Created by Oberon Zell-Ravenheart, this mandala diagrams the correspondences between sacred symbols and the movement of time through the year.

"All of the various magickal systems of correspondences can be diagrammed on the Magick Circle, which is read like a clock face. This is done by over-laying a series of polygrams, with their points evenly spaced around the Circle, as at the numbers on the clock. Outer concentric circles are then divided into the appropriate number of segments, just like the hours and minutes on a clock face. And like the hands of a clock, time as well as magickal work moves through each of those segments sequentially (one after another) in a Dance of the Hours." - Grimoire for the Apprentice Wizard, Oberon Zell-Ravenheart

The design features in the center a solar cross overlaid with a pentagram and a septagram. The first inner rung is planetary days, and next layered the monthly signs of the Zodiac. The outer layer is the Druidry-inspired glyphs from "Calendar of the Trees", by Robert Graves.
