Saqqara (Saqqâra). Step Pyramid of Neterikhet (Djoser).
'The Pyramid of Sakkara has been thought to be of the first dynasty by Mariette, but without any proof; its being so much like the pyramid of Medum, and unlike any other, makes it most likely at least to belong to a time before the fourth dynasty.
The finished coats of casing inside the structure are very important, shewing repeated additions; the innermost now visible is almost in the middle of the South face, and shews the pyramid to have been mainly added to on the West and North, and to have been not half the size at first that it is now; yet as the chamber is under the middle, that seems to have been made later than the pyramid.
None of the final casing remains visible, & all the earlier casings are seen in section.'
