Why do enbarmes Wear Masks of Anubis Mummy fiing?

Embalmers in ancient Egypt would wear the mask of Anubis, the priest was than thought to have become the god himself. The 'Opening of the Mouth' ceremony was then performed. It consisted of a number of rituals that would turn the mummy (or a statue of the dead) into an inhabitable vessel for the deceased's ka.

The ceremonies involved purification, sensing and anointing of the mummy along with incantations. The mummy was touched by ritual objects on various body parts to restore the senses - the spirit would then be able to see, hear, speak and eat as a living being. Some of the tools for this ritual have been found in predynastic Amratian graves, so it is probable that at least some of the rituals involved in the 'Opening of the Mouth' had evolved from this early time.

After the deceased had been placed into the tomb and sealed up, it was thought that Anubis would lead the deceased to the afterlife, along with another god, Wepwawet (Upuaut).
