ballista

Ancient missile launcher designed to hurl long arrows or heavy balls. The Greek version was basically a huge crossbow fastened to a mount. The Roman ballista was powered by torsion derived from two thick skeins of twisted cords through which were thrust two separate arms joined at their ends by the cord that propelled the missile. The largest could accurately hurl 60-lb (27-kg) weights up to about 500 yards (450 m).
