive religion. For example, the description of fish, birds and frogs is people's natural yearning for fish swimming in the water, birds flying in the sky and frogs living an amphibious life in production activities. Then, for a large number of water ripples and vortex ripples, it is not considered to be the performance of water, but originated from the worship of snakes. These patterns are simulations of snakes crawling and circling, and snakes will become the main body of future dragons.
