Alchemy in the context of "Chlorine"

The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.

The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

Science in the ancient world encompasses the earliest history of science from the protoscience of prehistory and ancient history to late antiquity. In ancient times, culture and knowledge were passed through oral tradition. The development of writing further enabled the preservation of knowledge and culture, allowing information to spread accurately.

The earliest scientific traditions of the ancient world developed in the Ancient Near East, with Ancient Egypt and Babylonia in Mesopotamia. Later traditions of science during classical antiquity were advanced in ancient Persia, Greece, Rome, India, China, and Mesoamerica. Aside from alchemy and astrology that waned in importance during the Age of Enlightenment, civilizations of the ancient world laid the roots of modern sciences.

The history of science during the Age of Enlightenment traces developments in science and technology during the Age of Reason, when Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th- and 17th-century Scientific Revolution until roughly the 19th century, after the French Revolution (1789) and the Napoleonic era (1799–1815). The scientific revolution saw the creation of the first scientific societies, the rise of Copernicanism, and the displacement of Aristotelian natural philosophy and Galen's ancient medical doctrine. By the 18th century, scientific authority began to displace religious authority, and the disciplines of alchemy and astrology lost scientific credibility.

While the Enlightenment cannot be pigeonholed into a specific doctrine or set of dogmas, science came to play a leading role in Enlightenment discourse and thought. Many Enlightenment writers and thinkers had backgrounds in the sciences and associated scientific advancement with the overthrow of religion and traditional authority in favour of the development of free speech and thought. Broadly speaking, Enlightenment science greatly valued empiricism and rational thought, and was embedded with the Enlightenment ideal of advancement and progress. As with most Enlightenment views, the benefits of science were not seen universally; Jean-Jacques Rousseau criticized the sciences for distancing man from nature and not operating to make people happier.

A gnome (/noʊm/) is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, including those of modern fantasy literature. They are typically depicted as small humanoids who live underground. Gnome characteristics are reinterpreted to suit various storytellers and artists.

Paracelsus's gnome is recognized to have derived from the German miners' legend about Bergmännlein or dæmon metallicus, the "metallurgical or mineralogical demon", according to Georg Agricola (1530), also called virunculus montanos (literal Latinization of Bergmännlein = "mountain manikin") by Agriocola in a later work (1549), and described by other names such as cobeli (sing. cobelus; Latinization of German Kobel). Agricola recorded that according to the legends of that profession, these mining spirits acted as miming and laughing pranksters who sometimes threw pebbles at miners, but could also reward them by depositing a rich vein of silver ore.

The occult (from Latin occultus 'hidden, secret') is a category of esoteric or supernatural beliefs and practices which generally fall outside the scope of organized religion and science, encompassing phenomena involving a 'hidden' or 'secret' agency, such as magic and mysticism. It can also refer to paranormal ideas such as extra-sensory perception and parapsychology.

The term occult sciences was used in 16th-century Europe to refer to astrology, alchemy, and natural magic. The term occultism emerged in 19th-century France, among figures such as Antoine Court de Gébelin. It came to be associated with various French esoteric groups connected to Éliphas Lévi and Papus, and in 1875 was introduced into the English language by the esotericist Helena Blavatsky.

Western esotericism and the arts surveys documented intersections between Western esotericism—notably Hermeticism, Christian Kabbalah, Alchemy, and Astrology—and the visual arts, literature, and the performing arts from the late Middle Ages to the present. Scholarship highlights recurring vectors: Renaissance and early modern image–text programmes (emblems, alchemical series, Kabbalistic diagrams) that formalised "operative images"; encyclopedic displays and diagrams in early modern erudition; nineteenth-century Spirit photography and related "psychic" image technologies; fin de siècle milieux linking occult orders with salon culture; early twentieth-century abstraction tied to Theosophy/Anthroposophy; ritual poetics on stage and in experimental film; and later artist-authored Tarot and neo-alchemical process art.

Aby Warburg's reading of the Palazzo Schifanoia frescoes in Ferrara established a foundational model for interpreting astrological programs in Renaissance art, while Barbara Obrist documented the late-medieval shift toward serial illustration and diagrammatic representation in alchemical manuscripts. Early modern encyclopedic projects—epitomized by Athanasius Kircher—wove hieroglyphs, cosmology, and spectacular display into ambitious image-systems that influenced the period's visual culture. In parallel, historians of science and craft have emphasized how chymistry's "wider worlds" intersected with literature, theatre, and the visual arts. Classic studies have traced how esoteric metaphysics and "spiritual" aesthetics contributed to early abstraction (e.g., Wassily Kandinsky and Hilma af Klint), while recent scholarship reassesses the role of Spiritualism/Spiritism within abstract art and Surrealism's image-making and poetics.

Lynn Thorndike (24 July 1882, in Lynn, Massachusetts, US – 28 December 1965, New York City) was an American historian of medieval science and alchemy. He was the son of a clergyman, Edward R. Thorndike, and the younger brother of Ashley Horace Thorndike, an American educator and expert on William Shakespeare, and Edward Lee Thorndike, known for being the father of modern educational psychology.

In A Short History of Civilization (1926), Thorndike was the first historian to propose the term "early modern" to describe what is today recognized as the early modern period, about 1500–1800.
