On the possible discovery of precessional effects in ancient astronomy

TL;DR

This paper reviews evidence suggesting ancient cultures may have observed precessional effects like star position shifts, highlighting intriguing hints but lacking definitive proof, and encouraging further research into ancient astronomy.

Contribution

It compiles and analyzes historical hints of precessional effects observed by ancient civilizations, emphasizing the potential for early astronomical discoveries.

Findings

Ancient Egypt shows notable hints of precessional observations

No definitive evidence yet confirms ancient discovery of precession

The review stimulates further research into ancient astronomical knowledge

Abstract

The possible discovery of astronomical effects due to precession - such as the shift in the declination of heliacal raising of bright stars or the precession of the equinoxes - is reviewed for various ancient cultures in the world. Although definitive evidence of the discovery is still lacking, the quantity of hints (for instance, coming from ancient Egypt) is impressive and stimulating in view of further research.
