The opening of the mouth ceremony (or ritual) was an ancient Egyptian ritual described in funerary texts such as the Pyramid Texts.
The ceremony involved a symbolic animation of a statue or mummy by magically opening its mouth so that it could breathe and speak. There is evidence of this ritual from the Old Kingdom to the Roman Period. Special tools were used to perform the ceremony, such as a ritual adze, an arm shaped ritual censer, a spooned blade known as a peseshkaf, a serpent-head blade, and a variety of other amulets. A calf's leg was also held up to the lips painted on the coffin.
The ancient Egyptians believed that in order for a person's soul to survive in the afterlife it would need to have food and water. The opening of the mouth ritual was thus performed so that the person who died could eat and drink again in the afterlife.
