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 (the Pleiades was considered as an independent constellation at that time, not a part of Taurus), and at the same time, Babylon had 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.
