The Seal of A∴A∴
This seal is arranged in a heptagram, with the name BABALON written in each corner. This name adds to the number 156, represented by the formula inside of the heptagram.
The border, Sigillum Sanctum Fraternitatis A∴A∴, translates to “The Holy Seal of the Fraternity of A∴A∴.” The X in the Circle is something Crowley calls the “Sign of N.O.X.” This symbol is described in Liber 418, in the 6th Aethyr:
“And there is writing in Greek above that. The word “nox” written in Greek, and a circle with a cross in the centre of it, a St. Andrew's cross.”
77+((7+7)/7)+77
Which also adds to 156. The border, Sigillum Sanctum Fraternitatis A∴A∴, translates to “The Holy Seal of the Fraternity of A∴A∴.” The X in the Circle is something Crowley calls the “Sign of N.O.X.” This symbol is described in Liber 418, in the 6th Aethyr:
“And there is writing in Greek above that. The word “nox” written in Greek, and a circle with a cross in the centre of it, a St. Andrew's cross.”
I personally have some theories on what A∴A∴ stands for. There are three options, (for the three Colleges):
Aurorae Aureae: “Golden Dawn” in Latin.
Arcanum Arcanorum: “Secret of Secrets” in Latin.
Astrum Argenteum: “Silver Star” in Latin.
