Biographical preface by A. E. Waite. "To the illustrious, venerable, saintly, and blessed men, adepts of the true philosophy, lovers of virtue, lords of fortune, despisers of the world, whose life is holiness in holiness, knowledge in knowledge, and whose work consists in the relieving of the sick and poor." This illuminating work reveals the secrets of the Spagyric Art; the Grand Magisterium, the true and Universal Medicine, the Tinctures which transmute metals, and other deep mysteries that make part of the Sacramentum Regis.
