Performance of Greek-Roman Artillery

The main throwing machines invented and used by the Greeks and adopted, more widely, by Roman armies are examined. The kinematics and dynamics of both light and heavy Greek-Roman artillery are used in order to accurately assess its performance. Thus, a better understanding is obtained of the tactics and strategies of the legions of the Roman Empire as well as the reasons for some brilliant campaigns. Reconstructions of a repeating catapult, considered to be the ancestor of the modern machine gun, are also presented. The development of the mechanical design of such machines is discussed and pictorial reconstructions proposed.
