Constellation is an indispensable part of astrology and a group of stars in the sky. Since ancient times, human beings have associated three or five stars with their mythical figures or artifacts, which are called "constellations".

Constellation is a means to determine the orientation of the sky in almost all civilizations and is widely used in the field of navigation. The division of constellations is completely artificial, and different civilizations have different divisions and names.

In 270 BC, the Greek poet Aratus wrote Things, in which 47 constellations were mentioned. From the star regions recorded in Celestial Bodies, we can know that due to precession, the South Pole in the period described in the book is not consistent with the current South Pole, so it can be inferred that the starry sky recorded in the book is before 2000 BC.
