The myth of the mangonel: torsion artillery in the Middle Ages

Abstract

Medieval siege artillery has been a subject of fascination since the antiquarians of the 19th century re-discovered the Middle Ages and then re-created it as an image of their own imagination, in the process generating many false ideas. Most of these myths have been corrected. But one that remains to this day is that the torsion-powered late Roman onager lived on for another millennium in the form of the mangonel.
