Medieval Stained Glass
Medieval stained glass is the colored and painted glass of Middle Ages, medieval Europe from the 10th century to the 16th century. For much of this period stained glass windows were the major pictorial art form, particularly in France in the Middle Ages, northern France, Holy Roman Empire, Germany and England in the Middle Ages, England, where windows tended to be larger than in southern Europe (in Italy, for example, frescos were more common). In some countries, such as Medieval stained glass in Sweden, Sweden and England, only a small number of original stained windows have survived to this day. Stained glass windows were used predominantly in churches, but were also found in wealthy domestic settings and public buildings such as town halls, though surviving examples of secular glass are rather rare in comparison. Stained glass windows were used in churches to enhance their beauty and to inform the viewer through narrative or symbolism. The subject matter was generally religious ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of 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 period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised 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 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Glass
Forest glass (''Waldglas'' in German) is a type of medieval glass produced in northwestern and central Europe from approximately 1000–1700 AD using wood ash and sand as the main raw materials and made in factories known as glasshouses in forest areas.Tait, H., 1991. It is characterized by a variety of greenish-yellow colors, the earlier products often being of crude design and poor quality, and was used mainly for everyday vessels and increasingly for ecclesiastical stained glass windows. Its composition and manufacture contrast sharply with Roman and pre-Roman glassmaking, centered on Mediterranean and contemporaneous Byzantine and Islamic glassmaking to the east. History While under Roman rule, the raw materials and manufacturing methods of northern Europe were those of the Roman tradition, using the mineral natron. For several centuries after the fall of the Western Roman Empire, around 450 AD, recycling of Roman glass formed the major part of the local industry and glass ...

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , commonly found in nature as quartz. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product. Examples include fused quartz, fumed silica, opal, and aerogels. It is used in structural materials, microelectronics, and as components in the food and pharmaceutical industries. All forms are white or colorless, although impure samples can be colored. Silicon dioxide is a common fundamental constituent of glass. Structure In the majority of silicon dioxides, the silicon atom shows Tetrahedral molecular geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. ...

Iron Oxide
An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the " earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172. Stoichiometries Iron oxides feature as ferrous ( Fe(II)) or ferric ( Fe(III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. * Oxides of FeII ** FeO: ir ...

Loire Valley
The Loire Valley (, ), spanning , is a valley located in the middle stretch of the Loire river in central France, in both the administrative regions Pays de la Loire and Centre-Val de Loire. The area of the Loire Valley comprises about . It is referred to as the ''Cradle of the French'' and the ''Garden of France'' due to the abundance of vineyards, fruit orchards (such as cherries), and artichoke, and asparagus fields, which line the banks of the river. Notable for its historic towns, architecture, and wines, the valley has been inhabited since the Middle Palaeolithic period. In 2000, UNESCO added the central part of the Loire River valley to its list of World Heritage Sites. Geography and climate The valley includes historic towns such as Amboise, Angers, Blois, Chinon, Montsoreau, Orléans, Saumur, and Tours. The climate is favorable most of the year, the river often acting as a line of demarcation in France's weather between the northern climate and the southern. The riv ...

Seine
The Seine ( , ) is a river in northern France. Its drainage basin is in the Paris Basin (a geological relative lowland) covering most of northern France. It rises at Source-Seine, northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and into the English Channel at Le Havre (and Honfleur on the left bank). It is navigable by ocean-going vessels as far as Rouen, from the sea. Over 60 percent of its length, as far as Burgundy (region), Burgundy, is negotiable by large barges and most tour boats, and nearly its whole length is available for recreational boating; Bateaux Mouches, excursion boats offer sightseeing tours of the river banks in the capital city, Paris. There are 37 List of bridges in Paris#Seine, bridges in Paris across the Seine (the most famous of which are the Pont Alexandre III and the Pont Neuf) and dozens List of crossings of the River Seine, more outside the city.

Flanders
Flanders ( or ; ) is the Dutch language, Dutch-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Flemings, Fleming, while the corresponding adjective is Flemish people, Flemish, which can also refer to the collective of Dutch dialects spoken in that area, or more generally the Belgian variant of Standard Dutch.

Rhine
The Rhine ( ) is one of the List of rivers of Europe, major rivers in Europe. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein border, then part of the Austria–Switzerland border, Swiss-Austrian border. From Lake Constance downstream, it forms part of the Germany-Switzerland border, Swiss-German border. After that the Rhine defines much of the Franco-German border. It then flows in a mostly northerly direction through the German Rhineland. Finally, the Rhine turns to flow predominantly west to enter the Netherlands, eventually emptying into the North Sea. It drains an area of 185,000 km2. Its name derives from the Gaulish language, Gaulish ''Rēnos''. There are two States of Germany, German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate, in addition to several districts of Germany, districts (e.g. Rhein-Sieg-Kreis, Rhein-Sieg).

Lorraine
Lorraine, also , ; ; Lorrain: ''Louréne''; Lorraine Franconian: ''Lottringe''; ; ; is a cultural and historical region in Eastern France, now located in the administrative region of Grand Est. Its name stems from the medieval kingdom of Lotharingia (855–959 AD), which in turn was named after either Emperor Lothair I or King Lothair II. Lorraine, originally the southern or "upper" part of this kingdom, came to be ruled by the Holy Roman Empire as the Duchy of Lorraine before the Kingdom of France annexed it in 1766. From 1982 until January 2016, Lorraine was an administrative region of France. In 2016, under a reorganisation, it became part of the new region Grand Est. As a region in modern France, Lorraine consisted of the four departments Meurthe-et-Moselle, Meuse, Moselle and Vosges (from a historical point of view the Haute-Marne department is also located in the region), containing 2,337 communes. Metz is the regional prefecture. The largest metropolitan area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burgundy
Burgundy ( ; ; Burgundian: ''Bregogne'') is a historical territory and former administrative region and province of east-central France. The province was once home to the Dukes of Burgundy from the early 11th until the late 15th century. The capital, Dijon, was wealthy and powerful, being a major European centre of art and science, and of Western Monasticism. In early Modern Europe, Burgundy was a focal point of courtly culture that set the fashion for European royal houses and their court. The Duchy of Burgundy was a key in the transformation of the Middle Ages towards early modern Europe. Upon the 9th-century partitions of the Kingdom of Burgundy, the lands and remnants partitioned to the Kingdom of France were reduced to a ducal rank by King Robert II of France in 1004. The House of Burgundy, a cadet branch of the House of Capet, ruled over a territory that roughly conformed to the borders and territories of the modern administrative region of Burgundy.
