The Lahun IV, I papyrus is definitely dated to Year 1 of the second 13th Dynasty king, Sekhemkare and mentions that a daughter was born in the regnal Year 40 to Sent, the daughter of Nehktisonb. None of the early 13th Dynasty kings ruled for 40 years, therefore the texts refer to the reign of an earlier king. The Turin canon tells us Amenemhat III is the only ruler of the period to have reigned in excess of 40 years.
