Like the matching terrestrial globe inv. 2699, this celestial globe, made by Guillaume Delisle, is dedicated to the Duc de Chartres Louis-Philippe-Joseph d'Orléans. The northern and southern constellations comprise some additions to the Ptolemaic group, while those of the zodiac are the conventional ones. Provenance (identical to that of item inv. 2699): Medici collections; donated by Grand Duke Peter Leopold to the Museo di Fisica e Storia Naturale of Florence at its foundation in 1775.
