Word Origin & History
1287, cobelere "one who mends shoes," of uncertain origin. "The cobbler should stick to his last" (ne sutor ultra crepidam) is from the anecdote of Gk. painter Apelles. [The quote is variously reported: Pliny ("Natural History" XXXV.x.36) has ne supra crepidam judicaret, while Valerius Maximus (VIII.xiii.3)
gives supra plantam ascendere vetuit.] The meaning "pie" is Amer.Eng. 1859, perhaps related to 14c. cobeler "wooden bowl."
