An old friend of mine who is an expert in astrology (among other things) was visiting and explained some aspects of astrology I was not familiar with by sketching out a small diagram that was the basis for this painting.
I included in this chart (from the outermost circle and going inward) the names of the Jewish months and human aspects associated with them, from Sefer Yetzirah;
whether this sign is cardinal, fixed or mutable (the first, middle or last month of the season); the names of the astrological signs;
whether it is a fire, earth, air or water sign;
the first four months of this 12-month cycle is 'primal' associated with embryonic development of self, the next four are 'individual' associated with developing one's individual personality, and the last four months are 'universal' associated with a self that is involved with world-centric global concerns;
the Hebrew letter from the Twelve Simple letters of Sefer Yetzirah that are associated with the months;
and finally the seasons.
