In The Mysteries of the Qabalah, Eliphas Levi links the Old and New Testaments of the Bible by comparing the qabalistic imagery and concepts inherent in both The Prophecy of Ezekiel and The Apocalypse of St. John. The first part is Levi's illuminating commentary on Ezekiel, and in the second part, Levi demonstrates that The Apocalypse of St. John is a symbolic resume of knowledge for initiates and a key to the high Qabalah.
