Who invented the twelve constellations? The origin of constellation theory

The Origin of Constellation Theory Constellation originated in Babylon, one of the four ancient civilizations. Babylonians put forward 30 constellations around 1000 BC. The Tigris River and the Euphrates River flow from northwest to southeast and into the Persian Gulf, so they are also called the two river basin areas. After the culture of the two river basins spread to ancient Greece, it promoted the cultural development of ancient Greece. 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. After the Middle Ages, European capitalism rose and needed to expand outward, and the navigation industry was greatly developed. Ships sailing at sea need navigation at any time, and stars are the best street lamps. Among the stars, this constellation has a special shape and is the easiest to observe. Therefore, constellations have aroused widespread concern. 16 when Magellan actually sailed around the world, he not only used constellations to navigate and orient, but also studied constellations. 1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations, and their names basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12. And the constellation we usually say is the 12 constellation on the ecliptic. Each of them has some myths and legends about himself. Constellation originated in Babylon, one of the four ancient civilizations. The Babylonians divided the sky into many regions and called them constellations, but at that time constellations were of little use and were rarely found and named. The constellation 12 on the ecliptic was originally used to measure time, not to express people's character as it is now. 1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations, and their names basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere, 47 in the southern hemisphere, and near the equator and ecliptic 12. The constellations in astrology are just like some peoples in East Asia who define a person's zodiac according to the animals represented by the year of birth. In many countries, a person's birth month corresponds to the constellation. Birth constellation comes from astrology, trying to explain people's character and destiny by using their birthplace, birth time and celestial position.
