Authorship of the Edwin Smith Papyrus is debated.[by whom?] The majority of the papyrus was written by one scribe, with only small sections copied by a second scribe.[1] The papyrus ends abruptly in the middle of a line, without any inclusion of an author.[2]:71 It is believed that the papyrus is an incomplete copy of an older reference manuscript from the Old Kingdom, evidenced by archaic grammar, terminology,[3] form and commentary. James Henry Breasted speculates - but emphasises that this is pure conjecture based on no evidence - that the author might be Imhotep, an architect, high priest, and physician of the Old Kingdom, 3000–2500 BCE.[10]:9
