• The Opening of the mouth ceremony (or ritual): an ancient Egyptian ritual described in funerary texts such as the Pyramid Texts. The ritual involved the symbolic animation of a statue or mummy by pretending to open its mouth so that it could breathe. Sometimes special tools were used to open the mouth. One of these was a sort of adze made from meteoric iron. The Opening of the mouth ceremony was performed so that the person could speak and breathe in the afterlife. http://en.wikipedia.org/wiki/Opening_of_the_mouth_ceremony
