The ballista is actually a further development of known Graeco-Roman and Medieval siege engines. It was designed to hurl stones over a long distance in order to breach enemy walls. Unlike other war machines the ballista was a small weapon that packed a large punch. The energy to launch the stones is created by the extreme tension in the ropes that are tightened by a screw.

Leonardo's ingenious invention has now been launched as a fine wooden model made in accordance with the original drawings and historical models in the Museum of Science and Technology Leonardo da Vinci in Milan.
