To accompany his terrestrial globe, Doppelmayr issued a celestial globe bearing the same date. A title legend on the latter reads, “Globus coelestis novus Stellarum fixarum loca secundum celeberrimi astronomi Dantiscicani Joannis Hevelii Catalogum ad annum 1730 compl. sistens opera Joh. Gabr. Doppelmaieri M. P. P. exhibitus a Johanne Georgio Puschnero Chalcographo Noribergensi. A. C. 1728.” “A new celestial globe giving the location of the fixed stars according to the record of the celebrated Danish astronomer Johannes Hevelius conforming to the year 1730, by the labor of Johannes Gabriel Doppelmayr, mathematician, professor, publisher, engraved by Johannes George Puschner, engraver of Nürnberg, in the year 1728.” In size and in general features of construction these globes seem to agree, being scientifically and carefully constructed. A pair of these globes may be found in the Biblioteca Capitolare of Verona, a pair in the Geographisches Institute of Göttingen, a copy of the celestial in the Mathematical Salon of Dresden, a copy of the terrestrial in the Museo di Fisica of Pavia, a pair dated 1728 in the Germanisches Nationalmuseum of Nürnberg, a pair dated 1736, 20 cm. in diameter, and three copies each of his globes issued in 1730, 20 cm. in diameter, and a celestial globe dated 1730 and 20 cm. in diameter, in Dresden.

Fiorini notes the existence of a large terrestrial globe belonging to the Marquis Luigi Cusani,[153] which probably was constructed in the early eighteenth century, perhaps before 1730, by order of Cardinal Agostino Cusani. The globe, unsigned and undated, is of papier-mâché, having a diameter of about 120 cm. The paper gores with which the sphere is covered are not all of like form, but all are cut at the line of the equator and at latitude 80 both north and south, the usual circular disc being provided for covering the polar areas. On its surface the map has been drawn by hand, and practically all of the geographical names recorded are in the Italian language. The globe is mounted on a solid base, having a heavy horizon circle of wood, which is graduated, and on its surface are the names and the signs of the several zodiacal constellations, the names of the months and of the principal winds or directions. The meridian circle, within which the sphere revolves, is of brass and is graduated. It is reported to be in a good state of preservation.
The Biblioteca Comunale of Siena possesses two anonymous terrestrial globes, according to report of Fiorini, the one having a map in manuscript, the other having an engraved map.[154] The first of these, unsigned and undated, probably of the second quarter of the century, has a diameter of about 120 cm. The sphere is of wood, the surface of which is covered with mastic or varnish, and on this the map has been drawn. It is constructed to revolve within its simple mounting of wood by means of a crank. The title legend reads “Globe terrestre Dressé selon les observations de l’Acad. Royale de Paris et des autres Acad. plus célébrés d’Europe.” “Terrestrial globe constructed according to the observations of the Royal Academy of Paris and of other Academies the most celebrated in Europe.” In addition to the above legend one finds the following inscription: “On a pris la longitude des villes principales des Tables de Mur Philippe de La Hire. Les autres villes ou il n’ a point d’observations sont icy places en la même distance des villes principales dans la quelle on les voit dans les cartes de M. Guillaume de l’Isle.” “The longitudes of the principal towns have been taken from the tables of Mur Philippe de La Hire.[155] The other towns which have not been located from observation are placed at the same distance from the principal towns as they are located on the maps of M. Guillaume de l’Isle.”
It seems probable that this globe was constructed in France, and from the particular references to La Hire and Delisle one may infer, as noted above, that it belongs to the early eighteenth century. Parallels and meridians are drawn on the surface of the globe at intervals of ten degrees, and one conspicuous wind rose with sixteen radiating lines is placed in latitude 30 degrees north and longitude 350 degrees counting from the prime meridian, which passes through the Island of Ferro. This globe, it is thought, came to the Siena Library about the year 1810, at the time of French rule in Tuscany, together with the library of the Convent of S. Augustine, but how it came to have place in the Augustine convent is unknown.
The second Sienese terrestrial globe, like the one just described, probably belongs to about the same date.[156] It has the following legend conspicuously placed: “Globo terracqueo corretto et accresciuto secondo le nuove scoperte. Anno 1744. In Roma nella Calcografia del R:C:A: al Piè di Marmo.” “Terrestrial globe corrected and enlarged according to recent discoveries. 1744. In Rome in the engraving establishment of R. C. A. at the foot of the marble.” The globe ball is of wood, having a diameter of about 50 cm. Additional information concerning this globe it has not been possible to obtain. Copies of it may be found in the Biblioteca Comunale of Imola, in that of Osimo, in that of Savignano, and in the Seminario Vescovile of Ivrea.
