Isis Unveiled: A Master-Key to the Mysteries of Ancient and Modern Science and Theology, published in 1877, is a book of esoteric philosophy and Helena Petrovna Blavatsky's first major self-published major work text and a key doctrine in her self-founded Theosophical movement.
The work has often been criticized as a plagiarized occult work, with scholars noting how Blavatsky extensively copied from many sources popular among occultists at the time. Isis Unveiled is nevertheless also understood by modern scholars to be a milestone in the history of Western esotericism.
