Who introdous the oldest descriptionof the constellation?
The first constellations were, we believe, invented by the ancient Babylonians and Sumerians, and perhaps the Phoenicians. These were to give people a way to refer to the stars and constellations, and provided a heavenly anchor for their stories. Most of the northern hemisphere constellation names that we use today were invented, or adapted, by the ancient Greeks and Romans. The southern hemisphere constellations were largely named by sailors and mariners.
