This article investigates several discussions of “chemistry,” understood as an analysts’ category referring to theories and practices dealing with the structure and transformation of matter. By reading these texts (a treatise defending kīmiyāʾ by al-Fārābī, the famous passage from Ibn Sīnā’s Shifāʾ on transmutation, Ibn Taymiyyah’s fatwā…[Read more]

The term “alchemy,” born out of early modern professional polemics among chemists, is problematic as a historical category. The present article shifts away from asking what pre-modern alchemy “really” was, to asking how medieval scholars writing in Greek and Arabic thought about the practice of treating and combining naturally occurring substan…[Read more]

The early modern use of vegetal terms to explain the origin and growth of ores was widespread in mining industry, alchemy, and natural philosophy. In the writings of authors from many different backgrounds, mineral veins were often described as ‘trees’ which moved upwards, bore fruits, and underwent a life cycle. Accordingly, the existence in ore…[Read more]

Freemasonry has traditionally been seen as a key influence in the rise of the Bourgeoisie, since it allegedly subdued social boundaries and behavioural norms of the Ancien Régime. This paper, however, argues that the masonic lodges at least in the smaller German court towns, adopted various elements of court society – organizational structures, my…[Read more]

This article examines a little-known and unstudied alchemical treatise, The Epistle on Alchemy (al-Risāla fī l-ṣināʿa) attributed to Aristotle, purportedly translated from Syriac into Arabic by the Nestorian bishop ʿAbdīshōʿ bar Brīkhā (d. 1318). In particular, I investigate the Epistle’s discourse on the concealment and revelation of alchemical…[Read more]

The period between c. 1870 and c. 1930 marks the height of the European expansion respectively the age of ‘high imperialism’. It also marks the first wave of decolonization. The tid…[Read more]

How did (Western) European freemasonries on a transnational level came to terms with the idea of a closer union of the European peoples? Concepts of “Europe” and “Europeanness” were the background music of the formation of masonic pan-European networks, building on transnational encounters either by individual freemasons (in the Universala Framaso…[Read more]

The period of masonic internationalism in the last third of the 19th and first third of the 20th centuries saw the most visible – and controversial – attempts to organisationally model the “cosmopolitan imperative” of freemasonry. The various freemasonries in Europe saw themselves as links in a world-spanning “chain of brothers” forged by the…[Read more]

New evidence on scholarly patronage under the Roman empire can be garnered by analyzing the descriptions of learned magoi in several texts from the second to the fourth century CE. Since a common use of the term magos connoted flatterer-like figures (kolakes), it is likely that the figures of “learned sorcerers” found in texts such as Luc…[Read more]

Freedom of or from religion. Freemasonry as an international testing ground for fundamental societal issues (c. 1850–1930)
In masonic internationalism, key framework parameters of masonic activity were negotiated. They concerned the fundamental societal issue of how religious freedom (freedom to practise religion) and liberty of conscience (…[Read more]

Freemasons often referred to an ideal of “humanité” (Humanität, umanità, humanity) in order to bridge all differences separating mankind. In doing so, they rendered these differences all the more visible, especially in the international arenas. This was definitely the case when freemasons tried to deduce from this ideal “universal” standards…[Read more]

The chair of chymiatria created at the University of Marburg was among the earliest academic initiatives aiming to integrate chymistry into the medical curriculum. If its practical applications in pharmacy and its relationship with patronage have been examined by historians, the theoretical part of the chymiatria programme still remains to be…[Read more]

Pero con la aparición de Napoleón en la escena europea, Inglaterra impuso el “blo…[Read more]

Hylomorphism is a recent term in the history of philosophy and the sciences. What was used from Antiquity to the early modern period was the terminological couple “matter” and “form.” According to the Aristotelian physics, matter and form are indissociable principles which constitute the elements and preside over the generation and destruc…[Read more]

The genesis and growth of minerals, as well as the existence in ore veins of such organic features as ‘seeds’, ‘matrices’, and ‘nourishment’, remained central and recurrent issues for natural philosophers, technicians, alchemists and practitioners throughout early modern Europe. By providing an overview of the main themes, voices, and concurrent…[Read more]
