Description:

Signed on the outer label "The Celestial Indicator by Henry Bryant, Hartford, Conn. Explanations and Directions.....Patented Sept. 10, 1872 the Celestial Indicator is a unique American combination of an Armillary Sphere (rings showing the celestial circles of the earth and sky) and an Orrery (showing relative planetary movements in the solar system). The celestial indicator is comprised of a series of calibrated brass armillary bands which form a frame enclosing the orrery mechanism of the planets represented by wooden spheres on wire supports, a painted paper covered earth with revolving moon, a rectangular brass plate engraved "Asteroids" and at the centre a brass sphere representing the Sun, all turned by a knob on the outer part of the assembly. The broad brass band with the instruction label outside has a printed paper strip all around the inside showing the stars in the Zodiac belt plus other astronomical information and the central near circular plate has a label showing the northern sky plus the Serpent constallation. All mounted on a round black cast iron base with gilt decoration with an adjustment to set the angle of the full assembly at precise inclinations. High definition images available on request. Equitorial diameter of the sphere 12" (30 cm) height 18" (46 cm). See similar examples in The Smithsonian Institute, The National Museum of American History and The Connecticut Historical Society. I believe this to be one of the most interesting and sophisticated American planetary devices ever invented. Packing free, transport at cost.
