The globe of Pope Julius II, in question, must then have been constructed prior to 1505, seeing this to be the year of the correspondence to which reference has been made above. From the partial description given in the letters we are led to the conclusion that they were not engraved metal globes, but their maps were manuscript, and were well decorated by hand. The Vatican Museum is still in possession of a celestial globe which may well be one of those once belonging to Pope Julius II, the terrestrial globe having disappeared. From the interesting description of Denza131 we learn that this remaining one is a hollow wooden ball, 95 cm. in diameter. That there might be an even surface on which to draw the star map, a covering of plaster had been provided, 4 mm. in thickness. It is furnished with a somewhat elaborate base, ornamented with sphinxes with the heads of eagles and the feet of lions. Its horizon circle, supported by four quarter circles, is a band 5 cm. wide, the surface of which is divided into five concentric circles, within which are the names of the several signs of the zodiac in Latin, the names of the days of the month, and the names of the eight principal winds in the Italian language. Along the outer edge of this horizon circle is the following inscription, “Daniel Chassignet. Fecit. Romae 1617,” a name and date clearly applying only to this circle or to the globe’s mounting. It has a meridian circle within which the sphere revolves. On the surface of the ball we find represented the principal circles, that is, the equator, the tropics, the polar circles, with five meridians, and the ecliptic, its twelve signs being represented in gilded characters. The coat of arms, painted near the south pole, is not that of Pope Julius II, but of Cardinal Gian Stefano Ferrero, Bishop of Bologna, who became a supporter of Juliani della Rovere in his candidacy for the papal office, and to which office he was elected, becoming known as Julius II. Fiorini thinks it probable that the globe was presented by Cardinal Ferrero to the Pope, and that while in his possession the coat of arms was painted on its surface. It is indeed not improbable that it was originally constructed for the Cardinal. Contrary to the opinion of Denza, Fiorini’s conclusion is that the decoration of the globe is not to be attributed to Giulio Romano, a distinguished pupil of Raphael, and the arguments presented seem acceptable.132
As proof of an existing interest in globes, in Italy, in the first years of the sixteenth century, other than that given by the letters of Isabel of Este, and the globes of Pope Julius, we find an allusion to the subject by Friar Marco da Benevento, member of the order of Celestini and a renowned mathematician. In his ‘Orbis nova descriptio,’133 which he added to an edition of Ptolemy, issued in Rome in the year 1507 or 1508, he alludes to the difficulty of representing the earth upon a solid sphere, adding that the greater the size of the same the greater the difficulty there is in moving it, and that the larger the globe the more difficult it is to take in at a glance any considerable part of the map. While making no specific mention of any of the globe makers of the time, his reference to the subject seems to assure us that globes were objects more or less familiar to students of geography in his day.
Fiorini cites at some length an inventory relating to the printing establishment of Alexander Rosselli of Florence, under whose father, Francesco, this establishment became famous.134 The father died in the year 1510, but it is probable that this artist, painter, and miniaturist, who issued for his establishment numerous maps, printed, likewise, globe gores. While the inventory gives us intimation of his great activity, we have no further knowledge of his work as a globe maker than is contained therein. It may well have been that the construction of globes with printed gore maps had its origin in Florence in the very early sixteenth century, and that a credit we have been accustomed to give to German map makers135 is in reality due the Rosselli family of Italy, particularly Francesco Rosselli.
Fiorini likewise alludes to a letter written by Friar Zenobio Acciaioli, dated Lucca, May 12, 1509, and addressed to the Florentine, Luigi Pietro Guicciardini, brother of the distinguished historian.136 Request is made in this letter that assistance and advice be given to a brother monk, Barnaba Canti, who had been asked to describe a map on which the newly discovered lands were well drawn, there being written on the map the history of the islands, with a description of the lands and of the customs of the peoples. Attention is likewise called to a globe which Canti possessed, it being designated as “sphaerula” or small. The letter further notes, “Cupit autem illam Joannes teutonicus astrologus, ut ex suis ad me literis quas inclusas tibi in his mitto, videre poteris.” “John the German astronomer desires this (map?) as you will be able to see from his letters to me which enclosed I send to you.”
It is ingeniously argued that the Joannes referred to was none other than John Schöner, who later became famous as mathematician and as map and globe maker, and that the globe referred to by Acciaioli was one in the construction of which the globe gores of Rosselli had been used, since “Joannes teutonicus” in all probability would not have thought of receiving from Italy a manuscript globe.
For the history of globe making as practiced in Florence in these early years, there is in the record of the deliberations of the Florentine Signoria, dated December 30, 1515, an entry of interest.137 The Priors and Gonfaloniers directed attention to the sphere, which had been placed in the orologia or clock room, noting that the terrestrial orb which had been painted thereon was greatly damaged, “… super qua depicta est figura et situs orbis terrarum … devastata et male picta.” They expressed a desire that it should be fully repaired and be made suitable as an adornment of the wonderful clock, and in keeping with the remarkable celestial sphere which was placed near by: “ut similis sit et non discrepet, in sua qualitate, a mirabili orologio predicto, et a convicina et mirabili palla, ubi apparet figura et ambitus celi.” Having knowledge of the ability and skill of Friar Giuliano Vannelli, it was decided to entrust the reconstruction to him. We learn that on June 28, 1516, the Signoria directed payment of fifty large florins be made to Friar Giuliano, in addition to the six already paid, for the painted sphere; that on July 17, 1516, the officers of the Monte Comune directed the payment of fifty-six large gold florins to “Don Giuliani Vanegli” “in appreciation of his work, and as a reward for having made one of the two balls of the clock, which is in the large room of the Signoria, which ball he both designed and painted, showing on it the entire universe, according to Ptolemy and other authors who deal with the subject.” Fiorini notes that as at this time the terrestrial sphere was damaged it probably was several years old, and that if badly painted (male picta) the inference is, it failed to record the latest discoveries. If the exact date of the construction of the spheres which adorn this clock cannot be ascertained, it was at least before 1500.138
We have further evidence of Vannelli’s interest in globe construction contained in a letter dated Rome, November, 1524, and addressed to Cardinal Giovanni Salviati, a legate of Lombardy. “Your Excellency has asked me to make for you a small ball de situ orbis, of the size and character of that of Giovanni Ruccellai. … I have made the said ball, and have varnished it, but the weather being bad it will not be dry for eight or ten days. … Your Excellency also tells me that you would like to have a large globe similar to that of Mons. R. Rodulphis, which I have begun. If you desire that I should go on with the work, I shall willingly do so, putting aside all other work to serve you.”139
To the interest in globe making north of the Alps in the first quarter of the sixteenth century attention may next be directed. In a letter written by Johannes Trithemius to Vuilhelmus Veldicus Monapius, dated August 12, 1507, may be found an early allusion to globes. He says: “Orbem terrae marisqui et insularum quem pulchre depictum in Vuormotia scribis esse venalem, me quidem consequi posse obtarum, sed quadraginta pro illo expendere florenos, nemo mihi facile persuadet. Comparavi autem mihi, ante paucos
