Identify the Goddess

You find another puzzle in the corner of the stone room but containing only two images and a quote.
Hm, the images do look a little similar...


"O my Goddess, stretch Yourself over me, that I may be placed among
the imperishable stars which are in You,
and that I may not die"

Who is she?

(3 letters)

Goddess Nut? You wonder what does a sky goddess have to do with you being trapped in a room...
You find this puzzle to be more memorable than the others. You remember these images for later use.
This puzzle also unlocks a clue: Search for the Pharaoh.
