This planetary model was made by the London instrument maker, John Rowley. Called an orrery, or more correctly a tellurium, it is a demonstration device to show the motions of the Earth and Moon around the Sun. Such devices became popular during the 17th century, especially after Sir Isaac Newton (1642-1727) published his universal theory of gravity in 1687. This particular example was made for Charles Boyle, the fourth Earl of Orrery in Ireland.
