This beautifully wrought astronomical instrument in copper, surmounted by a bronze imperial eagle, is a reproduction of the summation of man's attempts to measure the movements of the celestial bodies originating with a simple armilla (bracelet), in ancient Greece, of two bands around a sphere representing the Earth, which were the equator and the meridian, to which were added further parallels to cast shadows and indicate the diurnal and annual positions of the Sun and related planets and stars.
