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
Stevenson, Edward Luther
Geography -- History; Globes
While the representation of the world is not so detailed in certain
respects as we find, for example, on the Valk globes, there nevertheless
is the evidence that the author wished to include such information as in
his judgment should be recorded. There are records of interest in the
newly explored regions of America. California is laid down as a
peninsula. In about latitude 41 degrees there appears a Drake record
reading “Pt. F. Drack.” “Fretum Anian” is represented at latitude 45
degrees. Sixty degrees to the west of this is the somewhat indefinitely
indicated coast line of “Terra Borealis incognita detecta Dom. Ioh. de
Gama,” this being separated from the coast of “Kamtzadalia Terra Jedso”
by “Fretum Vries.” The recently explored regions in the Far East, as in
Australia, New Zealand, Van Diemen’s Land,--each, however, being
represented as imperfectly known,--are made very prominent. There are
scarcely any map records of the period more interesting than are those
to be found on this globe of Doppelmayr’s. The routes of Magellan, 1519;
Nord, 1600; Roggeveen, 1722; Dampier, 1700; Tasman, 1624; Loys, 1708;
Lemaire, 1616, are all laid down. In latitude 60 degrees south and
longitude 300 degrees we find, “Port detecta per Fr. Drack,” and again
in latitude 67 degrees south and longitude 310, “I. deton detecta per F.
Drack.”
To accompany his terrestrial globe, Doppelmayr issued a celestial globe
bearing the same date. A title legend on the latter reads, “Globus
coelestis novus Stellarum fixarum loca secundum celeberrimi astronomi
Dantiscicani Joannis Hevelii Catalogum ad annum 1730 compl. sistens
opera Joh. Gabr. Doppelmaieri M. P. P. exhibitus a Johanne Georgio
Puschnero Chalcographo Noribergensi. A. C. 1728.” “A new celestial globe
giving the location of the fixed stars according to the record of the
celebrated Danish astronomer Johannes Hevelius conforming to the year
1730, by the labor of Johannes Gabriel Doppelmayr, mathematician,
professor, publisher, engraved by Johannes George Puschner, engraver of
Nürnberg, in the year 1728.” In size and in general features of
construction these globes seem to agree, being scientifically and
carefully constructed. A pair of these globes may be found in the
Biblioteca Capitolare of Verona, a pair in the Geographisches Institute
of Göttingen, a copy of the celestial in the Mathematical Salon of
Dresden, a copy of the terrestrial in the Museo di Fisica of Pavia, a
pair dated 1728 in the Germanisches Nationalmuseum of Nürnberg, a pair
dated 1736, 20 cm. in diameter, and three copies each of his globes
issued in 1730, 20 cm. in diameter, and a celestial globe dated 1730 and
20 cm. in diameter, in Dresden. (Fig. 126a.)
