The Origin of the Cult of Horus
in Predynastic Egypt - Page 9
Alfred Grimm and Sylvia Schoske, Am Beginn der Zeit, Ägypten in der Vor- und Frühzeit; Ausstellungskatalog, Heft 9, Schriften aus der Ägyptischen Sammlung (SAS); München, Staatliches Museum Ägyptischer Kunst, 24.12. 2000 - 22.4.2001, pp. 2, 11, write:
"The name "Schemesu-Hor" applied to the early kings in the Turin Canon of Kings can be understood quite literally as "Followers of Horus". Neither the number nor sequence of the kings who ruled from "Falcon" to Narmer, the so-called "Dynasty 0", is known exactly at the present time, but one can possibly equate them with the sovereigns having the double crown on the Palermo stone (and its fragments) as well as with the demigods who ruled before First Dynasty."

The predynastic period of the falcon cult (Figure 3) is testified to by many predynastic "falcon serekhs" (serekh = king’s name enclosure) in Egypt, all originating from the period about 3300 to 3100 BC.
