<strong>Terrestrial</strong> <strong>and</strong> Celestial Globes.<br />

the New York Public Library, a set of the terrestrial <strong>and</strong><br />

the <strong>celestial</strong> gores is in the British Museum, <strong>and</strong> of<br />

the terrestrial in the Germanisches Nationalmuseum of<br />

Niimberg.<br />

Of the second edition, copies of the unmounted gores maybe<br />

found in the Bibliotheque Nationale, in the British<br />

Museum, in the private library of Prince Trivulzio of<br />

Milan. A mounted pair of the second edition may be found<br />

in the Osservatorio Astronomico of Rome (Fig. 65), <strong>and</strong><br />

in addition a second example of the <strong>celestial</strong> globe, which<br />

is described as having excellent mountings of brass, so<br />

arranged as to make possible a revolution of the globe both<br />

on an equatorial axis <strong>and</strong> an axis of the ecliptic. Its horizon<br />

circle is supported by two brass semicircles, the whole resting<br />

on four wooden columns of modern construction, <strong>and</strong><br />

these in turn resting on representations of lion's paws in<br />

bronze. An example of the mounted terrestrial globe is said<br />

to belong to the collection of Sr. Bazolle of Belluno, which<br />

example once belonged to the Counts of Pilloni.<br />

Attention has been called to the peculiar gore map of<br />

Santa Cruz," <strong>and</strong> to the fact that his method of construction<br />

seems not to have won favor. We, however, find among the<br />

map makers of Italy, in the period of which we are now<br />

speaking, one Antonius Florianus,^ who, if not copying the<br />

plan of Santa Cruz, followed closely his scheme. His map,<br />

of which numerous copies are known (Fig. 66), seems to<br />

have been prepared for mounting on a ball, although no<br />

such mounted example can now be located. With the poles<br />

as centers, <strong>and</strong> with a radius equal to one quarter of the<br />

circumference of the sphere he proposed to construct, he<br />

drew his equatorial circles, which thus gave him two hemispheres,<br />

respectively, a northern <strong>and</strong> a southern; in the same<br />

manner he drew his parallels at intervals<br />

using<br />

of ten degrees,<br />

for each the <strong>com</strong>mon polar centers. In each of the<br />

hemispheres he drew thirty-six sectors, each sector being<br />

made to represent ten degrees of longitude, <strong>and</strong> they were<br />
