To my understanding the terms cheiroballistra and scorpion describe completely different weapons. First is wide-spaced, iron-framed, and according to some (myself included) it was an in-swinger. Scorpion was either a wooden-framed, narrow-spaced outswinger, or a one-armed stone thrower. There are those who think that all ballistas were in-swingers and that the two existed side by side until around 100 AD when the iron-framers made the euthyone redundant.
