Celt
Celt, a generic term, now obsolescent, for stone implements shaped like chisels and used as cutting instruments. The word is derived from what is generally considered to be a pseudo-ablatival Latin form, celte, in the Vulgate (Job xix. 24) translated "with a chisel." No other form of the word is known, so that it is probably a miswriting for certe - certainly, verily - corresponding to the "forever" of the Authorised Version. The term has been extended to include implements and weapons of the Bronze Age (q.v.), which were at first copies of, and then improvements on, those of the earlier races, for metal was capable of being worked into shapes which the stone would not admit of.
