I would not call them "ancient crossbows". They were ballista, working with a different mechanism, the torsion. The crossbows was known (it is not much different from a bow, concerning the engine), but the torsion was considered more effective. Anyway we have some findings related catapults/ballista. For what I remember a metal components of the Ampurias Catapult (found in 1912 in the Neapolis of Ampurias). But there are severl findings concerning the metal part of that ballistae.
