Liber Ignium
The ''Liber Ignium ad Comburendos Hostes'' (translated as ''On the Use of Fire to Conflagrate the Enemy'', or ''Book of Fires for the Burning of Enemies'', and abbreviated as ''Book of Fires'') is a medieval collection of recipes for incendiary weapons, including Greek fire and gunpowder, written in Latin and allegedly written by a certain Marcus Graecus ("Mark the Greek")—a person whose existence is debated by scholars. The work has been subjected to numerous academic analyses, resulting in contradictory conclusions vis-a-vis origin and influence on its contemporaries.Partington, James Riddick. A History of Greek Fire and Gunpowder, The Johns Hopkins University Press, 1998, pp. 58-60 One of the most influential studies of the ''Liber Ignium'' was conducted by Marcellin Berthelot which is cited in 20th century works on the topic. Contents The ''Liber Ignium'' is a collection of 35 recipes without any internal classification, as it was typical of "secret recipe" list of the er ...

Medieval
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the Post-classical, post-classical period of World history (field), global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern history, modern period. The medieval period is itself subdivided into the Early Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the ...

Encyclopædia Britannica Eleventh Edition
The ''Encyclopædia Britannica'' Eleventh Edition (1910–1911) is a 29-volume reference work, an edition of the ''Encyclopædia Britannica''. It was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time. This edition of the encyclopaedia, containing 40,000 entries, has entered the public domain and is easily available on the Internet. Its use in modern scholarship and as a reliable source has been deemed problematic due to the outdated nature of some of its content. Modern scholars have deemed some articles as cultural artifacts of the 19th and early 20th centuries. Background The 1911 eleventh edition was assembled with the management of American publisher Horace Everett Hooper. Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Originally, Hooper bought the rights to th ...

Alchemical Documents
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 these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Beckmann
Johann Beckmann (1739–1811) was a German scientific author and coiner of the word technology, to mean the science of trades. He was the first man to teach technology and write about it as an academic subject. Life He was born on 4 June 1739 at Hoya in Hanover, where his father was postmaster and receiver of taxes. He was educated at Stade and the university of Göttingen, where he studied theology, mathematics, physics, natural history, and public finance and administration. After completing his studies, in 1762 he made a study tour through Brunswick and the Dutch Republic examining mines, factories, natural history museums, private collections, universities and their professors. The death of his mother in 1762 having deprived him of his means of support, he went in 1763 on the invitation of the pastor of the Lutheran community, Anton Friedrich Büsching, the founder of the modern historic statistical method of geography, to teach natural history in the Lutheran gymnasium St. ...

Albertus Magnus
Albertus Magnus (c. 1200 – 15 November 1280), also known as Saint Albert the Great or Albert of Cologne, was a German Dominican friar, philosopher, scientist, and bishop. Later canonised as a Catholic saint, he was known during his lifetime as ''Doctor universalis'' and ''Doctor expertus'' and, late in his life, the sobriquet ''Magnus'' was appended to his name. Scholars such as James A. Weisheipl and Joachim R. Söder have referred to him as the greatest German philosopher and theologian of the Middle Ages. The Catholic Church distinguishes him as one of the 37 Doctors of the Church. Biography It seems likely that Albert was born sometime before 1200, given well-attested evidence that he was aged over 80 on his death in 1280. Two later sources say that Albert was about 87 on his death, which has led 1193 to be commonly given as the date of Albert's birth, but this information does not have enough evidence to be confirmed. Albert was probably born in Lauingen (now in Bav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Bacon
Roger Bacon (; la, Rogerus or ', also '' Rogerus''; ), also known by the scholastic accolade ''Doctor Mirabilis'', was a medieval English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism. In the early modern era, he was regarded as a wizard and particularly famed for the story of his mechanical or necromantic brazen head. He is sometimes credited (mainly since the 19th century) as one of the earliest European advocates of the modern scientific method, along with his teacher Robert Grosseteste. Bacon applied the empirical method of Ibn al-Haytham (Alhazen) to observations in texts attributed to Aristotle. Bacon discovered the importance of empirical testing when the results he obtained were different from those that would have been predicted by Aristotle. His linguistic work has been heralded for its early exposition of a universal grammar, and 21st-century re-evaluations emphasise that Bacon was essentially a medi ...

T'oung Pao
''T’oung Pao'' (; ), founded in 1890, is a Dutch journal and the oldest international journal of sinology. It is published by the publisher E. J. Brill. ''T'oung Paos original full title was ''T’oung Pao ou Archives pour servir à l’étude de l’histoire, des langues, la geographie et l’ethnographie de l’Asie Orientale (Chine, Japon, Corée, Indo-Chine, Asie Centrale et Malaisie)'' ("Tongbao or Archives for Use in the Study of the History, Languages, Geography, and Ethnography of East Asia hina, Japan, Korea, Indochina, Central Asia, and Malaysia">Indochina.html" ;"title="hina, Japan, Korea, Indochina">hina, Japan, Korea, Indochina, Central Asia, and Malaysia).

The term is used by modern historians for the former Islamic states in modern Spain and Portugal. At its greatest geographical extent, it occupied most of the peninsula and a part of present-day southern France, Septimania (8th century). For nearly a hundred years, from the 9th century to the 10th, al-Andalus extended its presence from Fraxinetum into the Alps with a series of organized raids and chronic banditry. The name describes the different Arab and Muslim states that controlled these territories at various times between 711 and 1492. These boundaries changed constantly as the Christian Reconquista progressed,"Para los autores árabes medievales, el término Al-Andalus designa la totalidad ...
