Orrery

  • An Orrery is a mechanical model driven by clockwork of either the Solar System or the Earth, Sun and Moon. The first Orrery was made in 1704 and given to Charles Boyle, 4th Earl of Orrery (hence the name).
  • Cicero (106-43 BCE) wrote that Posidonius (135-51 BCE) constructed an Orrery (similar to the Antikythera Mechanism), which showed the positions of the SunMoon and the five planets.
