Pierre Forcadel of Beziers [died 1574], protégé of Ramus, was professor of mathematics in the Collège Royal, Paris in 1560. He was the first to teach mathematics in the French language. He also wrote on astronomy and translated the works of several Greek mathematicians, notably producing the first French Euclid, published by Cavellat in 1564. Smith describes this work here ‘perhaps the most elaborate French treatise on arithmetic published in the 16th century’. Relying on the recent algebra of Cardano and Stifel’s calculus, Forcadel gives a theoretical account of arithmetical calculations and rules, comparable to Tunstall and Tartaglia. A sophisticated work in the theory of arithmetic, the book is an unusually fine example of 16th century French book design, with complicated equations laid out in fine configurations.
