Anubis
On both sides of the sarcophagus, behind the sons of Horus, we can see Anubis (see the additional image), the jackal-headed god associated with mummification and the transition to the afterlife. This is meant to ensure that Anubis stands by the deceased during his journey to the afterlife. Anubis is often depicted on sarcophagi and coffins while accompanying the deceased.
Both portrayals of Anubis give him a different title. The title of Anubis on the left side of the sarcophagus is He who is in the Place of Embalming. This refers to the role of Anubis in the mummification process. The title of Anubis on the other side of the sarcophagus is Foremost of the Divine Booth. This title probably refers to either the burial chamber or the embalming booth.
Let us continue our journey from the other angle.
