Mangonel

Approx. Period: 200 AD
Length: 5.0m Width: 3.0m

Siege weapons and military machines developed slowly based on designs such as the mangonel or onager. These crude devices used the energy of twisted sinews and ropes to launch rocks and burning projectiles over defended walls. The construction of the mangonel had to withstand severe impacts and would have been extremely difficult to control.

The launching arm of the mangonel is wound back against the torsion of the rope by lever and pulleys. Once restrained, the tray at the end of the beam is loaded with a suitable rock. The catch restraining the launching arm is released and the arm pivots forward to release the missile. Though probably regarded with awe in their own time these weapons would have had limited range and usefulness.
