The celestial globe bears the title, “Globe céleste calculé pour l’an 1700. Sur les observations les plus récents. Par. G. De l’Isle Géographe,” and is dedicated “À Son Altesse Royale Monseigneur le Duc de Chartres. Par son très humble et très obéissant Serviteur De l’Isle,” with the following reference to the privilege “À Paris Chez l’Auteur sur le Quai de l’Horologe à la Couronne de Diamans. Avec Privilége du Roy pour 20 ans. 1700.” While it has not been possible to obtain a detailed description of Delisle’s globe maps, they are referred to as giving practically the same information as his plane maps, many of the latter to be found in our important library collections, and cannot be considered rare.[124] The several constellations which he has represented on his celestial globes are those of Ptolemy to which have been added two in the northern hemisphere and thirteen in the southern, and the year chosen for the representation of the position of the stars is 1700. In general the names chosen for the several constellations are French, though a few are in Latin. [Illustration: Fig. 118. Terrestrial Globe of Guillaume Delisle, 1700.] A pair of Delisle’s globes may be found in the Königliches Museum of Cassel, dated 1709; a pair dated 1700 in the Museo di Strumenti Antichi of Florence, and a terrestrial globe dated 1700 in the Real Biblioteca of Madrid (Fig. 118). Weigel, Castlemaine, Coronelli, and Treffler, as has been noted, represented a tendency in globe construction in their day which we have referred to as the ultrapractical. It was impossible that their ideas should find anything like a general acceptance and approval. A globe eleven or fifteen feet in diameter, in the better judgment of astronomers and geographers, could not be counted as possessing superior scientific value, and globes of such dimensions seem only to have won the praise of the novelty-loving contemporaries, and the same general criticism may be passed upon the smaller globes of Castlemaine and Treffler. Perhaps, however, one may well add that in all this a desire was expressing itself for improvement in globe construction.
