Book of Dzyan
According to L. Sprague de Camp, this is a fictional book concocted by Helena Petrovna Blavatsky, founder of Theolophy, in her 'Secret Doctrine' (1888). This treatise, a mass of fakery and plagarism, consists mainly of quotations from the "Dzyan" (pronounced something like "John") interspersed with commentaries and diatribes. Although Mme. Blavatsky said that the "Dzyan" was originally written in Atlantis in the lost Senzar language, it is actually paraphrased without credit from an English translation of the ancient Sanskrit "Rig-Veda."
