«In the year of grace 1603, the Scottish follower Sethon Alexander, better known under the pseudonym of Cosmopolite, wrote in Latin a third treaty which completed his testamentary work  “Testamentum, De Transmutationibus Metallorum” – Testament or About the Transmutation of metals, which was enriched by his own hand of eleven emblems or “Clavicle.” According to his last wishes the two treaties, through his disciple Sendivogius were actually offered to the public: The philosopher’s stone in twelve treaties in 1604 and Dialogue of Mercury, the alchemist and nature, in 1607, in the same city of Cologne. About this third treaty and according to his last wishes, it was maintained in absolute secrecy and under the custody of the Filliis doctrinæ or Masters of the Hermetic Art, transmitting the most secret sacramentals procedures and practices to the deserving instructors. Four centuries have passed since then. Today, a new spirit in search of truth, combined with a sincere and perfectly disinterested aspiration, seems to emerge in the study of our alchemical art. Following the predicate of Cosmopolite, this quest seems to be an early signal which makes possible and even desirable the publication of the secret treaty. For this reason, the Treaty of Cosmopolite is revealed to the persistent researchers of our time. This book is preceded by a study of CHALYBE about the principal points of mineral Alchemy necessary for a proper understanding of this treaty essential for the alchemical literature which had not been printed yet.» [from the sidenotes]
