In this way the blows of ballistae and the force of fires will be repelled by them.
But Belisarius placed upon the towers engines which they call "ballistae."
I have now given those symmetrical proportions of ballistae and catapults which I thought most useful.
They are usually classed as (a) catapults and (b) ballistae (λιθοβόλοι).
Their ballistae threw stones, weighing a hundred weight, a distance of a quarter of a mile.
It is said that from the ballistae stones weighing one hundred pounds could be sent half a mile.
Ballistae are constructed on varying principles to produce an identical result.
