Description
An armillary sphere was an ancient mathematical instrument possibly dating back to the 2nd century. They were used to demonstrate the movement of the celestial sphere around the stationary earth. It is divided into 360 degrees for showing the sun's ascension in degrees; and also, into 24 hours, for showing its right ascension in time. Original photo by Nadalyn Larsen.
