Lapis Armenus
Lapis armenus, also known as Armenian stone or lapis stellatus, in natural history, is a variety of precious stone, resembling lapis lazuli, except that it is softer, and instead of veins of pyrite, is intermixed with green. "The Armenian stone" is so similar to ''lapis lazuli'' that it has often not been distinguished from it; ''Webster's Revised Unabridged Dictionary'' for instance treats the two terms as synonyms. The ''Dictionary of Traded Goods and Commodities 1550-1820'' defines ''lapis armenus'' as Armenian stone, or azurite, a naturally occurring basic carbonate, originally from Armenia, but later from Germany, from which was prepared. It was often found in association with another copper carbonate, malachite from which was prepared... Probably because they were both blue, blue bice was sometimes misinterpreted to mean . Chemically however lapis lazuli is not at all similar. Herman Boerhaave believed it rather to rank among semi-metals, and supposed it was composed of ...

Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Of Tyrol
The (Princely) County of Tyrol was an estate of the Holy Roman Empire established about 1140. After 1253, it was ruled by the House of Gorizia and from 1363 by the House of Habsburg. In 1804, the County of Tyrol, unified with the secularised prince-bishoprics of Trent and Brixen, became a crown land of the Austrian Empire. From 1867, it was a Cisleithanian crown land of Austria-Hungary. Today the territory of the historic crown land is divided between the Italian autonomous region of Trentino-Alto Adige/Südtirol and the Austrian state of Tyrol. The two parts are today associated again in the Tyrol–South Tyrol–Trentino Euroregion. History Establishment At least since German king Otto I had conquered the former Lombard kingdom of Italy in 961 and had himself crowned Holy Roman Emperor in Rome, the principal passes of the Eastern Alps had become an important transit area. The German monarchs regularly travelled across Brenner or Reschen Pass on their Italian expedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encyclopedia Perthensis
An encyclopedia (American English) or encyclopædia ( British English) is a reference work or compendium providing summaries of knowledge either general or special to a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on ''factual information'' concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.Béjoint, Henri (2000)''Modern Lexicography'', pp. 30–31. Oxford University Press. Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or ...

The Anatomy Of Melancholy
''The Anatomy of Melancholy'' (full title: ''The Anatomy of Melancholy, What it is: With all the Kinds, Causes, Symptomes, Prognostickes, and Several Cures of it. In Three Maine Partitions with their several Sections, Members, and Subsections. Philosophically, Medicinally, Historically, Opened and Cut Up'') is a book by Robert Burton, first published in 1621, but republished five more times over the next seventeen years with massive alterations and expansions. Overview On its surface, the book is presented as a medical textbook in which Burton applies his vast and varied learning, in the scholastic manner, to the subject of melancholia (or clinical depression). Although presented as a medical text, ''The Anatomy of Melancholy'' is as much a ''sui generis'' (unique) work of literature as it is a scientific or philosophical text, as Burton covers far more than the nomitive subject. ''Anatomy'' uses melancholy as a lens through which all human emotion and thought may be scrutinize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melancholia
Melancholia or melancholy (from el, µέλαινα χολή ',Burton, Bk. I, p. 147 meaning black bile) is a concept found throughout ancient, medieval and premodern medicine in Europe that describes a condition characterized by markedly depressed mood, bodily complaints, and sometimes hallucinations and delusions. Melancholy was regarded as one of the four temperaments matching the four humours. Until the 18th century, doctors and other scholars classified melancholic conditions as such by their perceived common causean excess of a notional fluid known as "black bile", which was commonly linked to the spleen. Between the late 18th and late 19th centuries, ''melancholia'' was a common medical diagnosis, and modern concepts of depression as a mood disorder eventually arose from this historical context. Related terms used in historical medicine include lugubriousness (from Latin '' lugere'': "to mourn"), moroseness (from Latin '' morosus'': "self-will or fastidious habit"), ...

Azure (color)
Azure ( , ) is the color between cyan and blue on the spectrum of visible light. It is often described as the color of the sky on a clear day. On the RGB color wheel, "azure" ( hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a 50% of green light to a 100% of blue light. In the X11 color system, which became a model for early web colors, azure is depicted as a pale cyan or white cyan. Etymology and history The color azure ultimately takes its name from the intense blue mineral lapis lazuli. ' is the Latin word for "stone" and ' is the genitive form of the Medieval Latin ', which is taken from the Arabic ''lāzaward'', itself from the Persian ''lāžaward'', which is the name of the stone in Persian and also of a place where lapis lazuli was mined. The name of the stone came to be associate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German Tyrol
German Tyrol (german: Deutschtirol; it, Tirolo tedesco) is a historical region in the Alps now divided between Austria and Italy. It includes largely ethnic German areas of historical County of Tyrol: the Austrian state of Tyrol (consisting of North Tyrol and East Tyrol) and the province of South Tyrol but not the largely Italian-speaking province of Trentino (formerly '' Welschtirol''). History German Tyrol was historically an integral part of the Habsburg constituent Princely County of Tyrol but, with the imminent collapse of Habsburg Austria-Hungary at the end of World War I, areas of the empire with an ethnic German majority began to take actions to form a new state.
