The Rhind Papyrus (also called the Ahmes Papyrus) is named after the British collector, Rhind, who acquired it in 1858. It was copied by a scribe, Ahmes (or Ahmos), (~1650 BC) from another document written ~2000 BC, which, possibly in turn, was copied from a document from ~2650 BC (the time of Imhotep?). The Rhind Papyrus is located in the British Museum, and contains mathematics problems and solutions.
