Artillery range, 1st Century AD

[Sardaukar]

I have not come across any mention of grape-shot in the sources. I know when trying to fire two balls at the same time on a ballista, the chance of them flying all over the place but to the enemy is large... The only siege instrument probably capable of firing multiple stones would have been the onager, but also there, no info.

M.VIB.M.

I thought it would be quite inaccurate..I bet someone tried that in antiquity too. 8) Other idea than using f.ex. wicker basket would be to use rope to tie 2 rocks together bit like this with loose section of rope between rocks:



Alas, I don't have onager to try... That sort of "special shot" would have been time-consuming to make and Romans, being practically-minded people, would probably not bother. Small rocks in wicker basket, maybe.
