Word Origin & History
1715, from L. ghost word (apparently a misprint of certe) in Job xix:24 in Vulgate: "stylo ferreo, et plumbi lamina, vel celte sculpantur in silice;" translated, probably correctly, in KJV as, "That they were graven with an iron pen and lead in the rock for ever." But assumed to be a genuine carving
tool, since it was in the Bible, and adapted by archaeologists for a class of prehistoric implements.
1607, from L. Celta, singular of Celtæ, from Gk. Keltoi, Herodotus' word for the Gauls (who were also called Galatai). Used by the Romans of continental Gauls but apparently not of the British Celtic tribes.
