Ortolanus (fl. 1300), also known as Hortulanus, was a medieval alchemist. Little information exists about his life and identity. He is best known for his influential commentary on The Emerald Tablet entitled Liber super textum Hermetis. It was composed before 1325, and the original work has two sections.
The first is entitled Spiritus quinte essentie et in quo elemento habitat. It is dedicated to making a prodigious substance, the quintessence, from a mysterious material called argento vivo, which happens to be wine. Ortholan is the first author to relate alcohol and quintessence, half a century before Jean de Roquetaillade. [1] According to his view, the quintessence would have a universal presence, but is best obtained of some substances; ideally the wine.
The second part is a theoretical text. It is written as a comment to the Emerald Tablet attributed to Hermes. Its theme revolves around the primordial heat, praised by Hermes as a universal substrate that gives dynamism to the whole cosmos. Ortolanus believes alcohol or quintessence is the hidden primordial heat in all material things. This second part was published in the alchemical compilation In hoc volumine de alchemia continentur hæc (1541). It was printed again in 1545. A 1560 edition appeared under the name Compendium alchimiae and was attributed to Johannes de Garlandia (philologist). Another edition followed in 1571. [2] With this widespread publishing, the second section became very popular among alchemists of the Early modern period. The first part, which was never published, was forgotten and no one related Ortolanus to the development of the concept of quintaessencia.
The true identity of Ortolanus is unknown. His works have been falsely attributed to Johannes de Garlandia (philologist) (fl. 1205–1255), and more probably to Jakob Ortlein of Nördlingen (fl. 1275–1325), who may have been a Dominican friar. [3] He has also been given the names Martin Ortolan or Lortholain in later sources.
The preface of his famous commentary gives a hint to his identity: "I Hortulanus, so called from the Gardens bordering upon the sea coast, wrapped in a Iacobin skinne, unworthy to be called a Disciple of Philosophie...".
There is a later commentary by an alchemist called John Bumbles or Dombelay: Practica vera alchemica. It was completed in 1386 and dedicated to Kuno II von Falkenstein. This work claims to be based on a practice done by the author himself or someone else in 1358. [5]
Alchemy is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practiced in China, India, the Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Greco-Roman Egypt during the first few centuries AD.
Abū Mūsā Jābir ibn Ḥayyān, died c. 806−816, is the purported author of an enormous number and variety of works in Arabic, often called the Jabirian corpus. The works that survive today mainly deal with alchemy and chemistry, magic, and Shi'ite religious philosophy. However, the original scope of the corpus was vast and diverse, covering a wide range of topics ranging from cosmology, astronomy and astrology, over medicine, pharmacology, zoology and botany, to metaphysics, logic, and grammar.
Hermes Trismegistus is a legendary Hellenistic figure that originated as a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. He is the purported author of the Hermetica, a widely diverse series of ancient and medieval pseudepigraphical texts that lay the basis of various philosophical systems known as Hermeticism.
The philosopher's stone, more properly philosophers' stone or stone of the philosophers, is a mythic alchemical substance capable of turning base metals such as mercury into gold or silver. It is also called the elixir of life, useful for rejuvenation and for achieving immortality; for many centuries, it was the most sought goal in alchemy. The philosophers' stone was the central symbol of the mystical terminology of alchemy, symbolizing perfection at its finest, enlightenment, and heavenly bliss. Efforts to discover the philosopher's stone were known as the Magnum Opus.
Hermeticism or Hermetism, the practice of which is sometimes called Hermetics, is a label used to designate a philosophical system that is primarily based on the purported teachings of Hermes Trismegistus. These teachings are contained in the various writings attributed to Hermes, which were produced over a period spanning many centuries, and may be very different in content and scope.
The Hermetica are texts attributed to the legendary Hellenistic figure Hermes Trismegistus, a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. These texts may vary widely in content and purpose, but are usually subdivided into two main categories, the "technical" and "religio-philosophical" Hermetica.
The Corpus Hermeticum is a collection of 17 Koine Greek pseudepigraphical writings whose authorship is traditionally attributed to the legendary Hellenistic figure Hermes Trismegistus, a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. The treatises were originally written between c. 100 and c. 300 CE, but the collection as known today was first compiled by Medieval Byzantine editors, and translated into Latin in the 15th century by the Italian humanist scholars Marsilio Ficino (1433–1499) and Lodovico Lazzarelli (1447–1500).
Ars antiqua, also called ars veterum or ars vetus, is a term used by modern scholars to refer to the Medieval music of Europe during the High Middle Ages, between approximately 1170 and 1310. This covers the period of the Notre-Dame school of polyphony, and the subsequent years which saw the early development of the motet, a highly varied choral musical composition. Usually the term ars antiqua is restricted to sacred (church) or polyphonic music, excluding the secular (non-religious) monophonic songs of the troubadours, and trouvères. However, sometimes the term ars antiqua is used more loosely to mean all European music of the thirteenth century, and from slightly before. The term ars antiqua is used in opposition to ars nova, which refers to the period of musical activity between approximately 1310 and 1375.
The Emerald Tablet, also known as the Smaragdine Tablet or the Tabula Smaragdina, is a compact and cryptic Hermetic text. It was highly regarded by Islamic and European alchemists as the foundation of their art. Though attributed to the legendary Hellenistic figure Hermes Trismegistus, the text of the Emerald Tablet first appears in a number of early medieval Arabic sources, the oldest of which dates to the late eighth or early ninth century. It was translated into Latin several times in the twelfth and thirteenth centuries. Numerous interpretations and commentaries followed.
John of Seville was one of the main translators from Arabic into Castilian in partnership with Dominicus Gundissalinus during the early days of the Toledo School of Translators. John of Seville translated a litany of Arabic astrological works, and is also credited with the production of several original works in Latin.
Franco of Cologne was a German music theorist and possibly a composer. He was one of the most influential theorists of the Late Middle Ages, and was the first to propose an idea which was to transform musical notation permanently: that the duration of any note should be determined by its appearance on the page, and not from context alone. The result was Franconian notation, described most famously in his Ars cantus mensurabilis.
In medieval music, the rhythmic modes were set patterns of long and short durations. The value of each note is not determined by the form of the written note, but rather by its position within a group of notes written as a single figure called a "ligature", and by the position of the ligature relative to other ligatures. Modal notation was developed by the composers of the Notre Dame school from 1170 to 1250, replacing the even and unmeasured rhythm of early polyphony and plainchant with patterns based on the metric feet of classical poetry, and was the first step towards the development of modern mensural notation. The rhythmic modes of Notre Dame Polyphony were the first coherent system of rhythmic notation developed in Western music since antiquity.
The Aurora consurgens is an alchemical treatise of the 15th century famous for the rich illuminations that accompany it in some manuscripts. While in the last century, the text has been more commonly referred to as "Pseudo-Aquinas", there are as well arguments in favour of Thomas Aquinas, to whom it has originally been attributed in some manuscripts. The translated title from Latin into English is "Rising dawn."
Johannes de Garlandia or John of Garland was a medieval grammarian and university teacher. His dates of birth and death are unknown, but he probably lived from about 1190 to about 1270.
Ludovico Lazzarelli was an Italian poet, philosopher, courtier, hermeticist and (likely) magician and diviner of the early Renaissance.
John Dastin (c.1293-c.1386) was an English alchemist of the fourteenth century. Little is known of his life beyond the texts which are attributed to him. Dastin is known for correspondence with Pope John XXII and Cardinal Napoleone Orsini in defense of alchemical practice, dated to 1320.
Muḥammad ibn Umayl al-Tamīmī, known in Latin as Senior Zadith, was an Egyptian alchemist who lived from c. 900 to c. 960 AD.
Johannes Alanus was an English composer. He wrote the motet Sub arturo plebs/Fons citharizancium/In omnem terram. Also attributed to him are the songs "Min frow, min frow" and "Min herze wil all zit frowen pflegen", both lieds, and "S'en vos por moy pitié ne truis", a virelai. O amicus/Precursoris, attributed simply to "Johannes", may be the work of the same composer.
The Mirror of Alchimy is a short alchemical manual, known in Latin as Speculum Alchemiae. Translated in 1597, it was only the second alchemical text printed in the English language. Long ascribed to Roger Bacon (1214-1294), the work is more likely the product of an anonymous author who wrote between the thirteenth and the fifteenth centuries.
Giovanni Mercurio da Correggio was an Italian itinerant preacher, Hermeticist, and alchemist. Due to his bizarre appearance in Rome on Palm Sunday 1484 he has been believed by some scholars to have not actually existed, but this has been contested with other reports that corroborate his eccentricities. His most notable follower was Lodovico Lazzarelli, an Italian humanist poet and alchemist, who writes his accounts of da Correggio in his Epistola Enoch.
