One of the key Roman innovations was the development of the vertical, greare waterwheel: the bottom of a large wheel with paddles is dipped into a stream or river and turned by the force of the flow. In antiquity, this water power was primarily applied to turning a grinding stone to mill flour, and the crucial mechanism that allowed this technology was the invention of the right-angle gear (dated to around 270 BC), transforming the direction of motion from a vertical spin of the waterwheel to the horizontal rotation of the grinding stone. Most simply, this can be achieved with a large crown wheel on the waterwheel drive shaft coupled to a cylinder of rods known as a lantern gear or cage gear that is connected to millstone. Altering the relative size of the crown wheel and lantern gear allows you to match the required speed for grinding to the flow rate of different rivers. The water mills were the very first known application of gearing to transfer power, and to represent the earliest roots of mechanization ~Page 168
