The Mangonel was invented by the Roman Empire in the 4th century BC and became very popular later in Europe when it was introduced to the French and then the English in the 12th century AD. It worked alongside ballistae at one point in history and then went into battle with trebuchets at later points in the siege weapon timeline.
The use of the Mangonel spanned for hundreds of years, in which many advances in technology in many areas, military and civilian occurred. Several of these improvements had changed the way armies prepared for battle and how they fought. The tools back then had a huge effect on how well they could produce a quality machine and how quickly they could complete one. Tools from the era included hammers, nails, saws, chisels, and even hand drills (not electric). While these tools seem familiar today, they were nowhere near as accurate or as well made as the tools that we are using in class to create our small siege weapons. This would have made it very difficult to efficiently and accurately create the pieces that were required to build these huge siege weapons. The nails of this time, for example, were large, crude and could often split the wood, while the hand drill used by the Romans would have taken forever to drill a hole through a large thick piece of wood. They did not have glue either, so permanently binding two pieces together was a very difficult task.
The collection of the materials required for the construction of the Mangonel would also have been a very difficult task. Chopping down trees for the wood took a very long time with the primitive saw blades they had and axes while the weaving of the very strong rope required for the tension of the Mangonel would have been very time consuming as well.
I unfortunately did not take photos of building our siege weapon before it was completed.
