Dynasty king, with only two seals and a few seal impressions bearing his name known as of 2017, a paucity of attestations suggesting a very short reign. This is also supported by the state of Shepseskare's unfinished pyramid, which "was interrupted [and] corresponds to the work of several weeks, perhaps no more than one or two months". Fourthly, archaeological evidence also favors dating Shepseskare's reign to after Neferefre's. Some of the few seal impressions bearing Shepseskare's name have been discovered in the oldest part of Neferefre's mortuary temple, which was not built until Neferefre's death. This seems to indicate that Shepseskare made offerings for the funerary cult of Neferefre, who must therefore have reigned before him. Another argument concerns the alignment of pyramids of Sahure, Neferirkare Kakai and Neferefre: they form a line pointing to Heliopolis, just as the three pyramids of Giza do. In contrast, Shepseskare's unfinished pyramid does not fall on the line to Heliopolis, which strongly suggests that Neferefre's pyramid had already been in place when Shepseskare started to build his. Lastly, while Shepseskare is noted as the immediate predecessor of Neferefre in the Saqqara king list, Verner notes that "this slight discrepancy can be attributed to the [political] disorders of the time and its dynastic disputes." Verner's arguments have convinced a number of Egyptologists, including Darrell Baker, Erik Hornung and Iorwerth Edwards. Reign duration While Neferefre is given a reign of some 20 years in epitomes of Manetho's Aegyptiaca, the current academic view is that this number is an overestimation of his true reign length, which must have been significantly shorter. Before the results of the extensive excavations in Abusir were fully published, Egyptologists following the traditional succession hypothesis credited Neferefre with around a decade of rule, based on the paucity of attestations contemporaneous with his reign. For example, von Beckerath and Winfried Barta gave him 11 and 10 years on the throne, respectively. This view now has few supporters. Indeed, since then, Verner has set forth the hypothesis of a reign of no more than two years. His conclusion is based on archaeological evidence: the unfinished state of his intended pyramid, and the general paucity of documents datable to his rule. Verner writes that: The shape of the tomb of Neferefra...as well as a number of other archaeological finds clearly indicate that the construction of the king's funerary monument was interrupted, owing to the unexpected
