Notes The inscription on the base "Sphère d'Après le Système de Copernic adopté par le Conseil Rl. de l'instruction Pque…" refers to recognition of the Copernican system by the General Council of the Revolutionary Government. The system had been banned by the Church for two centuries -the ban was not to be officially lifted until 1830 - and this was thus a demonstration of the triumph of rationality and scientific thinking promoted by the Revolution.
