- Twilit Grotto -- Esoteric Archives -Heinrich Cornelius Agrippa: Of Occult Philosophy, Book I. (part 1) "In 1801 Agrippa's text, in a slightly abridged form, was shamelessly plagiarized and published as his own work by Frances Barrett (The magus, or Celestial intelligencer, London 1801). This work can still be found in print. The latter was in turn plagiarized and published as his own work by L.W. de Laurence (The Great Book of Magical Art, Hindoo Magic & Indian Occultism, (Chicago, 1915)!"
- Amazon Three Books of Occult Philosophy (Llewellyn's Sourcebook) Paperback- Editorial Reviews From the Publisher "Barrett's The Magus is a direct plagiarism of a part of this book. The Hermetic Order of the Golden Dawn's systems of the Kabbalah, geomancy, elements, and seals and squares of the planets are all taken, in a large measure, from Agrippa—but for 500 years, Three Books of Occult Philosophy was almost impossible to find."
