a hurling engine with a long arm that pivots between two posts. At one end of the arm is a weight, at the other is a sling or simply a projectile. The trebuchet could hurl a 20-kilogram stone a distance of 100–150 meters. Dating from antiquity, the weapon was used until the 15th century in the siege of fortresses.
