Roman composite crossbow Arcuballista

Roman composite crossbow Arcuballista Low-poly 3D model

Low-poly historical accurate (as close as possible) reconstruction of a late roman crossbow, called Arcuballista. This kind of crossbow was depicted only two times on reliefs in the West Roman Empire. They seem to have used a rotating nut trigger system, like the kind I modeled here. The bow could have been made from wood or a composition of wood and linen fabric. My textures show the composite version.

The file includes:

  • Arcuballista with shaft, bow, trigger and nut as separate objects


  • Shaft with handle, wedges and pins (500/573)
  • Bow with string (574/586)
  • Nut (106/110)
  • Trigger (46/48)
