Terrestrial and Celestial Globes Volume 1: Their History and Construction Including a Consideration of their Value as Aids in the Study of Geography and Astronomy
Stevenson, Edward Luther
Geography -- History; Globes
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]
