Siege Machines Introduction: Siege machines might have been ancient inventions built to bring an enemy to the breaking point, but the modern world has found a great deal of delight in them as well. Trebuchets, catapults, and ballistae were once used to destroy castle walls, to break through a line of troops, or to throw objects inside castle walls or on enemy ships. Now, these devices are loved for their ingenious use of science and math – and sometimes just for the sake of entertainment. From the Middle Ages to Middle Earth, catapults, trebuchets, battering rams, ballistae, and more have held our attention captive. Indeed, the entertainment industry has tapped into this fascination for some time: the British comedy Monty Python and the Holy Grail, the epic Lord of the Rings films, and kid comedy Night at the Museum have all featured these flinging devices. Many of the big guns of siege warfare are so popular that they are built all around the world either as models, life-sized constructions, or some variation between the two. From small models built in classrooms in Trenton, New Jersey, to towering reconstructions in French chateaux museums, these historic weapons are capturing the imaginations of young and old alike. Math, physics, engineering, problem solving, and history are all topics that can be enhanced by building and using siege machines. Even building small versions can open up huge doorways to learning.
