Description


This is a fine 1754 diagram of an Armillary Sphere by Gabriel Ramirez. The diagram illustrates an Armillary Sphere along with two smaller figures in the lower left and right quadrants respectively. The Armillary Sphere is an old astronomical observation device used to differentiate between the Ptolemaic system and the Copernican system, by displaying the relationship between the various objects in the sky. The diagram depicts the central terrestrial globe with rings representing the main celestial circles.

This chart was originally prepared in French by Abbot M. Pluche and translated into Castilian Spanish. Engraved by Jose Andrade for publication in Volume VII, Part 4 of D. Gabriel Ramirez's Espectaculo de la Naturaleza, O Conversaciones a Cerca de Las Particularidades de la Historia Natural.
