Anubis’ sacred plant is the cypress, a tree that Greeks as well as the Egyptians associated with death and mourning. Cypress oil is a great offering, and burning it during ritual is very effective. He prefers strong incense, especially myrrh, cedarwood, and the traditional frankincense. Beer and bread is the standard offering to pretty much any Egyptian God, and He will accept it, but I’ve discovered that He likes strong liqueur, especially rum, much better. Cool water, the traditional Egyptian drink of the dead, is also a good libation. More than one modern Kemetic says He seems to likes spicy food and dark, bitter chocolate.
As a way-walker along the lines of Hekate and Hermes, He likes locks and keys. I’m told by a Kemetic that hematite, obsidian, and tiger’s eye are the stones He likes. His colors are black and gold, and in fact He is sometimes called The Black and Gold God. Since Sirius is His star, images of stars of other celestial phenomenon would be very appropriate. The number nine is possibly sacred to Him, as He was known for defeating the Nine Bows of Egypt.
But don’t forget to honor Him with Your actions. Honor the dead and your ancestors. Leave flowers on a stranger’s grave. Practice some kind of divination or magic, even if it is only privately. Support causes that help orphans and the homeless. Act as a guide to others in some way.
