Philosopher's stoneThe philosopher's stone, or more properly philosophers' stone (حجر الفلاسفة; lapis philosophorum), is a mythic alchemical substance capable of turning base metals such as mercury into gold (chrysopoeia, from the Greek χρυσός khrusos, "gold", and ποιεῖν poiēin, "to make") 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-after goal in alchemy.
HermeticismHermeticism or Hermetism is a philosophical and religious system based on the purported teachings of Hermes Trismegistus (a Hellenistic conflation of the Greek god Hermes and the Egyptian god Thoth). These teachings are contained in the various writings attributed to Hermes (the Hermetica), which were produced over a period spanning many centuries (300 BCE – 1200 CE) and may be very different in content and scope.
Western esotericismWestern esotericism, also known as esotericism, esoterism, and sometimes the Western mystery tradition, is a term scholars use to categorise a wide range of loosely related ideas and movements that developed within Western society. These ideas and currents are united since they are largely distinct both from orthodox Judeo-Christian religion and Enlightenment rationalism. It has influenced various forms of Western philosophy, mysticism, religion, pseudoscience, art, literature, and music.
AlchemyAlchemy (from Arabic: al-kīmiyā; from Ancient Greek: χυμεία, khumeía) 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. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.
Earth (classical element)Earth is one of the classical elements, in some systems being one of the four along with air, fire, and water. Earth is one of the four classical elements in ancient Greek philosophy and science. It was commonly associated with qualities of heaviness, matter and the terrestrial world. Due to the hero cults, and chthonic underworld deities, the element of earth is also associated with the sensual aspects of both life and death in later occultism. Empedocles of Acragas (c. 495 – c.
Giovanni Pico della MirandolaGiovanni Pico della Mirandola (ˈpiːkoʊ_ˌdɛlə_mɪˈrændələ,_-ˈrɑːn- , dʒoˈvanni ˈpiːko della miˈrandola; Johannes Picus de Mirandula; 24 February 1463 – 17 November 1494) was an Italian Renaissance nobleman and philosopher. He is famed for the events of 1486, when, at the age of 23, he proposed to defend 900 theses on religion, philosophy, natural philosophy, and magic against all comers, for which he wrote the Oration on the Dignity of Man, which has been called the "Manifesto of the Renaissance", and a key text of Renaissance humanism and of what has been called the "Hermetic Reformation".
ParacelsianismParacelsianism (also Paracelsism; German: Paracelsismus) was an early modern medical movement based on the theories and therapies of Paracelsus. It developed in the second half of the 16th century, during the decades following Paracelsus' death in 1541, and it flourished during the first half of the 17th century, representing one of the most comprehensive alternatives to learned medicine, the traditional system of therapeutics derived from Galenic physiology.
HumorismHumorism, the humoral theory, or humoralism, was a system of medicine detailing a supposed makeup and workings of the human body, adopted by Ancient Greek and Roman physicians and philosophers. Humorism began to fall out of favor in the 17th century and it was definitively disproved in the 1850s with the advent of germ theory, which was able to show that many diseases previously thought to be humoral were in fact caused by microbes.
Early modern periodThe early modern period of modern history spans the period after the Late Middle Ages of the post-classical era (1400–1500) to the beginning of the Age of Revolutions (1800). Although the chronological limits of this period are open to debate, the timeframe is variously demarcated by historians as beginning with the fall of Constantinople in 1453, the Renaissance period in Europe and Timurid Central Asia, the end of the Crusades, the Age of Discovery (especially the voyages of Christopher Columbus beginning in 1492 but also Vasco da Gama's discovery of the sea route to India in 1498), and ending around the French Revolution in 1789, or Napoleon's rise to power.
BloodlettingBloodletting (or blood-letting) is the withdrawal of blood from a patient to prevent or cure illness and disease. Bloodletting, whether by a physician or by leeches, was based on an ancient system of medicine in which blood and other bodily fluids were regarded as "humours" that had to remain in proper balance to maintain health. It is claimed to have been the most common medical practice performed by surgeons from antiquity until the late 19th century, a span of over 2,000 years.
