I've been reading through 'Theurgia Goetia' over the last couple of days and I noticed that while it suggests that you use almost the same rituals and tools as you would for Goetia, it is strangely silent on the composition of the seals. That is, there is no mention on how or from what material the seals are constructed.

As for the procedure itself, from what I've been able to gather, the practitioner uses the same 9' circle and the same preliminaries (washing, prayers, etc.) as in Goetia. The seal is likewise worn as a pendant, over the heart. Then, facing the direction assigned to the spirit, the practitioner recites the specified conjuration. In addition, there are further conjurations at the end of the text (for princes of quarters, emperors, wandering princes/dukes, and fixed point dukes). It is not yet clear to me when these additional conjurations are meant to be used.

The spirits can either appear outside of the circle (in a triangle?) or in a crystal stone (~ 4" in diameter) set upon a special seal. In some mss, this is the Solomon's secret seal, in others it's something more akin to the design in Pauline Art or Dee's Table of Practice.

Timing of the conjurations is related to Planetary hours. I'm not sure if the Moon is supposed to be waxing, as in Goetia.

So, can someone who has practiced this system clarify some of the points as to the actual execution of it? How are the seals made? How does the actual procedure go? Where/how to the spirits manifest themselves? When does one evoke?

Many thanks,
