We know that like his contemporary, Fortin, he also constructed armillary spheres, one example of which it has been possible to locate. Fiorini thus refers to it, his citation being given in free translation.[178] It is a Copernican sphere, that is, having a representation of the sun placed at the common center of the armillae instead of a representation of the earth as in the Ptolemaic sphere. It may be found in the palace of Sr. Scaramucci in S. Maria a Monte in the province of Florence. Attached to a base of wood about 20 cm. in height is an iron rod 35 cm. long. This rod passes through the several rings, about which they can be revolved, each being in its movement independent of the others. The first circle about the central sun represents the orbit of Mercury, and has written upon it “Éloigné du Soleil 8537, incliné 7 degr., fait sa révolution en 87 jours, 23 heures, 50 m.” The second represents the orbit of Venus, having written upon it the distance 15928-1/2 diameters of the earth, inclination 3 degrees and 22 minutes; it completes its revolution in 2224 days 16 hours and 41 minutes. In a space much larger than that which separates the other circles, there is the orbit of the earth, upon which is written that this planet passes over the ecliptic in 365 days 5 hours and 49 minutes, and that it is 22000 diameters distant from the sun. This ring representing the orbit of the earth is opened for the insertion of a representation of the moon, adjusted to revolve on an adjusted pivot. Armillae have been provided representing the orbits of Mars, of Jupiter, and of Saturn with statements concerning their respective distances from the sun and their respective periods of revolution. The outer and larger armillae represent the colures, the ecliptic, and the horizon, and on the last the inscription, “À Paris chez Delamarche Géog. Rue du Foinʳ Saint Jacques au Collège de M^re Gervais.” In the year 1793 Vincenzo Rosa, a little-known Italian cosmographer, constructed two terrestrial globes, the maps of which being in manuscript. The spheres are of papier-mâché covered with a light coating of plaster. Each of these globes has a diameter of about 100 cm. An inscription in Italian reads, “Vincenzo Rosa fece nel 1793 n. 24. La geografia è quasi tutta delle carte di Robert del Vaugondy e di De-la-Marche.” “Made by Vincent Rosa in the year 1793 n. 24. The geographical information is almost entirely from the maps of Robert de Vaugondy and of Delamarche.” One copy may be found in the Biblioteca Universitario of Pavia, and the other in the Liceo Foscolo of the same city. Fiorini notes that the “n. 24.” of the first is given as “n. 21.” in the second.[179]
