 The reign of Djedkare Isesi heralded a new period in the history of the Old Kingdom . First , Djedkare Isesi did not build a sun temple , as his predecessors had done since the time of Userkaf , some 80 years earlier . This may be a result of the increased prominence of Osiris compared with the sun god Ra during the late Fifth Dynasty . The importance of this cult becomes manifest when the Pyramid Texts of the pyramid of Unas are inscribed a few decades later . In this context , it is perhaps noteworthy that the only known statue of Djedkare Isesi was discovered in the ruins of the temple of Osiris , in Abydos . Another manifestation of the winds of change during Djedkare 's time on throne is the confirmation of the relocation of the royal necropolis from Abusir , where it had been since the reign of <unk> , to Saqqara , where Menkauhor Kaiu , Djedkare and his successor , Unas , built their pyramids . Abusir may have become overcrowded by the time of Menkauhor 's accession and the capital may have been shifted south to Saqqara along with the royal necropolis around the same time . The abandonment of Abusir as a royal necropolis and the termination of sun temple building are possibly related given the close association between the two since the reign of Userkaf .
