Récréations et mathématiques mondaines au XVIIIe siècle: le cas de Guyot.

In this paper, we study the most popular book of recreational mathematics published in the second half of the 18th century: The Nouvelles Récréations by Guyot. We indicate the motivations of the author, a simple postman, and the conditions which led him to write this book. We describe the spirit of the book and the public at which it aims. The success of the Nouvelles Récréations illustrates the rise of a science in polite society whose main goal is to amaze and amuse. Then, we examine the place of mathematics in this project and analyze the repertoire of problems and tricks. We focus on problems of combinatorics proposed by Guyot, like anagrams and card shuffles, which inspired some real mathematical work on the part of Monge and Gergonne. [ABSTRACT FROM AUTHOR]
