Where does the constellation come from _ What does the constellation appear?

This constellation was invented by ancient Babylonians.

Western constellations originated in Babylon, one of the four ancient civilizations. The original Babylonians made a star chart of the four seasons according to the stars, hoping to use it to predict the fate of the country and people.

In fact, this method of divination is similar to that of ancient China. It is based on the relationship between the fortune teller and the stars and explains all aspects of his life.

Since then, the Babylonians have continued to divide the sky into many regions and put forward new constellations. Around 1000 BC, 30 constellations have been proposed. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table.

In the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. Connect the main bright stars in the constellation with imaginary lines, imagine them as images of animals or characters, and give them appropriate names in combination with fairy tales. This is the origin of the constellation name.
