Palermo Stone
Some scholars even believe that Neithhotep may be identical to an ominous king "Teti" listed in the Ramesside king lists and indirectly mentioned on the famous Palermo Stone. The Palermo Stone provides an interregnum between king Aha and Djer by mentioning a "double date of death" in column I of the event years. The discrepancy between the date of death for Hor-Aha and the second death note spans around 1 year, 1 month and 15 days. Such a time span seems too short for a "real" ruler such as Hor-Aha, Djer or Wadj. It would rather fit someone who ruled as a substitute for the original pharaoh. And this, in turn, is now proven for Queen Neithhotep. Thus, the ominous entry on the Palermo Stone may indeed be a reference to the interregnum of Queen Neithhotep. This would also explain as to why no contemporary artifact from the 1st Dynasty mentions the royal name "Teti", but the others ("Itetj" and "Ita").
