Armillary sphere

An armillary sphere or spherical astrolabe dating back to the early 20th century. Constructed from a framework of circular wooden pieces covered in printed paper, from which it gets its name. A geocentric armillary sphere or spherical astrolabe shows the earth surrounded by armillas (from the Latin word armilla meaning circle) depicting the main circles of the celestial sphere. Among other features, the celestial equator, ecliptic plane, horizon, and the zodiac can be observed, along with their corresponding scales which were used to identify the celestial coordinates of the stars. This spherical astrolabe is a reproduction of one listed in the inventory of teaching resources for schools by the Faustino Paluzíe publishing house (founded 1837).
