Neferefre's first or second year on the throne, and his third year at the very latest. Finally, a few artefacts dated to Neferefre's rule or shortly after have been uncovered in his mortuary complex and elsewhere in Abusir, such as clay seals bearing his Horus name. Some of the Abusir Papyri discovered in Khentkhaus II's temple and dating to the mid- to late Fifth Dynasty mention the mortuary temple and funerary cult of Neferefre. They constitute a written source near-contemporaneous with his reign, which not only confirmed the existence of Neferefre's pyramid complex at a time when it had not yet been identified, but also gives details regarding the administrative organisation and importance of the funerary cult of the king in Ancient Egyptian society. Historical Neferefre is present on several Ancient Egyptian king lists, all dating to the New Kingdom period. The earliest such list mentioning Neferefre is the Abydos King List, written during the reign of Seti I (fl. 1290–1279 BC), and where his prenomen occupies the 29th entry, between those of Neferirkare Kakai and Nyuserre Ini. During the subsequent reign of Ramses II (fl. 1279–1213 BC), Neferefre appears on the Saqqara Tablet, this time after Shepseskare, that is as a second successor to Neferirkare Kakai. Owing to a scribal error, Neferefre's name on this list is given as "Khanefere" or "Neferkhare". Neferefre's prenomen was in all probability also given on the Turin canon (third column, 21st row), which dates to the same period as the Saqqara tablet, but it has since been lost in a large lacuna affecting the document. Nonetheless, the part of the reign length attributed to Neferefre by the canon is still legible, with a single stroke sign indicating one year of reign to which a decade could in principle be added, as the corresponding sign would be effectively lost in the lacuna of the document. Neferefre was also likely mentioned in the Aegyptiaca, a history of Egypt written in the 3rd century BC during the reign of Ptolemy II (283–246 BC) by the Egyptian priest Manetho. No copies of the Aegyptiaca have survived to this day and it is now known only through later writings by Sextus Julius Africanus and Eusebius. Africanus relates that the Aegyptiaca mentioned the succession "Nefercherês → Sisirês → Cherês" for the mid-Fifth Dynasty. Nefercherês, Sisirês and Cherês are believed to be the hellenized forms for Neferirkare, Shepseskare and Neferkhare
