The Search for the Prisca Theologia.
“These great and good men promulgated the idea of an ongoing, beneficent magic available to certain men of every age for the collective use of mankind. The Latin for this is prisca theologia, secret wisdom. The odd thing is that this belief in a secret wisdom is not the Rosicrucians’ alone. We know in London in the middle of the same century of the existence of a society called the Invisible College. Its members were reputed to be the very carriers of the beneficent magic I speak of.
You of course do not know of the writings of Giordano Bruno, of which here is a specimen page in his own handwriting. My scholars have traced for me, like the best detectives, the existence of this idea and of various mysterious organizations to maintain it, in most of the Renaissance cultures, in medieval societies and in ancient Greece.
I hope you are following this closely. The earliest recorded mention of special people born in each age to ease the sufferings of humankind with their prisca theologia comes to us through the Greek in the translated writings of the Egyptian priest Hermes Trismegistus. It is Hermes who gives the historical name to this occult knowledge. It is called the Hermetica.”
