History of energy-conversion technology britannica

A horizontal-shaft water mill was first described by the Roman architect and engineer Vitruvius about 27 bce. It consisted of an undershot waterwheel in which water enters below the centre of the wheel and is guided by a millrace and chute. The waterwheel was coupled with a right-angle gear drive to a vertical-shaft grinding wheel.
