Friezes
In classical architecture, the frieze is the wide central section of an entablature and may be plain in the Ionic or Corinthian orders, or decorated with bas-reliefs. Paterae are also usually used to decorate friezes. Even when neither columns nor pilasters are expressed, on an astylar wall it lies upon the architrave ("main beam") and is capped by the moldings of the cornice. A frieze can be found on many Greek and Roman buildings, the Parthenon Frieze being the most famous, and perhaps the most elaborate. In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long stretch of painted, sculpted or even calligraphic decoration in such a position, normally above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made may be plasterwork, carved wood or other decorative medium. More loosely, "frieze" is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parthenon Frieze
The Parthenon frieze is the low-relief Mount Pentelicus#Pentelic marble, Pentelic marble sculpture created to adorn the upper part of the Parthenon's Cella, naos. It was sculpted between and 437 BC, most likely under the direction of Phidias. Of the 160 meters (524 ft) of the original frieze, 128 meters (420 ft) survives—some 80 percent. The rest is known only from the drawings attributed to French artist Jacques Carrey in 1674, thirteen years before the Parthenon#Destruction, Venetian bombardment that ruined the temple. Along with the 64 Metopes of the Parthenon and 28 figures Pediments of the Parthenon, it forms the bulk of surviving sculpture from the building. All of the frieze has been removed from the Parthenon. 56 blocks of the frieze are at the British Museum in London (forming the major part of the Elgin Marbles); 40 blocks are in the Acropolis Museum in Athens, and the remainder of fragments shared between six other institutions. Casts of the frieze m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picture Rail
Moulding (British English), or molding (American English), also coving (in United Kingdom, Australia), is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster. A "plain" moulding has right-angled upper and lower edges. A "sprung" moulding has upper and lower edges that bevel towards its rear, allowing mounting between two non-parallel planes (such as a wall and a ceiling), with an open space behind. Mouldings may be decorated with paterae as long, uninterrupted elements may be boring for eyes. Types Decorative mouldings have been made of wood, stone and cement. Recently mouldings have been made of extruded polyvinyl chloride (PV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persepolis
Persepolis (; ; ) was the ceremonial capital of the Achaemenid Empire (). It is situated in the plains of Marvdasht, encircled by the southern Zagros mountains, Fars province of Iran. It is one of the key Iranian cultural heritage sites and a UNESCO World Heritage Site. The earliest remains of Persepolis date back to 515 BC. The city, acting as a major center for the empire, housed a palace complex and citadel designed to serve as the focal point for governance and ceremonial activities. It exemplifies the Achaemenid style of architecture. The complex was taken by the army of Alexander the Great in 330 BC, and soon after, its wooden parts were completely destroyed by fire, likely deliberately. The function of Persepolis remains unclear. It was not one of the largest cities in ancient Iran, let alone the rest of the empire, but appears to have been a grand ceremonial complex that was only occupied seasonally; the complex was raised high on a walled platform, with five "palac ...

Frieze Pattern
In mathematics, a frieze or frieze pattern is a two-dimensional design that repeats in one direction. The term is derived from friezes in architecture and decorative arts, where such repeating patterns are often used. Frieze patterns can be classified into seven types according to their symmetries. The set of symmetry, symmetries of a frieze pattern is called a frieze group. Frieze groups are two-dimensional line groups, having repetition in only one direction. They are related to the more complex wallpaper groups, which classify patterns that are repetitive in two directions, and crystallographic groups, which classify patterns that are repetitive in three directions. History Mathematical friezes have their origins in the formulas for the '' pentagramma mirificum'' found by Carl Friedrich Gauss in 1843 and Harold Scott MacDonald Coxeter's study of symmetries in the mid-20th century. Frieze patterns were formally introduced by Coxeter in 1971. In the 1970s to 1980s, frieze patt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Northern Mannerism
Northern Mannerism is the form of Mannerism found in the visual arts north of the Alps in the 16th and early 17th centuries. Styles largely derived from Italian Mannerism were found in the Netherlands and elsewhere from around the mid-century, especially Mannerist ornament in architecture; this article concentrates on those times and places where Northern Mannerism generated its most original and distinctive work. The three main centres of the style were in France, especially in the period 1530–1550, in Prague from 1576, and in the Netherlands from the 1580s—the first two phases very much led by royal patronage. In the last 15 years of the century, the style, by then becoming outdated in Italy, was widespread across northern Europe, spread in large part through prints. In painting, it tended to recede rapidly in the new century, under the new influence of Caravaggio and the early Baroque, but in architecture and the decorative arts, its influence was more sustained.

Agora
The agora (; , romanized: ', meaning "market" in Modern Greek) was a central public space in ancient Ancient Greece, Greek polis, city-states. The literal meaning of the word "agora" is "gathering place" or "assembly". The agora was the center of the athletic, artistic, business, social, spiritual, and political life in the city. The Ancient Agora of Athens is the best-known example. Origins Early in Greek history (10th–4th centuries BC), free-born citizens would gather in the agora for military duty or to hear statements of the ruling king or council. Later, the agora also served as a marketplace, where merchants kept stalls or shops to sell their goods amid Arcade (architecture), arcades. This attracted artisans who built workshops nearby. From these twin functions of the agora as a political and a commercial spot came the two Greek verbs , ''agorázō'', "I shop", and , ''agoreúō'', "I speak in public".

Tower Of The Winds
The Tower of the Winds, known as the in Greek, and by #Names, other names, is an octagonal Pentelic marble tower in the Roman Agora in Athens, named after the eight large reliefs of wind gods around its top. Its date is uncertain, but was completed by about 50 BC, at the latest, as it was mentioned by Marcus Terentius Varro, Varro in his ''De re Rustica'' of about 37 BC. It is "one of the very small number of buildings from classical antiquity that still stands virtually intact", as it has been continuously occupied for a series of different functions. Formerly topped by a wind vane, it is the only surviving horologium or clock tower from classical antiquity. It also housed a large water clock and incorporated sundials placed prominently on its exterior faces; "citizens were thus able by using this building to orient themselves in space and time. Architecture, sculpture and the new science were perfectly integrated". According to A. W. Lawrence, "the originality of this buildin ...

Plasterwork
Plasterwork is construction or ornamentation done with plaster, such as a layer of plaster on an interior or exterior wall structure, or plaster Molding (decorative), decorative moldings on ceilings or walls. This is also sometimes called pargeting. The process of creating plasterwork, called plastering or rendering, has been used in building construction for centuries. For the art history of three-dimensional plaster, see stucco. History The earliest plasters known to us were lime-based. Around 7500 BC, the people of 'Ain Ghazal in Jordan used lime mixed with unheated crushed limestone to make plaster which was used on a large scale for covering walls, floors, and hearths in their houses. Often, walls and floors were decorated with red, finger-painted patterns and designs. In ancient India and China, renders in clay and gypsum plasters were used to produce a smooth surface over rough stone or mud brick walls, while in early Egyptian tombs, walls were coated with lime and gyps ...

Calligraphy
Calligraphy () is a visual art related to writing. It is the design and execution of lettering with a pen, ink brush, or other writing instruments. Contemporary calligraphic practice can be defined as "the art of giving form to signs in an expressive, harmonious, and skillful manner". In East Asia and the Islamic world, where written forms allow for greater flexibility, calligraphy is regarded as a significant art form, and the form it takes may be affected by the meaning of the text or the individual words. Modern Western calligraphy ranges from functional inscriptions and designs to fine-art pieces where the legibility of letters varies. Classical calligraphy differs from type design and non-classical hand-lettering, though a calligrapher may practice both. CD-ROM Western calligraphy continues to flourish in the forms of wedding invitations and event invitations, font design and typography, original hand-lettered logo design, religious art, announcements, graphic des ...
