Ballista | 4th century BC - 5th century AD | Torsion-powered bolt/stone thrower | Roman legions, Siege of Syracuse | Giant crossbow firing bolts or stones, highly accurate at 500m range, Romans deployed them in batteries, anti-personnel weapon |
Onager (Mangonel) | Roman era - medieval | Torsion-powered single-arm catapult | Roman frontier defense, Crusades | Named after wild donkey (kicks hard), simpler than trebuchet, could hurl stones and incendiaries, widespread use |

Scorpio (Scorpion) | Roman Republic/Empire | Small torsion crossbow on tripod | Julius Caesar's Gallic Wars, Masada | Portable anti-personnel weapon, each legion had 60, accurate bolt shooter, smaller cousin of the ballista |
Trebuchet (Traction) | 5th century China - 12th century | Human-pulled ropes swing throwing arm | Chinese and Byzantine sieges, early Crusades | Predecessor of counterweight trebuchet, team of 40-250 men pulling ropes, faster rate of fire, less powerful |
