The Orrery’s base serves multiple purposes. In addition to being the support system for the Orrery, it contains a gear box underneath it to transmit the rotation of the hand crank up through the main shaft. It also provides a surface to engrave the year markers which, together with the calendar gear, indicate the date represented by the current position of the planets.
