 In addition to these sources , Djedkare is mentioned on the Prisse Papyrus dating to the 12th Dynasty ( c . 1990 – 1800 BCE ) . The papyrus records The Maxims of Ptahhotep and gives Djedkare 's nomen " Isesi " to name the pharaoh whom the purported authors of the maxims , vizier Ptahhotep , served . Djedkare was also probably mentioned in the Aegyptiaca , a history of Egypt written in the 3rd century BCE during the reign of Ptolemy II ( 283 – 246 BCE ) by the Egyptian priest Manetho . No copies of the Aegyptiaca have survived to this day and it is known to us only through later writings by Sextus Julius Africanus and Eusebius . Africanus relates that a pharaoh " Tancherês " ( Ancient Greek Τανχέρης ) reigned for 44 years as the eighth and penultimate king of the Fifth Dynasty . Given its position within the dynasty , Tancherês is believed to be the Hellenized name of Djedkare Isesi .
