Desktop Scorpio Kickstarter

[Nathan Ross]

Somewhere during the middle ages the terms reversed.

Ammianus Marcellinus also calls a bolt-shooter a ballista. Extra confusingly, he says the single-arm stone throwing onager was previously called a scorpion! So the term reversal (unless Ammianus was using obscure terms on purpose, or was just confused himself...) seems to have happened at some point before that.
