The Horus name: "wsr.t-kAw
= Powerful of Kas" contains the name of the goddess "Wosret"
(wsr.t). Since in the Nebty name contains the name of the goddess of
lower Egypt, one could expect the Horus name to contains - normally placed in the in front -
the goddess of upper Egypt, Nechbet. However, it contains the name of the
local goddess from Thebes, Wosret, that was also part of
the name of Senwosret (= S'en- weseret = "Man of the goddess Wosret").Most likely the name Wosret or Weseret is a surname of Hathor.
In addition, the use of the names of two goddesses in the Nebty and in the
Horus name results in a reference to the "duality" of Egypt,
by that repeating the same notion in "The Two Ladies" (nbtj) and in
"Lord of the Two Lands" (nsw bjtj).
