COR'AX (κόραξ). A Greek word, which occurs in a Latin form in Vitruvius, but only as a translation from Diades, who merely mentions it as the name of one of the military engines employed in the attack of fortified places, observing, at the same time, that it was very inefficient, and not worth the trouble of describing. (Vitruv. x. 13. 8.) Polybius also gives the same appellation to an engine employed by the Romans on board ship, and describes at length the manner in which it was constructed and applied. Polyb. i. 22.
