International audience The powerful vizier Useramun was in office from year 5 to year 28 or 34 of the reign of Tuthmosis III, succeeding his father, Ahmose Aametu. A text referring to his appointment by the king is preserved on the verso of papyrus Turin Cat. 1878. Although this text was already known to Champollion, no indepth study of it has been carried out since the publication of its first copy by Pleyte and Rossi in 1869-1876 and of its first transcription and translation by Helck in 1955.Here the author presents a new facsimile and study of the text, clarifying several palaeographic issues and shedding further light on the meaning of this rather enigmatic composition, which has no known parallel in Egyptian literature, but echoes a scene in Useramun's tomb (TT 131), showing the vizier Ahmose Aametu introducing his son Useramun to the king, who appoints him as his father's successor.The text on the Turin papyrus also raises questions about the theme of circumcision and the use of the metaphor of silver and gold to designate the vizier and the king, respectively. The composition is a Ramesside historical fiction, most likely written during the first half of the Twentieth Dynasty, when the memory of the vizier Useramun evidently still loomed large.
