They called them Constellations. A Constellationis a group of stars visibly related to form a specific configuration. In 3 dimension, most of stars that we observed haven’t onerelation to other. The Late Latin term constellation can be translated as "set of stars".Since stars travel on their own orbits through their galaxy, constellations change slowly and can even disappear. This takes tens of thousands of years.
