The ancient Egyptians believed that the false door was a threshold between the worlds of the living and the dead and through which a deity or the spirit of the deceased could enter and exit. The false door was usually the focus of a tomb's offering chapel, where family members could place offerings for the deceased on a special offering slab placed in front of the door. Most false doors are found on the west wall of a funerary chapel or offering chamber because the Ancient Egyptians associated the west with the
land of the dead. In many
mastabas, both husband and wife buried within have their own false door.
Structure A false door is usually carved from a single block of stone or plank of wood, and it was not meant to function as a normal door. Located in the center of the door is a flat panel, or niche, around which several pairs of
door jambs are arranged—some convey the illusion of depth and a series of frames, a foyer, or a passageway. A semi-cylindrical drum, carved directly above the central panel, was used in imitation of the reed mat that was used to close real doors. The door is framed with a series of mouldings and lintels as well, and an offering scene depicting the deceased in front of a table of offerings is usually carved above the center of the door. Rarely, the Old Kingdom false door was combined with statues, demonstrating the common ancestry of the false door and
naos in similar early ancient Egyptian architectural features. During the nearly one hundred and fifty years spanning the reigns of the sixth Dynasty pharaohs
Pepi I,
Merenre, and
Pepi II, the false door motif went through a sequential series of changes affecting the layout of the panels, allowing historians to date tombs based on which style of false door was used. The same dating approach is used also for the First Intermediate Period. After the
First Intermediate Period, the popularity of the false doors diminished, being replaced by
stelae as the primary surfaces for writing funerary inscriptions. Here, the false door is represented by two wooden doors that are secured with door bolts, bracketed on both sides by architectural niching – recalling earlier niched temple and palace façades such as the enclosure wall that surrounds the mortuary complex of king Djoser of the Third Dynasty. In a similar manner to the Old Kingdom false doors, representations of false doors on Middle Kingdom coffins facilitated the movement of the deceased's spirit between the afterlife and the world of the living.
Inscriptions The side panels usually are covered in inscriptions naming the deceased along with their titles, and a series of standardized
offering formulas. These texts extol the virtues of the deceased and express positive wishes for the afterlife. For example, the false door of Ankhires reads: The lintel reads: The left and right outer jambs read: ==Prehistoric Sardinia==
