Djedkare is attested in four ancient Egyptian king lists , all dating to the New Kingdom . The earliest of these is the Karnak king list , dating to the reign of Thutmose III ( 1479 – 1425 BCE ) , where Djedkare is mentioned on the fifth entry . Djedkare 's prenomen occupy the 32nd entry of the Abydos King List , which was written during the reign of Seti I ( 1290 – 1279 BCE ) . Djedkare is also present on the Saqqara Tablet ( 31st entry ) where he is listed under the name " Maatkare " , probably because of a scribal error . Djedkare 's prenomen is given as " Djed " on the Turin canon ( third column , 24th row ) , probably because of a lacuna affecting the original document from which the canon was copied during the reign of Ramses II ( 1279 – 1213 BCE ) . The Turin canon credit Djedkare with 28 years of reign .
