Heater Shield
The heater shield or heater-shaped shield is a form of European medieval shield, developing from the early medieval kite shield in the late 12th century in response to the declining importance of the shield in combat thanks to improvements in leg armour. The term is a neologism, created by Antiquarian, Victorian antiquarians due to the shape's resemblance to a clothes iron. Examples are depicted in the great seal of Richard I and John. Details Smaller than the kite shield, it was more manageable and could be used either mounted or on foot.''Medieval Swordsmanship'', p. 102 From the 15th century, it evolved into highly specialized jousting shields, often containing a ''bouche'', a notch or "mouth" for the lance to pass through. As plate armour began to cover more and more of the body, the shield grew correspondingly smaller. By the mid 14th century it was hardly seen outside of tournaments. Heater shields were typically made from thin wood overlaid with leather. They wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geometric Construction Of Heater Shield ENG
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geometries wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lance
A lance is a spear designed to be used by a mounted warrior or cavalry soldier ( lancer). In ancient and medieval warfare, it evolved into the leading weapon in cavalry charges, and was unsuited for throwing or for repeated thrusting, unlike similar weapons of the javelin and pike family typically used by infantry. Lances were often equipped with a vamplate, a small circular plate to prevent the hand sliding up the shaft upon impact, and beginning in the late 14th century were used in conjunction with a lance rest attached to the breastplate. Though best known as a military and sporting weapon carried by European knights and men-at-arms, the use of lances was widespread throughout Asia, the Middle East, and North Africa wherever suitable mounts were available. Lancers of the medieval period also carried secondary weapons such as swords, battle axes, war hammers, maces and daggers for use in hand-to-hand combat, since the lance was often a one-use-per-engagement weapon; assumi ...

Escutcheon (heraldry)
In heraldry, an escutcheon () is a shield that forms the main or focal element in an Achievement (heraldry), achievement of arms. The word can be used in two related senses. In the first sense, an escutcheon is the shield upon which a coat of arms is displayed. In the second sense, an escutcheon can itself be a charge (heraldry), charge within a coat of arms. Escutcheon shapes are derived from actual shields that were used by knights in combat, and thus are varied and developed by region and by era. Since shields have been regarded as military equipment appropriate for men only, British ladies customarily bear their arms upon a Lozenge (heraldry), lozenge, or diamond-shape, while clergymen and ladies in continental Europe bear their arms upon a Cartouche (design), cartouche, or oval. Other shapes are also in use, such as the roundel (heraldry), roundel commonly used for arms granted to Aboriginal Canadians by the Canadian Heraldic Authority, or the Nguni shield used in Coats of ar ...

Knight
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the church or the country, especially in a military capacity. Knighthood finds origins in the Greek ''hippeis'' and '' hoplite'' (ἱππεῖς) and Roman '' eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. Knighthood in the Middle Ages was closely linked with horsemanship (and especially the joust) from its origins in th ...

Guige
A guige ( /ɡiːʒ/, /ɡiːd͡ʒ/) is a long strap, typically made of leather, used to hang a shield on the shoulder or neck when not in use. Used in combat, it freed a soldier to use a weapon requiring two hands without discarding the shield; the shield could then be easily retrieved when needed. Some guiges had a buckle to adjust the length. A guige could be attached to the shield anywhere along its rim, and could run horizontally, vertically, or diagonally across the diameter of the shield. Most information about the usage of guiges comes from various Medieval works of art, such as the Bayeux Tapestry. Frequently in heraldry shields are depicted hanging from guige straps. See also * Enarmes Enarmes are the leather gripping straps attached to the back of shields throughout the Medieval period. Enarmes were held in place by riveting through the leather and the facing of the shield, and reinforced with small, square-cut washers. Enarm ... References Medieval shield ...

Parchment
Parchment is a writing material made from specially prepared untanned skins of animals—primarily sheep, calves, and goats. It has been used as a writing medium for over two millennia. Vellum is a finer quality parchment made from the skins of young animals such as lambs and young calves. It may be called animal membrane by libraries and museums that wish to avoid distinguishing between ''parchment'' and the more-restricted term ''vellum'' (see below). Parchment and vellum Today the term ''parchment'' is often used in non-technical contexts to refer to any animal skin, particularly goat, sheep or cow, that has been scraped or dried under tension. The term originally referred only to the skin of sheep and, occasionally, goats. The equivalent material made from calfskin, which was of finer quality, was known as ''vellum'' (from the Old French or , and ultimately from the Latin , meaning a calf); while the finest of all was ''uterine vellum'', taken from a calf foetus or still ...

Canvas
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, shelters, as a support for oil painting and for other items for which sturdiness is required, as well as in such fashion objects as handbags, electronic device cases, and shoes. It is popularly used by artists as a painting surface, typically stretched across a wooden frame. Modern canvas is usually made of cotton or linen, or sometimes polyvinyl chloride (PVC), although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven. The term ''duck'' comes from the Dutch word for cloth, ''doek''. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a graded number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gesso
Gesso (; "chalk", from the la, gypsum, from el, γύψος) is a white paint mixture consisting of a binder mixed with chalk, gypsum, pigment, or any combination of these. It is used in painting as a preparation for any number of substrates such as wood panels, canvas and sculpture as a base for paint and other materials that are applied over it. Description "''Gesso''", also known "glue gesso" or "Italian gesso", is a traditional mix of an animal glue binder (usually rabbit-skin glue), chalk, and white pigment, used to coat rigid surfaces such as wooden painting panels or masonite as a permanent absorbent primer substrate for painting. The colour of gesso is usually white or off-white. Its absorbency makes it work with all painting media, including water-based media, different types of tempera and oil paint. It is also used as a base on three-dimensional surfaces for the application of paint or gold leaf. Mixing and applying it is a craft in itself, as it is usually applie ...

Canterbury Cathedral
Canterbury Cathedral in Canterbury, Kent, is one of the oldest and most famous Christian structures in England. It forms part of a World Heritage Site. It is the cathedral of the Archbishop of Canterbury, currently Justin Welby, leader of the Church of England and symbolic leader of the worldwide Anglican Communion. Its formal title is the Cathedral and Metropolitical Church of Christ at Canterbury. Founded in 597, the cathedral was completely rebuilt between 1070 and 1077. The east end was greatly enlarged at the beginning of the 12th century and largely rebuilt in the Gothic style following a fire in 1174, with significant eastward extensions to accommodate the flow of pilgrims visiting the shrine of Thomas Becket, the archbishop who was murdered in the cathedral in 1170. The Norman nave and transepts survived until the late 14th century when they were demolished to make way for the present structures. Before the English Reformation the cathedral was part of a Benedictine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward, The Black Prince
Edward of Woodstock, known to history as the Black Prince (15 June 1330 – 8 June 1376), was the eldest son of King Edward III of England, and the heir apparent to the English throne. He died before his father and so his son, Richard II, succeeded to the throne instead. Edward nevertheless earned distinction as one of the most successful English commanders during the Hundred Years' War, being regarded by his English contemporaries as a model of chivalry and one of the greatest knights of his age. Edward was made Duke of Cornwall, the first English dukedom, in 1337. He was guardian of the kingdom in his father's absence in 1338, 1340, and 1342. He was created Prince of Wales in 1343 and knighted by his father at La Hougue in 1346. In 1346, Prince Edward commanded the vanguard at the Battle of Crécy, his father intentionally leaving him to win the battle. He took part in Edward III's 1349 Calais expedition. In 1355, he was appointed the king's lieutenant in Gascony, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...
