The Oldest Lunar Calendars and Earliest Constellations have been identified in cave art found in France and Germany. The astronomer-priests of these late Upper Paleolithic Cultures understood mathematical sets, and the interplay between the moon annual cycle, ecliptic, solstice and seasonal changes on earth.

The First (Lunar) Calendar –

The archaeological record’s earliest data that speaks to human awareness of the stars and ‘heavens’ dates to the Aurignacian Culture of Europe, c.32,000 B.C. Between 1964 and the early 1990s, Alexander Marshack published breakthrough research that documented the mathematical and astronomical knowledge in the Late Upper Paleolithic Cultures of Europe. Marshack deciphered sets of marks carved into animal bones, and occasionally on the walls of caves, as records of the lunar cycle. These marks are sets of crescents or lines. Artisans carefully controlled line thickness so that a correlation with lunar phases would be as easy as possible to perceive. Sets of marks were often laid out in a serpentine pattern that suggests a snake deity or streams and rivers.
