The Edwin Smith Papyrus is named after its original owner, Edwin Smith, an American Egyptologist (1822–1906) who purchased it in Luxor in 1862. On the basis of the handwriting, it has been dated to about 1600 B.C., but on the basis of language (and errors in transcription), the work is believed to be a copy of another text that was written some three centuries earlier. The work includes descriptions, examination procedures, diagnoses, and practical treatments for forty-eight distinct injuries, beginning at the top of the head and ending at the shoulder blades and chest. The injuries listed are consistent with those sustained in war or construction. There are three categories of injuries—"an ailment I will handle" (describing injuries for which a known cure existed); "an ailment I will fight with" (denoting one whose treatment was less certain); and "and ailment for which nothing is done" (meaning one for which no practical treatment was known).
