## Diophantus

(dīəfăn`təs), fl. A.D. 250, Greek algebraist. He pioneered in solving a type of indeterminate algebraic equation where one seeks integer values for the unknowns; work in this field is known as Diophantine analysis. Only 6 of the 13 books with which he is credited are extant. The standard edition in Greek was edited by Paul Tannery (2 vol., 1893–95).
