"Dubbed ‘the most prominent alchemical physician in Germany since Paracelsus,’ Michael Maier was Royal Physician and Count Palatine to Holy Roman Emperor Rudolf II. A doctor, diplomat and alchemist, Maier spent much of his life in a poignant, fruitless quest for the elusive Rosicrucian Brotherhood; visionaries and intellectuals whose Manifestos proclaiming a “universal reformation of mankind” had caused an immense impact on European culture in the wake of decades of religious warfare. 
Maier produced a variety of works synthesising his interests in healing, alchemy, and esoteric philosophy. His Atalanta fugiens (1617) was designed to simultaneously stimulate the senses, the intellect, and the spirit through engagement with the emblems, music, and text, to lead the reader on a path to self-initiation through the secrets of alchemical knowledge. In this richly illustrated book, Sasha Chaitow traces this path through the structure and content of the Atalanta fugiens together with a number of Maier’s other works. She explores the coded mythical references in the images and provides evidence that the emblems need to be rearranged to decode Maier’s full message."

"In Chinese alchemy, elixir poisoning refers to the toxic effects of elixirs of immortality that contain metals and minerals such as mercury and arsenic. The official Twenty-Four Histories record numerous Chinese emperors, nobles, and Officials who ironically died from taking elixirs in order to prolong their lifespans. The first emperor to die from a poisoning elixir was probably Qin Shi Huang (d. 210 BCE) and the last was Yongzheng (d. 1735). Despite common knowledge that immortality potions could be deadly, fangshi and Daoist alchemists continued the elixir-making practice for two millennia."

"I have intended for sometime to write a little piece on the stages of alchemical work.There are several books on alchemy, but I’m afraid not very many talk in a clear manner of the alchemical process itself. Surely, throughout the centuries alchemicaltechniques underwent a natural evolution, and matters are complicated by the personaltouch each alchemist set on the process. However, it appears that the Western alchemical tradition maintained a consistency of four phases expressed in colors."

"“MS. 446" WAS PRODUCED IN FRANCE, IN THE LATE 15TH CENTURY AND IS A RICH EXAMPLE OF AN ALCHEMICAL TREATISE. IT IS, HOWEVER, DEVOID OF MOST OF THE CRYPTIC ALCHEMICAL PHRASES THAT ARE SO ENIGMATIC TO US IN THE PRESENT DAY. IT CENTERS, RATHER, ON THE TECHNICAL POSSIBILITIES OF THE ART. AMPLY ILLUSTRATED, WITH 56 COLOR DRAWINGS, IT DETAILS 20 CHEMICAL PROCEDURES AND PROCESSES. THE MAIN TEXT IS FOLLOWED BY SEVEN FOLIOS OF FULL-PAGE ALCHEMICAL DRAWINGS, SEVEN FOLIOS CONTAINING AN ALCHEMICAL SYNTHESIS, AND THREE FOLIOS OF PRACTICAL RECIPES."

"This paper manuscript, produced around 1700, mentions in its title Emperor Leopold (I, reigned 1658-1705). The identity of Giovanni Baptista Coene from Passau, named as author, remains obscure; no further information is available about him. — The names of metals and other materials that Coene used in experiments are not written out in the text, but are represented by alchemic symbols (planetary signs, etc.). Because these occur in large numbers, the text is not easily readable or understandable. Further evidence that the manuscript is rooted in alchemy comes from the fact that Coene refers to Paracelsus (1493/94-1541)."

Thanks to a generous donation from Da Vinci Code author Dan Brown, Amsterdam’s Ritman Library—a sizable collection of pre-1900 books on alchemy, astrology, magic, and other occult subjects—has been digitizing thousands of its rare texts under a digital education project cheekily called “Hermetically Open.”

"This study concerns an English-language alchemical work called The Mirror of Alchemy (MoA). I examine manuscript copies of MoA from the 15th to 17th centuries as well as a printed edition from 1597. The main aim of my study is to edit a previously unstudied manuscript version of MoA, making this work accessible for future research and contributing to developing editorial methods for early scientific texts. A central aim is to place MoA in its textual and historical contexts to clarify the edited text to readers. I employ theory and methods from the fields of scholarly editing and textual scholarship, and integrate the discussion of manuscript and printed witnesses."
