Astrology was an integral part of university teaching in the Middle Ages. The discipline of astronomia comprehended not only the calculation of planetary orbits, but also the casting of horoscopes, the calculation of houses and aspects, the character of the various planets, and the like. Although the astronomical and astrological parts were separate and had their own textbooks, both domains were taught in the same body of education. However, starting in the seventeenth-century, universities gradually no longer considered the teaching of astrological techniques as their task. Astronomy developed further without any link to astrological pursuits.

This fascinating book from 1676 re translated into English written by one of the most obscure alchemists Edward Kelly stands as one of the rarest and most enigmatic documents within the Western Hermetic corpus, a synthesis of late Renaissance alchemy, Platonic cosmology, early modern experimental chemistry, and esoteric theology. Purportedly composed by Edward Kelly (1555–1597), the famed associate of Dr. John Dee, it reflects the intellectual crosscurrents of the Elizabethan period—when religion, magic, and nascent science were indistinguishable modes of knowing the divine architecture of the universe. Kelly’s treatise fuses Biblical typology with alchemical symbolism, casting the transmutation of metals as an analog of the spiritual regeneration of Adam’s fallen seed.🔑 The “Philosopher’s Stone” becomes a hieroglyph for the restoration of Edenic wholeness, mirroring Pauline doctrines of incorruption (1 Corinthians 15:42–54) and the promise of divine perfection. The “Earth of the Sages,” “Virgin’s Milk,” and “Hermaphroditic Water” parallel mystical descriptions of the Virgin Birth and the Holy Spirit’s generative medium, aligning alchemical conceptions of prima materia with the Genesis account of creation “from the dust of the ground.”🔑 From a cosmological perspective, Kelly’s text unites the four Aristotelian elements (Earth, Air, Fire, Water) with the Biblical fourfold rivers of Paradise (Genesis 2:10–14) and the Zoroastrian four Lights described in Persian theosophy, thus situating the work within an ancient Indo-Mediterranean lineage of sacred cosmography. The chapter on the “First Matter of Minerals” resonates with Egyptian and Chaldean metaphysics—particularly the notion of a divine ferment (Ka or Ruach) animating inert substance. In this way, the book bridges the Egyptian Hermetica, Greek Neoplatonism, and Hebrew Kabbalah, revealing the alchemist’s furnace as both a laboratory of nature and a temple of divine reconciliation. 🔑 From a philosophical standpoint, Kelly echoes the Platonic axiom that like is known by like: to purify metals is to purify the soul. This moral-alchemical parallelism recalls the Orphic and Pythagorean initiatory traditions, while also prefiguring the moral chemistry of later figures like Paracelsus and Jacob Boehme, who envisioned the cosmos as a spiritual crucible. The Azoth, or universal solvent, is described as both the vital spirit of the world and the Logos incarnate—an interpretation that finds resonance in the Gospel of John, the Sefer Yetzirah, and the Corpus Hermeticum alike.🔑 In scientific and proto-chemical terms, the treatise preserves a rare transitional vocabulary. It straddles the empirical curiosity of Roger Bacon, George Ripley, and Arnold de Villanova with the emergent rationalism of Boyle’s corpuscular theory. The numerous references to sulphur, mercury, and salt prefigure the Tria Prima of Paracelsian chemistry—anticipating the separation of chemical analysis from spiritual allegory. Yet Kelly refuses a purely material reading: his elements are both tangible and metaphysical, aligning with the later Swedenborgian idea of correspondences between heaven and the natural world. 🔑 CONTENTS WITH IN DEPTH SUMMARIES FOR EACH CHAPTER + BELOW THAT IF FULL RETYPED INDEX 🔑 Biographical Preface .... ix The Stone of the Philosophers ... 1 Certain Fragments selected from the Letters of Edward Kelly .... 51 The Humid Way, or a Discourse upon the Vegetable Menstruum of Saturn 55 The Theatre of Terrestrial Astronomy ....... 111 Index ....... 149 🔑 DEEP SUMMARIES for each above chapter 🔑 Biographical Preface (pp. ix–xviii) This preface offers a rare scholarly look into the life of Edward Kelly (1555–1597) — the enigmatic alchemist and companion of Dr. John Dee. It explores Kelly’s rise from a reputed “necromancer” to an esoteric adept employed by Emperor Rudolf II in Prague. The Preface contextualizes Kelly’s work amid the Renaissance revival of Hermetic and Paracelsian thought, emphasizing his attempts to achieve the Philosopher’s Stone through spiritual revelation as well as chemical art. It recounts his imprisonment, mystical “shew-stone” visions with Dee, and his controversial claims to angelic dictation, reflecting on whether his “transmutations” were literal or allegorical. The editor also situates Kelly’s writings within the lineage of alchemical mystics such as Arnold of Villanova, Bernard of Treviso, and Raymond Lully, portraying him as a transitional figure between medieval and Rosicrucian alchemy. Philosophically, this section argues that Kelly’s alchemy was anagogical — not merely metallic but spiritual — aiming to transmute the base metals of the soul into divine illumination. 🔑 The Stone of the Philosophers (pp. 1–50) Kelly’s primary treatise, De Lapide Philosophorum, is both cosmological and practical. It describes the genesis of the First Matter, the “chaos” containing all elements before separation by the divine Word. He teaches that the Stone, or Magistery, arises from the union of Sulphur (active, male, solar) and Mercury (passive, female, lunar) under the mediation of Salt, reflecting a trinitarian cosmology rooted in Hermetic principles. He elaborates the “Way of the Sages”, defining the processes of putrefaction, calcination, sublimation, and conjunction, which mirror spiritual death and resurrection. His vision is that Nature herself performs alchemy continually, and that man, made in God’s image, imitates this divine art by purifying matter and soul. Kelly cites classical authorities such as Hermes Trismegistus, Democritus, Anaxagoras, and Aristotle, integrating them with Christian theology. Notably, he insists that the Stone is found within Mercury, the “seed of all metals,” and that the alchemist must find “the Sun and Moon within one substance.” The treatise culminates in a mystical exegesis of the Emerald Tablet, describing how the macrocosm and microcosm are joined through the Fire of the Sages — spiritual illumination through divine wisdom. 🔑 Certain Fragments selected from the Letters of Edward Kelly (pp. 51–54) This section gathers scattered epistolary fragments where Kelly writes to unnamed patrons and adepts concerning his philosophic discoveries. The tone is urgent and mystical — part confession, part instruction. He warns against “the greedy and profane” who would force Nature’s secrets through avarice. His letters emphasize the need for inner purification before external success, revealing that “the gold of the Wise is the gold of the Spirit.” References appear to the Black Raven, Green Lion, and Hermaphroditic Water, each a coded symbol for alchemical stages: nigredo (death), viriditas (renewal), and coniunctio (union). Kelly here stands as a moral philosopher of alchemy, asserting that the true laboratory is “the heart made clean through fire.” 🔑 The Humid Way, or a Discourse upon the Vegetable Menstruum of Saturn (pp. 55–110) Perhaps Kelly’s most technical text, this discourse presents the “Humid Way” — a method distinct from the “Dry Way” of the metallic philosophers. It centers on the Vegetable Menstruum, a mercurial solvent derived from the spirit of Saturn (Lead), used to dissolve metals and awaken their hidden vitality. Kelly here demonstrates familiarity with Paracelsian spagyrics — describing how the vegetable kingdom mirrors the metallic through menstruum, fermentation, and circulation. He analogizes the process to cosmic regeneration: Saturn’s heaviness conceals the seed of light, which the alchemist must liberate by the gentle fire of nature. This “humid path” is less violent and more organic — a slow alchemy of growth, akin to spiritual temperance. The discourse is filled with cosmological symbolism: the Menstrual Water of the Moon, Virgin’s Milk, and Peacock’s Tail denote stages of purification and illumination. In its metaphysical dimension, the treatise unites alchemy with botany, astrology, and theology, suggesting that all creation moves toward one goal — the perfection of light in matter. 🔑 The Theatre of Terrestrial Astronomy (pp. 111–148) A poetic and visionary synthesis of alchemy, cosmology, and astro-theology. Kelly compares the alchemist’s laboratory to the heavens themselves — the furnaces are planets, the elements are constellations, and the work of transformation mirrors the order of the cosmos. He outlines the Seven Planets and their correspondences to metals and virtues: • ☉ Sun — Gold — Illumination • ☽ Moon — Silver — Purity • ♂ Mars — Iron — Courage • ♃ Jupiter — Tin — Benevolence • ♀ Venus — Copper — Love • ☿ Mercury — Quicksilver — Wisdom • ♄ Saturn — Lead — Humility The “Theatre” thus becomes a symbolic map of the universe where spiritual alchemy is the study of divine astronomy within oneself — as above, so below. 🔑 TAGS 🔑 Alchemy, transmutation, prima materia, philosopher’s stone, hermetic philosophy, biblical symbolism, esoteric cosmology, Adamic dust, Edenic restoration, divine fire, sacred chemistry ...

Astrum et Herba: A Historical and Philosophical Report on Astrological Herbalism, 2025

Astrological herbalism, in its deepest essence, is not simply a therapeutic practice, but a complete cosmological system, a Weltanschauung that postulates a resonant and sympathetic universe. It is a paradigm in which the celestial macrocosm-the movements, natures and influences of the planets and stars-is reflected and acts on the terrestrial microcosm, manifesting itself in the plant kingdom and in the human body. This discipline is based on a fundamental principle: the universe is a single living organism, unified and interconnected, whose parts communicate through a network of occult or hidden correspondences. Understanding these correspondences means deciphering God's signature on creation and acquiring the ability to restore harmony, and therefore health, in the human being.

Sciences of Antiquity is a series designed to cover the subject matter of what we call science. The volumes discuss how the ancients saw, interpreted and handled the natural world, from the elements to the most complex of living things. Their discussions on these matters formed a resource for those who later worked on the same topics, including scientists. The intention of this series is to show what it was in the aims, expectations, problems and circumstances of the ancient writers that formed the nature of what they wrote. A consequent purpose is to provide historians with an understanding of the materials out of which later writers, rather than passively receiving and transmitting ancient 'ideas', constructed their own world view.
