CHUQUET, NICOLAS French mathema tician, was born at Paris. He studied and qualified in medicine, probably at Lyons. In 1484 he wrote a work on arithmetic, Tri party en la science des nornbres. This was circulated in manu script form and was first printed in 1880. The first part deals with rational numbers, the second with irrational numbers and square roots, and the third part is a study of equations. The Triparty was very largely used and its influence can be traced in the Arith metic of de la Roche.
