- Peter van Rossum, Alexander the Great expert.
The Ballista was a siege engine invented by the Ancient Greeks, a supersized killing machine. It was the Special Weapon of Alexander the Great.
The Ballista resembled an enlarged Gastraphetes set at an angle to the base. It had two torsion springs (ropes made from animal sinew) attached to the bow arms, which in turn were attached to the bowstring.
- Range: 500 yards
- Ammo: 4" bolts
- Mag: Single shot
The Ballista was drawn with hand winches, twisting the already taut torsion springs to create far greater power could otherwise be achieved. This resulted in faster and further-launched projectiles.
Following the development of the torsion spring, the first ballista was allegedly built by Dionysius of Syracuse around 400 BC. It was not until Philip II of Macedon and later his son Alexander the Great that the Ballista gained widespread recognition. It was later adopted by the Romans, who further adapted the weapon (which eventually resulted in the creation of the Scorpion). The weapon was so ahead of its time, it survived well into the Middle Ages before more advanced siege engines finally rendered it obsolete.
