Mechanical Drum

This wheeled drum was fitted to a cart. The drum is capable of playing various patterns of sounds, which are regularly repeated. The axle of the cart wheel operates a toothed wheel, thus actuating five beaters on either side of the drum. During Leonardo’s time, the drum had uses in stage productions to help dramatise particular scenes and acts. It also had a military use for marching, ceremonial events and, of course, during the heat of battle to provide basic commands and communication.
