La Très Sainte Trinosophie: 18th c. French occult tome

Bibliodyssey, a site devoted to rare old books and materia obscura, is one of my favorite blogs. Each page-load is like a peek into the most treasured recesses of an eccentric book-hoarder's stash. I have a tiny attention span and an aversion to collecting too many objects, so for me it's a dream come true. Here's a snip from today's entry, "La Très Sainte Trinosophie," which includes some pages of cool old magic code I don't understand:

The 'Cosmic Master of the Age of Aquarius' and mysterious adept, the Count de Saint-Germain, allegedly died in 1784. He was a spy, virtuoso violinist, diplomat, friend at the Court of Louis XV, adventurer and was said to be able to transform iron into gold. A veritable procession of people have claimed to be the still living Count de Saint-Germain since 1784.
"During the centuries after his death, numerous myths, legends and speculations have surfaced. He has been attributed with occult practices like snake charming and ventriloquism. There are stories about an affair between him and Madame de Pompadour. Other legends report that he was immortal, the Wandering Jew, an alchemist with the elixir of life, a Rosicrucian or an ousted king, a bastard of Queen Maria Anna of Spain, that he prophesied the French Revolution. Casanova called him the violinist Catlini. Count Cagliostro was rumored to be his pupil."
Either the Count de Saint-Germain or Cagliostro is considered to be the author of 'La Très Sainte Trinosophie' (The Most Holy Three-fold Wisdom), from the latter half of the 18th century. It has been called "the rarest of occult manuscripts"1 and the only surviving copy is owned by the library in Troyes, France.

Reader comment: Neil says,

It's worth pointing out that de Saint-Germain appears prominently in Neal Stephenson's lovely "Quicksilver".
Anne Stewart says,
If Saint-Germain sightings are of interest, it's also worth noting that he's all over Umberto Eco's "Foucault's Pendulum."
