Description
A loxocosm, also known as a tellurion, is a device which shows how the inclination of the earth's axis causes the day's length to vary from season to season. It is an astronomical demonstration device, invented by Sieur Flecheux. It is related to the orrery, which illustrates the relative positions and motions of the planets and moons in the Solar System in a heliocentric model. They were often used to teach astronomy at universities.
