La Très Sainte Trinosophie, The Most Holy Trinosophia, or The Most Holy Threefold Wisdom, is a French esoteric book, allegedly authored by Alessandro Cagliostro or the Count of St. Germain. Due to the dearth of evidence of authorship, however, there is significant doubt surrounding the subject. Dated to the late 18th century, the 96-page book is divided into twelve sections representing the twelve zodiacal signs. The veiled content is said to refer to an allegorical initiation, detailing many kabbalistic, alchemical and masonic mysteries. The original MS 2400 at the Library of Troyes is richly illustrated with numerous symbolical plates.

Giuseppe Balsamo, known by the alias Count Alessandro di Cagliostro, was an Italian occultist.
