The Simon Necronomicon‘s Book of Entrance begins as follows:
This is the Book of Entrance to the Seven Zones above the Earth, which Zones were known to the Chaldeans, and to the ancient races that preceded them among the lost temples of UR. Know that these Zones are governed by the celestial spirits, and that passage may be had by the Priest through those lands that border on the Unzoned Wastes beyond…
This cosmology serves as the foundation of the Necronomicon‘s Gatewalking ceremony. Each of the seven spheres above us is tied to a particular Mesopotamian deity, to which corresponds a particular planet. The magician must pass through each of the seven stages of the cosmos through a period of fasting and a mystical rite of walking requiring a seal of the gate, a drawing upon the ground, and an incantation to be said while performing the walking. This is something of a simplification, but it presents the essential outlines.
I’ve talked about one of the likely sources of Simon’s ritual – the Fourth Book of Occult Philosophy – in a previous post. What I’d like to do now is to answer another question: does the cosmology of the Necronomicon reflect that of ancient Mesopotamia?
We’ll look at that next time.
