Word of the Day -- Scorpio

The scorpio or scorpion was a type of Roman artillery piece. Also known by the name of the triggerfish, it was described in detail by Vitruvius. In the progressive evolution of catapults, the next major improvement after the scorpio was the cheiroballistra. A weapon of remarkable precision and power, the scorpio was particularly dreaded by the enemies of the Roman Empire.

The scorpio was a smaller catapult-type weapon, more of a sniper weapon than a siege engine, operated by one man. The scorpio was basically an early crossbow, a "catapult with bolts", probably first invented by the Greeks, then later adopted and used on a larger scale by the Roman legions. This catapult used a system of torsion springs to propel the bolts.
