Who created the constellation _ Who created the constellation?

More than 2,000 years ago, the Greek astronomer Baccus (190 ~ 120 BC) divided the ecliptic into twelve segments, with the spring divided into zero, and every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic) as a palace, and named it after the main constellations contained in each palace at that time. Babies born when the earth moves to every bisector (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics and personality characteristics. Connect these associations (rich imagination and creativity) in series to make the humanity of these constellations concrete; Coupled with the color of myth, the twelve constellations have become an important part of ancient Greek culture.
