Although it looks like Latinism, (crepida -ae , sandalia ), it is an Anglicanism, as the term was created in the first quarter of the nineteenth century by the English humanist writer William Hazlitt who commented on this expression of Pliny the Elder that was attributed to the Greek painter of the 4th century a. C. Colophon appeals : Ne supra crepidam sutor iudicaret : That the shoemaker does not pee above the sandals , ( shoemaker, to your shoes). So Apeles told a shoemaker who started criticizing the sandals in a painting and went on in more detail. The term refers to individuals who have apparent authority over everything and have no knowledge of anything.
