The Secret Teachings of All Ages is perhaps the most comprehensive and complete esoteric encyclopedia ever written. The sheer scope and ambition of this book are stunning. In this book Manly P. Hall has successfully distilled the essence of more arcane subjects than one would think possible. He covers Rosicrucianism and other secret societies, alchemy, cryptology, Kabbalah, Tarot, pyramids, the Zodiac, Pythagorean philosophy, Masonry, gemology, Nicholas Flammel, the identity of William Shakespeare, The Life and Teachings of Thoth Hermes Trismegistus, The Qabbalah, The Hiramic Legend, The Tree of the Sephiroth, and Mystic Christianity. There are more than 200 illustrations included here (and in the trade paperback edition) many of which have been omitted from other publisher's editions of this book. This is essential reading for anyone wishing to explore esoteric knowledge.

In 'Ala' al-Dawla al-Simnani between Spiritual Authority and Political Power: A Persian Lord and Intellectual in the Heart of the Ilkhanate, Giovanni Maria Martini investigates the personality of a major figure in the socio-political and cultural landscape of Mongol Iran. In pursuing this objective, the author follows parallel paths: Chapter 1 provides the most updated reconstruction of Simnani's (d. 736/1336) biography, which, thanks to its unique features, emerges as a cross-section of Iranian society and as a microhistory of the complex relationships between a Sufi master, Persian elites and Mongol rulers during the Ilkhanid period; Chapter 2 contains a study on the phenomenon of Arabic-Persian diglossia in Simnani's written work, arguing for its socio-religious function; in Chapters 3 to 6 the critical editions of two important, interrelated treatises by Simnani are presented; finally, Chapter 7 offers the first full-length annotated translation of a long work by Simnani ever to appear in a Western language.
