The origin of constellations

Mesopotamian astrologers divided the starry sky into several regions for the convenience of studying and observing many stars in the sky, and each region was a constellation. It's hard to say clearly when humans began to have the concept of constellation. This astronomical knowledge was known long before there was a historical record. The name of the constellation probably comes from the sailors who sailed early.

The origin of constellations may be completely different between civilizations in different regions, but with the expansion and mutual influence of civilizations, the culture of constellations also includes the process of integration.

In ancient China, Sanyuan, which is near the North Pole, was defined as a middle official, while Erbasu was actually subdivided from four elephants. The star area south of Erbasu was called a foreign official, that is, "middle official+four elephants+foreign officials", which was just one of the many ways to divide the star areas in ancient China.

In addition, there are many ways to divide the stars into seven areas, such as "five beasts+middle officials+foreign officials" and "nine wild+middle officials+foreign officials" which are divided into 1 1 area, but the division method of "middle officials+four elephants" is widely spread.

There are different opinions about the order in which the starry sky is divided into three walls, four images and twenty-eight nights. Gaul, an astronomer in the Republic of China, thought in his book Notes on Astrology that three walls appeared first, then four elephants, and finally appeared for 28 nights.

Chen Zungui, an astronomer who was the first curator of the Beijing Planetarium, thinks in his works that these four images appeared earlier, and then they were divided into twenty-eight lodges, with Sanyuan being the last one, and points out that the name of Sanyuan only appeared in the Song of Dan Deng Tian in the Sui Dynasty, and the shape of Sanyuan and Twenty-eight lodges was also formed and used here.
