2. Early adopters of the catapult design were Dionysius of Syracuse (who called it katapeltikon) and Onomarchus of Phocis. Katapaltai are mentioned in the Siegecraft (Poliork紩ka) treatise of Aeneas Tacticus, from around 350 BC. It is probable that standard torsion-powered catapults entered in common use in Greek world and Macedon only around 330 BC. Alexander the Great introduced the idea of using them to provide cover on the battlefield in addition to using them during sieges. Projectiles included both arrows and (later) stones. ---
