Frieze
In architecture, the frieze is the wide central section part of an entablature and may be plain in the Ionic or Doric order, 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. This style is typical for the Persians. 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 of may be plasterwork, carved wood or other decorative medium. ...

Parthenon Frieze
The Parthenon frieze is the high-relief Pentelic marble sculpture created to adorn the upper part of the Parthenon’s naos. It was sculpted between c. 443 and 437 BC, most likely under the direction of Pheidias. 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 Venetian bombardment that ruined the temple. At present, the majority of the frieze is at the British Museum in London (forming the major part of the Elgin Marbles); the largest proportion of the rest is at the Acropolis Museum in Athens, and the remainder of fragments shared between six other institutions. Casts of the frieze may be found in the Beazley archive at the Ashmolean Museum at Oxford, at the Spurlock Museum in Urbana, in the Skulpturhalle at Basel and elsewhere.

Frieze Pattern
In mathematics, a frieze or frieze pattern is a two-dimensional design that repeats in one direction. Such patterns occur frequently in architecture and decorative art. Frieze patterns can be classified into seven types according to their symmetries. The set of 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. General Formally, a frieze group is a class of infinite discrete symmetry groups of patterns on a strip (infinitely wide rectangle), hence a class of groups of isometries of the plane, or of a strip. A symmetry group of a frieze group necessarily contains translations and may contain glide reflections, reflections along the long axis of the strip, reflections along the n ...

Bas-relief
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires a lot of chiselling away of the background, which takes a long time. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs ...

Erechtheum
The Erechtheion (latinized as Erechtheum /ɪˈrɛkθiəm, ˌɛrɪkˈθiːəm/; Ancient Greek: Ἐρέχθειον, Greek: Ερέχθειο) or Temple of Athena Polias is an ancient Greek Ionic temple-telesterion on the north side of the Acropolis, Athens, which was primarily dedicated to the goddess Athena. The building, made to house the statue of Athena Polias, has in modern scholarship been called the Erechtheion (the sanctuary of Erechtheus or Poseidon) in the belief that Pausanias' description of the Erechtheion applies to this building. However, whether the Erechtheion referred to by Pausanias is indeed the Ionic temple or an entirely different building has become a point of contention in recent decades. In the official decrees the building is referred to as “... το͂ νεὸ το͂ ἐμ πόλει ἐν ο͂ι τὸ ἀρχαῖον ἄγαλμα” (the temple on the Acropolis within which is the ancient statue). In other instances it is referred to as the Temple o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sculpture
Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramic art, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or Molding (process), moulded or Casting, cast. Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. However, most ancient sculpture was brightly painted, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Architecture
Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements. The practice, which began in the prehistoric era, has been used as a way of expressing culture for civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century AD treatise '' De architectura'' by the Roman architect Vitruvius, according to whom a good building embodies , and (durability, utility, and beauty). ...

Painting
Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term ''painting ''describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate multiple other materials, including sand, clay, paper, plaster, gold leaf, and even whole objects. Painting is an important form in the visual arts, bringing in elements such as drawing, composition, gesture (as in gestural painting), narration (as in narrative art), and abstraction (as in abstract art). Paintings can be naturalistic and representational (as in still life and landscape painting), photographic, abstract, nar ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

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.
