Bernard Trevisan
Bernard Trevisan (''Bernard of Treviso'', ''Bernardus Trevisanus'') was a fictional Italian alchemist who lived from 1406-1490. His biography has been composed by editors and commentators of alchemical texts from the 16th century. It is said that he was born into a noble family in Padua and spent his entire life spending his family fortune in search of the Philosopher's stone. The mythical character emerged by a confusion with the alchemist called Bernard of Trier. A recent study founded a chronicle of his death in 1387. He has been identified with Eberhard I von der Mark (1305-1387), a law graduate and clergyman, who became chorbishop of Cologne. He resigned his positions in the Church to marry in 1346 with Maria de Looz-Agimont (ca.1336-1410), whose titles and territories counties were key points in feudal disputes involving Von der Marck family. From 1366 he was closely related to Kuno II von Falkenstein (ca.1320-1388), archbishop of Trier. Biography The fictional Bernard Tr ...

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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jabir Ibn Hayyan
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 remain d ...

Charles VIII Of France
Charles VIII, called the Affable (french: l'Affable; 30 June 1470 – 7 April 1498), was King of France from 1483 to his death in 1498. He succeeded his father Louis XI at the age of 13.Paul Murray Kendall, ''Louis XI: The Universal Spider'' (New York: W. W. Norton & Company, 1971), pp. 373–374. His elder sister Anne acted as regent jointly with her husband Peter II, Duke of BourbonStella Fletcher, ''The Longman Companion to Renaissance Europe, 1390–1530'', (Routledge, 1999), 76. until 1491 when the young king turned 21 years of age. During Anne's regency, the great lords rebelled against royal centralisation efforts in a conflict known as the Mad War (1485–1488), which resulted in a victory for the royal government. In a remarkable stroke of audacity, Charles married Anne of Brittany in 1491 after she had already been married by proxy to the Habsburg Holy Roman Emperor Maximilian I in a ceremony of questionable validity. Preoccupied by the problematic succession in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerhard Dorn
Gerhard Dorn (c. 1530 – 1584) was a Belgian philosopher, translator, alchemist, physician and bibliophile. Biography The details of Gerhard Dorn's early life, along with those of many other 16th century personalities, are lost to history. It is known that he was born about 1530 in Mechelen, which is part of modern-day Belgium's Antwerp Province. He studied with Adam von Bodenstein, to whom his first book is dedicated and began publishing books from around 1565. He used John Dee's personal glyph from his 1564 book, the ''Monas Hieroglyphica'', on the title page of his ''Chymisticum artificium''. Together with von Bodenstein, he rescued many of Paracelsus's manuscripts and printed them for the first time. He also translated many of them into Latin for the Basel publisher Pietro Perna and lived in Basel during the 1570s and Frankfurt in the early 1580s, where he died when he was in his mid-fifties. Philosophy Dorn claimed to have found a better philosophy and a more Chri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urine
Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excretion, excreted from the body through the urethra. Cell (biology), Cellular metabolism generates many by-products that are rich in nitrogen and must be clearance (medicine), cleared from the Circulatory system, bloodstream, such as urea, uric acid, and creatinine. These by-products are expelled from the body during urination, which is the primary method for excreting water-soluble chemicals from the body. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, Reuse of excreta, urine can be used as a fertilizer. Some animals use it to territory (animal)#Scent marking, mark their territories. Historically, aged or fermented urine (kn ...

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crystallization
Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation. Crystallization occurs in two major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc. The majority of minerals and organic molecules crystallize easily, and the resulting crystals are g ...

Padua
Padua ( ; it, Padova ; vec, Pàdova) is a city and ''comune'' in Veneto, northern Italy. Padua is on the river Bacchiglione, west of Venice. It is the capital of the province of Padua.
