A tellurian, having a colored four-inch tin terrestrial globe manufactured by the J. Chein Company within a semi-spherical open blue plastic hood, turning at the end of a metal arm and revolving around a central yellow plastic sphere representing the sun. The entire assembly is mounted on an ebonized wooden stand with a circular tapering support, set on a round base with a zodiac calendar printed in white. The arm has a handle for turning and a zodiac pointer to one side of the tapering support. Leopoldville in the Belgian Congo is shown, indicating a date before 1966.
The Universal Planetarium is a demonstration model of the movement of the earth relative to the sun showing various astronomical principles including solar eclipses and the succession of seasons. The chain drive, engaged by turning the arm, is very simple, causing the earth to shift directions to show the seasons, but not causing the earth to spin. Instead the earth is rotated by hand. Along with its educational objectives, the tellurian is also decorative and entertaining.
