c. 1680-c. 1620 B.C.

Egyptian scribe credited with writing down the material on the Rhind Papyrus, named for Alexander Henry Rhind, the Scottish Egyptologist who discovered it in 1858. A secretary rather than author, as he himself stated in the manuscript, Ahmes indicated that he was recording mathematical information from an earlier work, one dated to perhaps 2000 B.C. The Rhind Papyrus contains 87 problems in basic arithmetic, and illustrates simple fractions.
