 Finally , the successor of Djedkare , Unas , is thought to have been his son in spite of the complete lack of evidence bearing on the question . The main argument in favor of this filiation is that the succession from Djedkare Isesi to Unas seems to have been smooth , as suggested indirectly , for example , by the Abusir papyri . <unk> evidence also comes from the reliefs of Unas ' causeway , which show many officials bearing names incorporating " Isesi " , suggesting at the very least that Unas did not perceive Djedkare as an antagonist .
