Orrery An astronomical toy to show the relative movements of the planets, etc., invented by George
Graham, who sent his model to Rowley, an instrument maker, to make one for Prince Eugéne. Rowley
made a copy of it for Charles Boyle, third Earl of Orrery, and Sir Richard Steele named it an orrery out of
compliment to the earl. One of the best is Fulton's, in Kelvin Grove Museum, West End Park, Glasgow.
