Roman crossbow

[Flavivs Aetivs]

His theory is good, but my issue is that the Romans had crossbows - we know the haute-loire relief and others were crossbows because they display a nut. Furthermore, we have 3 finds of nuts from (almost) the Roman era - the earliest one was posted on here earlier and dates to the 5th century.

Whether or not the Arcuballista was the name for the crossbow, I agree is up for debate.

BTW, what is the word the Strategicon uses? I can't read greak (well... I can read toxoballista in greek but that's it.)
