"The 19th century in France spawned numerous ''fous litteraires, one of them being Jean-Pierre Brisset (1837-1919). An individualist among individualists, he dismantled the existing French tongue, reshaping it to suit his own grandiose purposes, which were to explain afresh the development of human beings (from frogs) and of their language (from croaks). Continuous and ubiquitous punning was a unique feature of his writing. In this study, Redfern examines such themes as the nature of literary madness, the phenomenon of deadpan humour, the role of analogy, and the place of institutional religion in Brisset''s creative rewriting of the creation."
