Armillary sphere

Armillary sphere dating back to the 20th century, made of a framework arranged in circles showing the equator and the astronomical lines of latitude and longitude. The Earth, Moon, and Sun are at the center of the sphere, which can be used to observe the movements of these astronomical bodies. Orienting the sphere towards a certain star allowed users to read the coordinates on a graduated scale. This sphere is a teaching resource from the Faustino Paluzíe publishing house, founded in 1837, which specialized in astronomical supplies for schools.
