Who invented the head of the zodiac _ Who invented the head of the zodiac?

It was not until the 2nd century A.D. that an astronomer named Polemius in Alexandria systematically arranged the constellations handed down from Greece into 48 constellations in his book Astronomy Highlights, totaling 10 10 stars, and he drew these constellations into a constellation map. The 48 constellations set by "Polemes" took more than 1000 years. In the15th century, navigation technology advanced by leaps and bounds, and European explorers crossed the equator and sailed to the southern hemisphere. Only then did they find that the stars in the southern sky could not be found on the constellation diagram of "Polemes", which brought great inconvenience and trouble to the navigators. Thus, from15th century to19th century, astronomers all over the world, with the help of precise observation instruments, not only divided the stars in the south into constellations according to their positions, but also observed many new constellations in the northern sky. However, due to the different constellations divided by each astronomer, the constellations produced are also different, which brings inconvenience to navigators and greatly affects the progress and development of astronomy. 1922, the international astronomical union thought it necessary to unify the division of constellations, so it established the Constellation Committee. By 1930, the Constellation Committee divided the main stars visible to the naked eye all day into 88 constellations by region. Among them, 29 are in the north of the ecliptic, 46 are in the south of the ecliptic, and 13 crosses the north and south of the ecliptic (one Ophiuchus has been neglected for a long time and is controversial at present). Definition of the ecliptic: a great circle extending the intersection of the earth's orbital plane and the celestial sphere. The Babylonians believed that the sun circled the constellation once a year. Before sunrise or after sunset, when the sun is dim, observe the surrounding stars and form a ring called the ecliptic. The yellow star is divided into 12 constellation, which is called "Zodiac", that is, 1. Mutton Palace (also known as Aries Palace) 2. Taurus Palace 3. Twin uterus 4. Cancer Palace 5. Lion Palace 6. Virgo Palace (also known as Virgo Palace) 7. Libra 8. Scorpio Palace (also known as Scorpio Palace)
