How did the constellations get their names?

The present names of the constellations are given, in most countries, in Latin. The names have come to us from classic Greek civilization, which, in turn, took them from earlier sources. Some names have been given to various groups of stars by modern astronomers.
Every ancient civilization had its own names for various groups of stars. The Babylonian constellations were, for most part, much larger than the present constellations. The Babylonians, Egyptians, Arabs and Greeks have given names of the constellations. In many cases, a group of constellations are associated in Greek mythology. For example, the Perseus-Andromeda group, and it is difficult to tell whether the myth or the constellation came first. In many cases constellations had the same name in the languages of several ancient cultures. The Greeks and the American Indians all called the stars Ursa Major, "The Bear". The first catalogue of the constellations was Ptolemy's catalogue. Ptolemy listed 48 constellations. Ptolemy's constellations did not cover all the sky. There were gaps between groups of stars. Such spaces Ptolemy left blank. Ptolemy listed 108 stars.
Astronomers of the sixteenth and seventeenth centuries used some of Ptolemy's "unformed" stars as a basis for new constellations to fill in the vacant areas.
The 88 modern constellations contain 15 men and women, one head of hair, 9 birds, one insect, 22 land animals, 10 water living things, one serpent and 30 inanimate objects.
