KW - Blaise Pascal KW - ciron KW - mite AB - The identity of Blaise Pascal’s mite is examined. Linguistics, morphology, habitat and size reveal that Pascal’s mite is not Acarus siro L., as usually thought, but Sarcoptes scabiei (L.). The diachronic use of the popular term ciron is explored from a number of different perspectives. In everyday language and in Pascal’s time, the term used to designate A. siro L. was mite (used singly, in English and French) and not ciron, a word restricted to the scabies mite; its use is also investigated. The classification of mites in the 17th and 18th centuries is reviewed. ER -
