Segmental gears ("a piece for receiving or communicating reciprocating motion from or to a cogwheel, consisting of a sector of a circular gear, or ring, having cogs on the periphery, or face." and epicyclic gears were both first invented by the 11th century Arab engineer Ibn Khalaf al-Muradi from Islamic Spain. He employed both these types of gears in the gear trains of his mechanical clocks. Simple gears have been known before him, but this was the the first known case of complex gears used to transmit high torque.
