The Trebuchet is an ancient siege weapon used to fire rocks using a swinging arm and man power. This weapon first appeared in China in the 4th century BC. The counterweight trebuchet (our one) appeared in Christian and Muslim lands in the 12th century and made it to the 13th century. This weaponry was used by the Mongol Empire, China, Byzantine Empire and most of Europe.

The medieval trebuchet had a lever and a sling. This fired by applying force to the shorter end of the arm, while the other end held the projectile with the fulcrum in the middle. Heavy lead weights or a pivoting ballast box were attached to the shorter arm. A heavy projectile was placed in a pouch that was attached by two different ropes to the longer arm. When this arm was released the force (mostly weight) created pushed the long arm upward and caused the projectile to be launched into the air.

Making the trebuchets were a lot harder back then compared to now. In the medieval time, all parts of the trebuchet were made by men with equipment. Their main tools were the hammer and mallet, compared to now where we have industrial machinery. Using this poor equipment made it harder to assemble and build the trebuchet, while today it will be four times as quick to build and will be more efficient.

Collecting the materials were a lot harder back than compared to now. The wood for the catapult had to be cut using a saw by men, now we use machinery which is more efficient and easier. All they had back than was nails and metal to construct their catapults. The metal was forged using spare metal parts and broken down objects. These pieces wouldn’t have been cut as nicely and smoothly as the pieces today. Therefore, the pieces took longer to make and weren’t made as perfect compared to the ones today.

Unfortunately we do not have an image of us building our trebuchet. We are using nails, screws, hammers, drills, saws and other equipment which most weren't invented back then.
