The Serdab - Saqqara Step Pyramid, Egypt

The Polaris Position - facing North from the Serdab.

The Serdab was a sealed off room in a tomb in which a statue of the deceased was placed. These statues were vessels that the soul could inhabit. Djoser's Serdab is located here, on the North side of the Step Pyramid.. A statue depicting the king wearing the Sed Festival robe was discovered inside (the original is in the Egyptian Museum and is replaced by a duplicate copy).
​
Two holes made through the wall directly face the King's gaze allowing the King to peer through and see the rituals and festivals taking place in the court before him. These holes also allowed the king to look north, the cardinal point towards which, his entire pyramid complex is oriented. This is the location of Polaris and the other circumpolar stars in the Northern Sky, his ancestor, whom he hoped to join. These stars never set below the horizon, which was seen as a sign of immortality. Djoser was thus poised to join his forefathers in everlasting life.
