Terrestrial and Celestial Globes Volume 2: Their History and Construction Including a Consideration of their Value as Aids in the Study of Geography and Astronomy

the west, which are the Fortunate Islands in the Atlantic Ocean, but now
called the Canary Islands. In these he fixed the first meridian, and
this hypothetical beginning almost all who have followed him have been
led by his authority to retain. Not a few in the century just passed
have thought that the beginning should be made where the magnetic needle
points directly to the north. But these, as they disagree among
themselves are mistaken. We follow in the footsteps of Ptolemy and have
chosen the same island, and placed the meridian line in the Island of
Ferro, one of the principal islands of the Fortunate group now called
the Canaries.”
In addition to the one just quoted there are a few other legends
relating to geographical discoveries which contain allusions, very
similar to the many which may be found on certain other globes of the
period, adding little or nothing that is new.
The celestial globe, mounted practically the same as the terrestrial,
contains the following legend: “Ecce damus methodo Ptolemaica seu
Orteliana coelestium siderum quotquot hodie extare comperimus schemata,
situs et ut decet reperiuntur perfecta. Sunt enim ex descriptionibus
Hipparchi, Ptolomei, Alphonsi, Copernici, per Tyconem Brahe ad trutinam
examinata, nec non Joannis Bayeri, qui Uranometriam per imagines in
tabulis aeneis expressit. Et nunc per me D. Silvestrum Amantium
Moroncelli Fabrianen̄ Abbatem Bened. Congreg. Silv. calamo descripta
coloribusque effigiata adattataque ad Ann. 1716.” “Observe that we give
after the method of Ptolemy or Ortelius the settings of the stars of
heaven, as far as they have, to the present, been discovered, and as far
as their positions have been made known. We have employed the
descriptions of Hipparchus, Ptolemy, Alfonso, and Copernicus, as tested
and confirmed by Tycho Brahe, and also by the observations of Johannes
Bayer, who expressed the star system (of Tycho Brahe) objectively in
brass tables, now by myself D. Silvester Amantius Moroncelli of
Fabriano, Benedictine Abbot of the Silvestrin Congregation. All these
have been expressed in letters and represented in colors, and
accommodated to the year 1716.”
