Jābir Ibn Hayyān
Abū Mūsā Jābir ibn Ḥayyān (Arabic: , variously called al-Ṣūfī, al-Azdī, al-Kūfī, or al-Ṭūsī), died 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. Jabir's works contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride) from organic substances (such as plants, blood, and hair) by chemical means. His works also contain one of the earliest known versions of the sulfur-mercury theory of metals, a mineralogical theory that would rema ...

Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression traces back to 1615, when it first appeared in a book by Johannes Kepler as the la, annus aerae nostrae vulgaris (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the later 20th century, BCE and CE have become popular in academic and scientific publications because BCE and CE are religiously neutral terms. They are used by others who wish to be sen ...

Byzantine Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

History Of Pharmacy
The history of pharmacy as an independent science dates back to the first third of the 19th century. Before then, pharmacy evolved from antiquity as part of medicine. The history of pharmacy coincides well with the history of medicine, but it's important that there is a distinction between the two topics. Pharmaceuticals is one of the most-researched fields in the academic industry, but the history surrounding that particular topic is sparse compared to the impact its made world-wide. Before the advent of pharmacists, there existed apothecaries that worked alongside priests and physicians in regard to patient care. Prehistoric Pharmacy Paleopharmacological studies attest to the use of medicinal plants in pre-history. For example, herbs were discovered in the Shanidar Cave, and remains of the areca nut (''Areca catechu)'' in the Spirit Cave. Prehistoric man learned pharmaceutical techniques through instinct, by watching birds and beasts, and using cool water, leaves, dirt, or m ...

Medicine In The Medieval Islamic World
In the history of medicine, "Islamic medicine" is the science of medicine developed in the Middle East, and usually written in Arabic, the ''lingua franca'' of Islamic civilization. Islamic medicine adopted, systematized and developed the medical knowledge of classical antiquity, including the major traditions of Hippocrates, Galen and Dioscorides. During the post-classical era, Middle Eastern medicine was the most advanced in the world, integrating concepts of ancient Greek, Roman, Mesopotamian and Persian medicine as well as the ancient Indian tradition of Ayurveda, while making numerous advances and innovations. Islamic medicine, along with knowledge of classical medicine, was later adopted in the medieval medicine of Western Europe, after European physicians became familiar with Islamic medical authors during the Renaissance of the 12th century. Medieval Islamic physicians largely retained their authority until the rise of medicine as a part of the natural sciences, beg ...

Astrology In Medieval Islam
Some medieval Muslims took a keen interest in the study of astrology, despite the Islamic prohibitions (The Quran, points to the primary purpose of astrology as a means of providing physical guidance/navigation for an adherent, essentially considering its use in the capacity of horoscopes as forbidden.)partly because they considered the celestial bodies to be essential, partly because the dwellers of desert-regions often travelled at night, and relied upon knowledge of the constellations for guidance in their journeys.Wasim Aktar, ''Contributions of Ancient Arabian and Egyptian Scientists on Astronomy''Public Science & Reference, retrieved 19 August 2011. After the advent of Islam, the Muslims needed to determine the time of the prayers, the direction of the Kaaba, and the correct orientation of the mosque, all of which helped give a religious impetus to the study of astronomy and contributed towards the belief that the heavenly bodies were influential upon terrestrial affairs as ...

Astronomy In Medieval Islam
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowa ...

History Of Cosmology
Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe. The term ''cosmology'' was first used in English in 1656 in Thomas Blount's ''Glossographia'', and in 1731 taken up in Latin by German philosopher Christian Wolff, in ''Cosmologia Generalis''. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy it is concerned with the study of the chronology of the universe. Physical cosmology is the study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. It is investigated by scientists, such as astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time. Because of this shared scope with philosophy, theories i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth ( botany), the formation of igneous rocks ( geology), how atmospheric ozone is formed and how environmental pollutants are degraded ( ecology), the properties of the soil on the moon ( cosmochemistry), how medications work ( pharmacology), and how to collec ...

Alchemy
Alchemy (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.Principe, Lawrence M. The secrets of alchemy'. University of Chicago Press, 2012, pp. 9–14. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble metals" (particularly gold); the creation of an elixir of immortality; and the creation of panaceas able to cure any disease. The perfection of the human body and soul was thought to result from the alchemical ''magnum opus'' ("Great Work"). The concept of creating the philosophers' stone was variously connected with all of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Jaldaki
ʿIzz al-Dīn Aydamir al-Jildakī ( ar, عز الدين الجلدكي), also written al-Jaldakī (d. 1342 CE / 743 AH) was an Egyptian alchemist from the 14th century Mamluk Sultanate. Life Despite being one of the most important Islamic scholars of the 14th century, almost nothing is known about his early life. Al-Jildaki was probably born in Egypt into a family of Turkic Mamluk origin. In his writings he reveals that he spent seventeen years traveling through Iraq, Anatolia, Yemen, North Africa, and Syria Based on a speculative vocalization of his Nisba as "al-Jaldaki ", some 20th century writers like Henry Corbin suggested that he was originally from Jaldak, a town in Khorasan before emigrating to Egypt Nicholas G. Harris has criticized this theory noting that it was never mentioned in any pre-modern source before. Instead, he notes that all the biographical information known about him- like his Turkic name "Aydamir", places of residence and native language- would ma ...

Pseudo-Geber
Pseudo-Geber (or "Latin pseudo-Geber") is the presumed author or group of authors responsible for a corpus of pseudepigraphic alchemical writings dating to the late 13th and early 14th centuries. These writings were falsely attributed to Jabir ibn Hayyan (died 816, latinized as Geber), an early alchemist of the Islamic Golden Age. The most important work of the Latin pseudo-Geber corpus is the ("The Height of the Perfection of Mastery"), which was likely written slightly before 1310. Its actual author has been tentatively identified as Paul of Taranto. The work was influential in the domain of alchemy and metallurgy in late medieval Europe. The work contains experimental demonstrations of the corpuscular nature of matter that were still being used by seventeenth-century chemists such as Daniel Sennert, who in turn influenced Robert Boyle. The work is among the first to describe nitric acid, aqua regia, and aqua fortis. The existence of Jabir ibn Hayyan as a historical fig ...

Picatrix
''Picatrix'' is the Latin name used today for a 400-page book of magic and astrology originally written in Arabic under the title ''Ghāyat al-Ḥakīm'' ( ar, غاية الحكيم), which most scholars assume was originally written in the middle of the 11th century, though an argument for composition in the first half of the 10th century has been made. The Arabic title translates as ''The Aim of the Sage'' or ''The Goal of The Wise''. The Arabic work was translated into Spanish and then into Latin during the 13th century, at which time it got the Latin title ''Picatrix''. The book's title ''Picatrix'' is also sometimes used to refer to the book's author. ''Picatrix'' is a composite work that synthesizes older works on magic and astrology. One of the most influential interpretations suggests it is to be regarded as a "handbook of talismanic magic". Another researcher summarizes it as "the most thorough exposition of celestial magic in Arabic", indicating the sources for the wor ...
