Armillary spheres have become an icon of science with their elegant rings and beautiful silhouettes.  Armillary spheres may 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 beautiful 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 5 inches (12.7 cm) tall, 3 1/2 inches (8.9 cm) in diameter, and weighs 12.3 ounces (350 g).
The Medium Sized Brass Demonstrational Armillary Sphere measures 8 1/8 inches (20.6 cm) tall, 5 3/8 inches (13.7 cm) in diameter, and weighs 1.8 pounds (0.8 kg).
The Regular Sized Brass Demonstrational Armillary Sphere measures 11 inches (28 cm) tall, 7 1/2 inches (19 cm) in diameter, and weighs 3.6 pounds (1.6 kg).
The Large Brass Demonstrational Armillary Sphere measures 20 1/2 inches (52 cm) tall, 14 inches (35.6 cm) in diameter, and weighs 12.2 pounds (5.5 kg).
The Extra Large Brass Demonstrational Armillary Sphere measures 35 inches (88.9 cm) tall, 25 inches (63.5 cm) in diameter, and weighs 34 pounds (15.4 kg).
Please check these dimensions before ordering, as the largest models are very large, suitable for store and restaurant displays and often too large for a desk or shelf.
We also offer several Armillary Sphere Sundials, a Celestial Armillary Globe and a Universal Equinoctial Sundial.
The Small Brass Demonstrational Armillary Sphere is available for only $45, the Medium is only $65, the Regular Sized Sphere is $89, the Large is $219.50, and the Extra Large Brass Demonstrational Armillary Sphere is available for $849.
