Counterweight siege machine Manjaniq described by al- Tarsusi



De acuerdo con el Historiador militar Ruben Saez:

"Las piezas de artillería de contrapeso hicieron su aparición en el mundo musulmán en un momento indeterminado durante la primera mitad del siglo VII. Debieron llegar de la mano de los pueblos nómadas, que se movían en el espacio comprendido entre China y el Imperio Persa-Sasánida.

Uno de los modelos que describe al-Tarsusi en su tratado (1187) es el manjaniq turco. Su marco era el más simple de erigir de todos los manjaniqs complejos de tracción manual, pues estaba mucho más abierto que el resto de ejemplares contemporáneos. Sin embargo, el brazo rotatorio, la junta y la unión para las cuerdas eran muy similares.

A pesar de que el bastidor no disponía de unas medidas precisas, sí que era necesario que la viga horizontal se acomodara a unos cánones. Para cualquier manjaniq de tracción humana, las medidas ideales radicaban en que tres cuartos del brazo estuvieran en el lado de la honda y tan sólo una parte, en el extremo de las cuerdas desde donde se disparaba la máquina."

A trebuchet ( /ˈtrɛbəʃɛt/ treb-ə-shet or /ˌtrɛbjʊˈʃɛt/ treb-ew-shet; French: trébuchet) is a siege engine that was employed in the Middle Ages. It is sometimes called a counterweight trebuchet" or "counterpoise trebuchet" in order to distinguish it from an earlier weapon that has come to be called the "traction trebuchet", the original version with pulling men instead of a counterweight. Man-powered trebuchets appeared in the Greek world and China in about the 4th century BC.




The counterweight trebuchet appeared in both Christian and Muslim lands around the Mediterranean in the twelfth century. It could fling projectiles of up to three hundred and fifty pounds (140 kg) at high speeds into enemy fortifications. Occasionally, disease-infected corpses were flung into cities in an attempt to infect and terrorize the people under siege, a medieval form of biological warfare.[citation needed]

The trebuchet did not become obsolete until the 15th century, well after the introduction of gunpowder, which appeared in Europe in second half of 13th century. Trebuchets were far more accurate than other medieval catapults.

The term "mangonel" is very inexact. It can mean different things depending on the time and area of the world. (In Arabic "al-manjaniq" means trebuchet, for instance. Or French "mangonneau", meaning a trebuchet-like device powered by people pulling on ropes rather than a falling counterweight.) It comes from the Greek word manganon, meaning siege engine.
