- Serdab -
Serdab is the modern Arab name meaning "cellar" used to denote a funerary chapel in a mastaba dating to the Old Kingdom that held a statue of the Ka of the deceased. This chapel would normally be blocked for the outside world. One or more holes or a narrow slit in the wall directly in front of the face of the statue would allow the Ka to leave the serdab and to let the offerings presented to it to pass into the serdab.
The best known example of a serdab was found at the North side of the Step Pyramid of Djoser at Saqqara. It contained the famous statue of this king, now at the Egyptian Museum in Cairo. From the 4th Dynasty on, serdabs were also built for private persons.
