The Roman catapult improved on the medieval design by the addition of torsion springs.

• Originally invented by the Greeks over 2000 years ago and widely used by the Romans in battles and sieges, the Catapult had many different methods of firing.
• During the Roman Empire the catapult was refined and improved and this model represents a smaller version of a common catapult style of the time.
• Based on drawings and written records, this Catapult re-creates the way in which tension powered siege engines worked, and can fire the small clay balls (included) and other soft projectiles over 15 feet!
