Criticism.-This engine was moved into position on rollers and then props were placed under its sides to adjust the range of the projectile.
The end of the arm was secured by the notch of the large iron catch and was released by striking down the handle of the catch with a heavy mallet.
The arm is, however, too long for the height of the crossbar against which it strikes and would probably break off at its centre.
The hollow for the stone is much too large, as a stone big enough to fit it could not be cast by a weapon of the dimensions shown in the picture.

2 In medieval times catapults which had not slings cast great stones, but only to a short distance in comparison with the earlier weapons of the same kind that were equipped with slings. I can find no allusions or pictures to show that during this period any engine was used with a sling except the trebuchet, a post-Roman invention. All evidence goes to prove that the secret of making the skein and other important parts of a catapult was in a great measure lost within a couple of centuries after the Romans copied the weapon from their conquered enemies the Greeks, with the result that the trebuchet was introduced for throwing stones.
The catapult was gradually superseded as the art of its construction was neglected, and its efficiency in sieges was therefore decreased.
The catapults of the fifth and sixth centuries were very inferior to those described by Josephus as being used at the sieges of Jerusalem and Jotopata (A.D. 70, A.D. 67).
