The present work contains a critical edition, translation, and study of the "Summa perfectionis" of Pseudo-Geber, the most influential of the many texts of medieval alchemy. The study addresses such questions as the author's identity, his corpuscular theory of matter, the influence of the "Summa," and its own sources.

The study addresses such questions as the author's identity, his corpuscular theory of matter, the influence of the Summa, and its own sources.

Summa Perfectionis, "The Height of Perfection," is attributed to Abu Musa Jabir ibn Hayyan (c. 721-815), who is most commonly known as Geber. This volume was selected by Hans Nintzel for inclusion in the R.A.M.S. Library due to numerous references to the text in major Alchemical works. Whatever the origin, this text has had a strong influence on the study of Alchemy for many centuries.

This is a new release of the original 1928 edition.

A classic, prize-winning novel about an epic migration and a lone woman haunted by the past in frontier Waipu. In the 1850s, a group of settlers established a community at Waipu in the northern part of New Zealand. They were led there by a stern preacher, Norman McLeod. The community had followed him from Scotland in 1817 to found a settlement in Nova Scotia, then subsequently to New Zealand via Australia. Their incredible journeys actually happened, and in this winner of the New Zealand Book Awards, Fiona Kidman breathes life and contemporary relevance into the facts by creating a remarkable fictional story of three women entangled in the migrations - Isabella, her daughter Annie and granddaughter Maria. McLeod's harsh leadership meant that anyone who ran counter to him had to live a life of secrets. The 'secrets' encapsulated the spirit of these women in their varied reactions to McLeod's strict edicts and connect the past to the present and future.

Since the Enlightenment, alchemy has been viewed as a sort of antiscience, disparaged by many historians as a form of lunacy that impeded the development of rational chemistry. But in Atoms and Alchemy, William R. Newman—a historian widely credited for reviving recent interest in alchemy—exposes the speciousness of these views and challenges widely held beliefs about the origins of the Scientific Revolution. Tracing the alchemical roots of Robert Boyle’s famous mechanical philosophy, Newman shows that alchemy contributed to the mechanization of nature, a movement that lay at the very heart of scientific discovery. Boyle and his predecessors—figures like the mysterious medieval Geber or the Lutheran professor Daniel Sennert—provided convincing experimental proof that matter is made up of enduring particles at the microlevel. At the same time, Newman argues that alchemists created the operational criterion of an “atomic” element as the last point of analysis, thereby contributing a key feature to the development of later chemistry. Atomsand Alchemy thus provokes a refreshing debate about the origins of modern science and will be welcomed—and deliberated—by all who are interested in the development of scientific theory and practice.
