Celt-Iberian (adj.)

"stone chisel," 1715, according to OED from a Latin ghost word (apparently a mistake 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 by others to be a genuine carving tool, partly because it was in the Bible, and thereafter adapted by archaeologists as a name for a class of prehistoric implements.

from Latin Iberia, the ancient name of the large southwestern peninsula of Europe, from Greek Iberes, the name of a Celtic people of ancient Spain. An identical name was given to an Asiatic people near the Caucasus in what is now Georgia. Of unknown origin in both uses, but the word as applied in Spain is believed to be related to that of the River Ebro. Related: Iberian (c. 1600 as a noun; 1610s as an adjective).
