Catacombs of Kom El-Shoqafa. Bearded serpents wearing the double crown of Egypt, with Medusa heads in the medallions above, flank either side of the tomb's entrance. Here is a picture of one. Each serpent is holding the pine cone of Dionysis and the staff of Hermes. Thus, we have an ancient Egyptian form of death ritual, mummification, represented along with a symbolic invocation of Greek gods for the protection they can offer the deceased.
