The Earl of St. Germain is an enigmatic figure in history who lived in France in the 18th century. His year of birth varies between 1691 and 1712, his death on February 27, 1784.

St. Germain has been described as an alchemist, courtier, adventurer, inventor, pianist, violinist, and hobbyist composer, but is best known as a recurring figure in stories inherent in the occult, particularly those related to Theosophy and the White Eagle Lodge, where he is also known as Master Rakoczi or Master Saint Germain or Sanctus Hermanus and also as one of the Masters of Ancient Wisdom. They accredit him almost divine powers and longevity.

St. Germain remains with us in one magical way or another. Alchemy has come to mean the transformation of consciousness set in "time" to its natural state of light, a process that is going on today. The adventures of St. Germain were as real or illusionary as one perceives them to be, for all of reality is nothing more than a consciousness hologram set in the illusion of time for experience.

One of the revealing books of his life is La Très Sainte Trinosophie and the untitled Triangular Manuscript.
