A while back I had taken the time to draw out this description of Andrew's altar. You can really feel his style through how he sets up the space. Made up of two separate altars: the High Altar and the working altar, they each serve a different purpose.
But, both heavily emphasise the images, icons and bodies of the various entities within the spiritual congress. The positioning of the different items have various meanings, perhaps how he arranged the fetishes on the working altar depended on the season (or other specific timing).
The double altars can represent the double nature of the sabbatic space, the seen and unseen circle.
Rereading through all this helped inspire my own interpretation of the double altar space. Shown in the second design, I spent time infusing my other practices into the design. On the top surface, the elemental weapons are placed around the altar - each placed at a specific point of the 8 pointed star. The Fetish Tree (Stang) is inserted in the center, where I would hang charms, talismans, amulets, etc.
Inside, there is a second 8 pointed star that would house the fetishes inside - each positioned at a point. The idea that I could rotate them below depending on the working. By condencing the altars in this way, it is easier to house the altar in the center of the circle (my preferred altar spot).
I'll be hunting for some good candidates for the project, hopefully I can find something fitting.
