Opening of the Mouth
This is an elaborate ritual performed on deceased kings by their sons to legitimate heritage. Thereby statues and mummies were transformed into vessels for the Ka. Could be done on the burial chamber as well as on newly created items in the workshops.
It includes purification, incensing, anointing, incantations and touching certain parts of the mummy with a tool resembling a sculptorīs chisel, like the mouth, eyes, ears, nose etc so that eating, sight, hearing, smelling etc, would be restored.
At the ritual opening of a newly built temple, this ritual was performed on walls, doors, etc, and on all cult statues of deities which were placed in the temple, all in order for the deities to take place within the structure or statue.
In Mirjam Lichtheimīs 'Anicent Egyptian Literature', vol II, the New Kingdom, p 120 is a: "Formula for opening Nīs mouth in the necropolis. He shall say:"
My mouth is opened by Ptah,
My Mouthīs bonds are loosed by my city-god.
Djehuty has come fully equipped with spells,
He looses the bonds of Seth from my mouth.
Atum has given me my hands,
They are placed as guardians.
My mouth is given to me,
My mouth is opened by Ptah
With that chisel of metal
With which he opened the mouth of the gods.
I am Sekhmet-Wadjet who dwells in the west of heaven,
I am Sahyt among the souls of On.
As for any spells, any spells spoken against me.
The gods shall rise up against them,
The entire Ennead, the entire Ennead!
