First edition of this tract on Rosicrucianism which purports to have been written by Hugo de Alverda, and imaginary and very old Rosicrucian character.
The author, who wrote under the name of Irenaeus Agnostus, was Friederich Grick, perhaps one of the most peculiar participants in the catalogue of publications about the Brotherhood which came out in the first couple of decades of the century. Grick was a private tutor in Altdorf near Nuremberg. His publications conspicuously alternate between attacking and defending the sect, yet from his language his membership of the Brotherhood appears clear. Whilst in previous works his references to Rosicrucians ‘producing gold’ appeared to have simply an allegorical meaning of spiritual love, in the Fortalitium scientiae he associates the Brotherhood explicitly with alchemy by stating his belief in the Philosopher’s stone and mentioning experiments he had undertaken himself. Yet in other passages of the same work he offers nonsensical alchemical formulae, in clear mockery of alchemy. The text includes three letters of F.G. Menapius (i.e. J.V. Alberti) attacking the Roscicrucians to which this tract is a reply.

Collegium physico-chemicum experimentale, Oder Laboratorium Chymicum, In welchem Deutlich und gründlich Von den wahren Principiis in der Natur und denen gewürckten Dingen so wohl über als in der Erden, Als Vegetabilien, Animalien, Mineralien, Metallen, wie auch deren wahrhafften Generation Eigenschafften und Scheidung, Nebst der Transmutation und Verbesserung der Metallen gehandelt wird, Denen Liebhabern natürlicher Wissenschafften zum ungemeinen Nutzen nunmehro endlich Mit einem vollständigen Register und Vorrede herausgegeben Von Johann Caspar Engelleder.
the rare first edition of a famous chemical handbook, the most important work of the leading german chemist of the second half of the seventeenth century. Partington, devoting pp. 361-77 of vol. II to Kunckel, gives ‘a nearly complete bibliographical account with comment’ (Marie Boas Hall in DSB), with many references to the discoveries contained in this book, including as it does ‘an interesting account of the large laboratory (“gold house”) in Dresden, as big as a church, with furnaces and tall chimneys, of the old manuscripts, and of the harsh treatment of former alchemists who failed to achieve results ... Kunckel had great enthusiasm (es ist die Chymie das edelste Studium in der Welt), ample opportunities for experiment, a capacity for keen observation, great patience and stubborn application - in fact all the qualities which are found in a great chemist. He was a man of transparently honest character, and in such cases where his word is set against that of such men as Leibniz and Stahl, it may be accepted without hesitation’ (Partington).
