Trefoil
A trefoil () is a graphic form composed of the outline of three overlapping rings, used in architecture and Christian symbolism, among other areas. The term is also applied to other symbols with a threefold shape. A similar shape with four rings is called a quatrefoil. Architecture Ornamentation 'Trefoil' is a term in Gothic architecture given to the ornamental foliation or cusping introduced in the heads of window-lights, tracery, and panellings, in which the centre takes the form of a three-lobed leaf (formed from three partially overlapping circles). One of the earliest examples is in the plate tracery at Winchester Cathedral (1222–1235). The fourfold version of an architectural trefoil is a quatrefoil. A simple trefoil shape in itself can be symbolic of the Trinity, while a trefoil combined with an equilateral triangle was also a moderately common symbol of the Christian Trinity during the late Middle Ages in some parts of Europe, similar to a barbed quatrefoil.

Quatrefoil
A quatrefoil (anciently caterfoil) is a decorative element consisting of a symmetrical shape which forms the overall outline of four partially overlapping circles of the same diameter. It is found in art, architecture, heraldry and traditional Christian symbolism. The word 'quatrefoil' means "four leaves", from the Latin , "four", plus , "leaf"; the term refers specifically to a four-leafed clover, but applies in general to four-lobed shapes in various contexts. In recent years, several luxury brands have attempted to fraudulently assert creative rights related to the symbol, which naturally predates any of those brands' creative development. A similar shape with three rings is called a trefoil. History The quatrefoil enjoyed its peak popularity during the Gothic and Renaissance eras. It is most commonly found as tracery, mainly in Gothic architecture, where a quatrefoil often may be seen at the top of a Gothic arch, sometimes filled with stained glass. Although the design is ...

Hazard Symbol
Hazard symbols or warning symbols are recognisable symbols designed to warn about hazardous or dangerous materials, locations, or objects, including electric currents, poisons, and radioactivity. The use of hazard symbols is often regulated by law and directed by standards organizations. Hazard symbols may appear with different colors, backgrounds, borders, and supplemental information in order to specify the type of hazard and the level of threat (for example, toxicity classes). Warning symbols are used in many places in lieu of or addition to written warnings as they are quickly recognized (faster than reading a written warning) and more commonly understood (the same symbol can be recognized as having the same meaning to speakers of different languages). List of common symbols Tape with yellow and black diagonal stripes is commonly used as a generic hazard warning. This can be in the form of barricade tape, or as a self-adhesive tape for marking floor areas and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clover
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include ''Melilotus'' (sweet clover) and '' Medicago'' ( alfalfa or Calva ...

Tracery
Tracery is an architectural device by which windows (or screens, panels, and vaults) are divided into sections of various proportions by stone ''bars'' or ''ribs'' of moulding. Most commonly, it refers to the stonework elements that support the glass in a window. The term probably derives from the tracing floors on which the complex patterns of windows were laid out in late Gothic architecture. Tracery can also be found on the interior of buildings and the exterior. There are two main types: plate tracery and the later bar tracery. Honour, H. and J. Fleming, (2009) ''A World History of Art''. 7th edn. London: Laurence King Publishing, p. 948. The evolving style from Romanesque to Gothic architecture and changing features, such as the thinning of lateral walls and enlarging of windows, led to the innovation of tracery. The earliest form of tracery, called plate tracery, began as openings that were pierced from a stone slab. Bar tracery was then implemented, having derived from ...

Foil (architecture)
A foil is an architectural device based on a symmetrical rendering of leaf shapes, defined by overlapping circles of the same diameter that produce a series of cusps to make a lobe. Typically, the number of cusps can be three (trefoil), four ( quatrefoil), five (cinquefoil), or a larger number (multifoil).

Megalithic Temples Of Malta
The Megalithic Temples of Malta ( mt, It-Tempji Megalitiċi ta' Malta) are several prehistoric temples, some of which are UNESCO World Heritage Sites, built during three distinct periods approximately between 3600 BC and 2500 BC on the island country of Malta. They had been claimed as the oldest free-standing structures on Earth until the discovery of Göbekli Tepe. Archaeologists believe that these megalithic complexes are the result of local innovations in a process of cultural evolution. This led to the building of several temples of the Ġgantija phase (3600–3000 BC), culminating in the large Tarxien temple complex, which remained in use until 2500 BC. After this date, the temple-building culture disappeared. The Ġgantija temples were listed as a UNESCO World Heritage Site in 1980. In 1992, the UNESCO Committee further extended the existing listing to include five other megalithic temple sites. These are Ħaġar Qim (in Qrendi), Mnajdra (in Qrendi), Ta' Ħaġrat Temples (i ...

Fallout Shelter
A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War. During a nuclear explosion, matter vaporized in the resulting fireball is exposed to neutrons from the explosion, absorbs them, and becomes radioactive. When this material condenses in the rain, it forms dust and light sandy materials that resemble ground pumice. The fallout emits alpha and beta particles, as well as gamma rays. Much of this highly radioactive material falls to Earth, subjecting anything within the line of sight to radiation, becoming a significant hazard. A fallout shelter is designed to allow its occupants to minimize exposure to harmful fallout until radioactivity has decayed to a safer level. History North America During the Cold War, many countries built fallout shelters for high-ranking government officials and cru ...

Gothic Architecture
Gothic architecture (or pointed architecture) is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (lit. French work); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the architecture of classical antiquity. The defining design element of Gothic architecture is the pointed or ogival arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Saint-Denis, near Paris, the choir was reconstructed between 1140 and 1144, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girl Guiding And Girl Scouting
A Girl Guide or Girl Scout is a member of a section of some Guiding organisations who is between the ages of 10 and 14. Age limits are different in each organisation. The term Girl Scout is used in the United States and several East Asian countries. The two terms are used synonymously within this article. Girl Guides are organised into units/troops averaging 15–30 girls under guidance of a team of leaders. Units subdivide into patrols of about six Guides and engage in outdoor and special interest activities. Units may affiliate with national and international organisations. Some units, especially in Europe, have been co-educational since the 1970s, allowing boys and girls to work together as Scouts. There are other programme sections for older and younger girls. Foundation Following the origin of the Boy Scouts in 1907 many girls took up Scouting. A group of Girl Scouts were prominent at the Crystal Palace Rally in 1909.
