The legend of Sagittarius:

In ancient times, there lived a half-man, half-beast ethnic group-Sagittarius on the Greek prairie. Sagittarius is fierce, with a humanoid upper body and a horse-shaped lower body, representing the contradiction between human nature and animal nature.

Chilon is an exception in Sagittarius. Chilon is also a member of Sagittarius, but he is not as cruel as other tribal members. Chilon is more human, gentle and kind. Chilon is very kind to his friends, frank and honest, and is highly respected in the tribe.

One day, the hero of mankind, He Qiuli, came to Sagittarius to visit his friends. He Qiuli heard that the wine brewed by Sagittarius was delicious, so he forced his friend to steal it for him to drink. Although this friend is also a member of Sagittarius, he is still a little scared in the face of He Qiuli's powerful brute force, so he has to obey his orders and steal wine for He Qiuli to drink.

He Qiuli is very satisfied with the good wine of Sagittarius. The more he drank, the more fragrant the wine became, and it spread all over the tribe. Sagittarius members are very angry about the taste of this wine, and they reprimanded Qiu Li's behavior together. Of course, He Qiuli's arrogant personality can't stand it, so he took up his own weapon to hunt down Sagittarius members. The troops couldn't beat Qiu Li, so they fled hastily and fled to Chilon's door for help.

Chilon heard shouting ShaSheng and cry for help outside, immediately opened the door and rushed out. At the moment Chilon opened the door, He Qiuli's bow was just full, and an arrow shot out, just stabbing Chilon's heart. Good Chilon died to save a friend.

Sagittarius companions were very sad when they saw that Chilon was innocent and lost his life. They cried loudly. Zeus, the god of gods, heard the cry of Sagittarius and was very moved. He threw Chilon's body into the sky, and Chilon became countless stars, which looked like Sagittarius. This is Sagittarius, also called Sagittarius.

Extended data

The origin of western constellations:

In 270 BC, the Greek poet Aratus wrote Things, in which 47 constellations were mentioned. According to the star regions recorded in Celestial Bodies, due to precession, the Antarctic in the period described in the book is not consistent with the current Antarctic, so it can be inferred that the starry sky recorded in the book is before 2000 BC; At the same time, the blank area of the starry sky record indicates that the observer should be near 35 to 36 north latitude.

So some people think that the practice of dividing the starry sky into constellations originated from Babylon and Sumer in Mesopotamia, and the constellations of Greece and Egypt may have been introduced from this area.

In the Book of Job, several constellations such as Bear and Orion are mentioned. In the12nd century BC, the land landmarks built in the era of Nebuchadnezzar I were engraved with designs of Sagittarius, Scorpio and Ophiuchus. The ancient Greek poets Homer and hesiod also mentioned Ursa major, Orion and the Pleiades, while at the same time, Babylon recorded the zodiac in cuneiform.

In the second century, Ptolemy recorded 1022 stars in 48 constellations in his astronomical masterpiece, which is also the embryonic form of modern constellations. After that, many astronomers filled the Ptolemaic constellation with new constellations. Valle in 1603, Jahannes Hewelius in 1690, and Llakaj in 1752 have named the constellations in Nantian in two centuries.
