BRASS ARMILLARY SPHERES ON WOODEN BASE IN ANTIQUE FINISH
ITEM
CODE MIS-4478
Armillary spheres have
become an icon of science with their elegant rings and beautiful
silhouettes. Thought to have been invented by Eratosthenes around 255 BC,
these instruments consist of a set of graduated rings representing circles on
the celestial sphere, such as the meridian, equator, ecliptic horizon, tropics,
and colures. With an armillary sphere, one could track the path of the
sun for any given day of the year or determine a star's coordinates. The
brass sphere at the center of the armillary represents the Earth.
These reproductions of
European Demonstrational Armillary Spheres show relationships among important
lines and points in the sky such as The Celestial Equator, the Celestial Poles,
the Ecliptic and the Vernal Equinox. The ecliptic rings are divided with
the signs of the zodiac and these Armillary Spheres have an extra divided axis
where the entire celestial sphere can be set to any angle. The rims of
the armillary spheres are marked "A PARIS Chez G. Gobille a P Ache
Royalle." These armillary spheres are solid brass with a rich
antique patina finish that will not tarnish or show fingerprints. The
heavy solid brass bases are mounted on turned solid hardwood, and the bottoms
are covered with felt.
The Small Brass
Demonstrational Armillary Sphere measures 11 inches (27.8 cm) tall, 6.5 inches
(16.5 cm) in diameter.
SATISFACTION GUARANTEED, FANTASTIC FOR ANY COLLECTION
