I discovered that the seals for the archangels of the tree of life as found within the book "Summoning Spirits" by Konstantinos, is from their material. Before this I had never seen proper seals, other than RC, for this class of spirits. From experience I have found these seals to be spot on and work extremely well.
Looking further into the AS material I discovered seals for the classic seven planetary angels. Very similar in appearance to the traditional ones as found in Agrippa, but slightly altered. The traditional seals have always worked fine, but again was delighted to find these newer ones were superior.
Recently I have been playing around with what they call the "presigillums"
Example below:
They seem to use them as planetary focal points, rather than use the alchemical / astrology symbols. Additionally they are the starting point for drawing sigils using the planetary squares.
Like so:
Yet again, I have found them remarkable. I have yet to determine the source of these seals and presigillum, my best guess is whoever the scryer or evoker for the order was, they must have been very very good.
Has anyone else worked with these in any degree or have any information to share upon them?
