Post funeral necromancy rituals are held for the sake of the dead and after the traditional funeral ceremony. Post funeral rituals have a purpose: to calm the souls of the dead.
Several Goetia demons can help during the post funeral necromancy rituals: Bifrons, Murmur, Bune and Samigina. Demon Bifrons is described in the Goetia, in the Pseudomonarchia Daemonum and in several other old occult sources.
Below you will find a mix of information about Bifrons and hopefully it will help you to summon this spirit.
Demon Bifrons: Goetia
Bifrons is the 46th spirit and he is ranked as an Earl. He shows up in the form of a monster, but he can take on human shape too. This spirit can teach you astrology, geometry and other arts and sciences. He will make you very knowing in the arts and sciences of your choice.
Bifrons also reveals the properties of gems and different types of wood. Moreover, Bifrons changes the placement of the dead and puts them in another place.
He rules 6 ( but actually maybe 60) legions of spirits.

Bifrons: Daemonolatry Goetia
Bifrons is a necromancy demon and he can help you to communicate with the dead. This spirit can be called upon during a funeral, because he can help the dead to leave the physical plane faster and more easily.
Bifrons can be called upon during rituals to honour and to keep in touch with dead ancestors.
