The Heliocentrism of the Ancient: between Geometry and Physics.

Geocentrism remained a fundamental characteristic of ancient astronomy, though there were moments in the history of this discipline when they argued for the orbital movement of the Earth around the Sun and even its rotation around its own axis. Practically, at the crossroads between physics and geometry, astronomy rejected a correct thesis in geometric terms, based on seemingly arguable physical theories. In this paper, my goal is to present from a synthetic and diachronic perspective several elements of the cosmologic model developed by the Greeks until the time of Aristarchus of Samos, thus highlighting several aspects of physics that made it impossible to accept heliocentrism, explainable in mathematical terms, which he promoted.
