Celt (pron. //) is an archaeological term formally used to describe long thin prehistoric stone or bronze adzes and other axe-like tools and hoes. Its use came about from a misreading of Job 19:24 in the Sixto-Clementine edition of the Latin Vulgate Bible where the certe in Stylo ferreo, et plumbi lamina, vel certe sculpantur in silice was read as celte. A 'Celte' was wrongly assumed to be a type of ancient chisel, when in fact it was a misspelling of the word certe "indeed."
