From wikipedia.org:
Anubis is the Greek name[1] for a jackal-headed god associated with mummification and the afterlife in Egyptian mythology. In the ancient Egyptian language, Anubis is known as Inpu, (variously spelled Anupu, Ienpw etc.)[2]. The oldest known mention of Anubis is in the Old Kingdom pyramid texts, where he is associated with the burial of the king.[3] At this time, Anubis was the most important god of the Dead but he was replaced during the Middle Kingdom by Osiris.[4]
He takes various names in connection with his funerary role, such as He who is upon his mountain, which underscores his importance as a protector of the deceased and their tombs, and the title He who is in the place of embalming, associating him with the process of mummification.[3] Like many ancient Egyptian deities, Anubis assumes different roles in various contexts, and no public procession in Egypt would be conducted without an Anubis to march at the head.
