In 1879 expert opinion was unanimous in rejecting Sautuola's timid suggestion that the ceiling paintings in his family's cave were made by the same prehistoric hunters whose stone and bone artifacts he had been collecting from the cave floor.

Word History

Etymology

Adjective

Middle English autentik, auctentyke, borrowed from Anglo-French & Medieval Latin; Anglo-French autentik, autentique, borrowed from Medieval Latin autenticus, authenticus, auctenticus "original, genuine (of a document), authoritative, approved by authority," going back to Latin authenticus "original (of a document)," borrowed from Greek authentikós "warranted as genuine, original, authoritative," probably from authentía "absolute sway, authority" (from authéntēs "doer, master" + -ia -ia entry 1) + -ikos -ic entry 1; authéntēs, in earlier Greek "killer, murderer, perpetrator of a deed," from aut- aut- + -hentēs, from hen- (going back to Indo-European *senh₂-, full-grade ablaut of zero-grade *sn̥-ne-h₂, whence Greek ánymi, anýnai "to complete, achieve, perpetrate") + -tēs, agent suffix

Note: Greek authentikós and authentía/-eía first appear in non-literary sources of the first centuries A.D., whence their adaptation into Latin, and go on to see considerable elaboration in patristic and Byzantine Greek. The base of these words, the agent noun authéntēs, had rather disparate senses in ancient Greek. The earliest, attested in Herodotus and the Attic tragedians, is "killer, murderer," apparently generalized in Hellenistic Greek to "perpetrator (of a crime)" and then "doer, master," whence the derivatives based on the notion of authority. The etymological sense of the word, however, supported by Sophocles' autoéntēs, is "person accomplishing something on their own," which is not far from the later meaning "doer." The specific application to murder was perhaps originally a euphemism or a legal usage, or, somewhat less likely, by association with the verb theínein "to strike, kill." — Several Indo-European congeners of Greek ánymi have been proposed, as Sanskrit sanóti "(s/he) gains, obtains," ásanat "has gained," Avestan hanāt̰ "will obtain," Hittite šanḫ- "seek, look for" (see further in Lexikon der indogermanischen Verben).
