Recessed Orders
A compound arch is an arch built using multiple independent sub-arches stacked vertically, with their arcs of voussoirs placed one on the top of the other. The goal of using a compound arch is usually to increase the overall strength and reliability (if only one order is fractured, the structure still stands). Each of these sub-arches, or "rings", of which the whole compound arch is composed, is called an arch order. In some compound orders their faces are in the same plane. But as a rule the orders are successively recessed, i.e. the innermost sub-arch, or order, is narrow, the next above it broader, the next is broader still, and so on. History This system of concentric arches was employed by the Romans early in the 6th century BC, in the Cloaca Maxima at Rome; three orders were used where the Cloaca enters the Tiber. In the Anglo-Saxon architecture the use dates at least to the late 8th century ( All Saints' Church, Brixworth with two concentric orders made of Roman bricks). T ...

Arles Amphitheatre
The Arles Amphitheatre (; ) is a Roman amphitheatre in Arles, southern France. Two-tiered, it is probably the most prominent tourist attraction in the city which thrived in ancient Rome. The towers jutting out from the top are medieval add-ons. Built in 90 AD, the amphitheatre held over 20,000 spectators of chariot races and bloody hand-to-hand battles. Nowadays, it draws smaller crowds for bullfighting during the Feria d'Arles, as well as plays and concerts in summer. In 1981, Arles Amphitheatre was listed as a UNESCO World Heritage Site, together with other Roman and medieval buildings of the city, as part of the Arles, Roman and Romanesque Monuments group. Building The building measures 136 m (446 ft) in length and 109 m (358 ft) wide, and features 120 arches. It has an oval arena surrounded by terraces, arcades on two levels (60 in all), bleachers, a system of galleries, drainage system in many corridors of access and staircases for a quick exit from ...

Compound Pier
Compound pier or cluster pier is the architectural term given to a clustered column or pier which consists of a centre mass or newel, to which engaged or semi-detached shafts have been attached, in order to perform (or to suggest the performance of) certain definite structural objects, such as to carry arches of additional orders, or to support the transverse or diagonal ribs of a vault, or the tie-beam of an important roof. In these cases, though performing different functions, the drums of the pier are often cut out of one stone. There are, however, cases where the shafts are detached from the pier and coupled to it by annulets at regular heights, as in the Early English period. Compound piers can often be found in Romanesque cathedrals of France and Norman architecture of England, including cathedrals of Durham, Winchester, Ely, and Peterborough. The Gothic evolution of the idea is frequently called a clustered column or cluster column. Pilier cantonné A pilier cantonn� ...

Rubble
Rubble is broken stone, of irregular size, shape and texture; undressed especially as a filling-in. Rubble naturally found in the soil is known also as 'brash' (compare cornbrash)."Rubble" def. 2., "Brash n. 2. def. 1. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) © Oxford University Press 2009 Where present, it becomes more noticeable when the land is ploughed or worked. Building " Rubble-work" is a name applied to several types of masonry. One kind, where the stones are loosely thrown together in a wall between boards and grouted with mortar almost like concrete, is called in Italian "muraglia di getto" and in French "bocage". In Pakistan, walls made of rubble and concrete, cast in a formwork, are called 'situ', which probably derives from Sanskrit (similar to the Latin 'in situ' meaning 'made on the spot'). Work executed with more or less large stones put together without any attempt at courses is called rubble walling. Where similar work is laid in ...

Ashlar
Ashlar () is a cut and dressed rock (geology), stone, worked using a chisel to achieve a specific form, typically rectangular in shape. The term can also refer to a structure built from such stones. Ashlar is the finest stone masonry unit, and is generally rectangular (cuboid). It was described by Vitruvius as ''opus isodomum'' or trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of requiring only very thin joints between blocks, and the visible face of the stone may be Quarry-faced stone, quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for simi ...

Gothic Architecture
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High Middle Ages, 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'' (); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the Classical architecture, architecture of classical antiquity. The defining design element of Gothic architecture is the Pointed arch (architecture), pointed 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 Basilica of Saint-Denis, Saint-Denis, near Paris, the choir was rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanesque Architecture
Romanesque architecture is an architectural style of medieval Europe that was predominant in the 11th and 12th centuries. The style eventually developed into the Gothic style with the shape of the arches providing a simple distinction: the Romanesque is characterized by semicircular arches, while the Gothic is marked by the pointed arches. The Romanesque emerged nearly simultaneously in multiple countries of Western Europe; its examples can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. Similarly to Gothic, the name of the style was transferred onto the contemporary Romanesque art. Combining features of ancient Roman and Byzantine buildings and other local traditions, Romanesque architecture is known by its massive quality, thick walls, round arches, sturdy pillars, barrel vaults, large towers and decorative arcading. Each building has clearly defined forms, frequently of very regular, symmetrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basilica Of Sant'Apollinare In Classe
The Basilica of Sant'Apollinare in Classe ("Saint Apollinaris in Classe") is a church in Classe, Ravenna, Italy, consecrated on 9 May 549 by the bishop Maximian and dedicated to Saint Apollinaris, the first bishop of Ravenna and Classe. An important monument of late Ancient Roman architecture, early church architecture and Byzantine art, in 1996 it was inscribed with seven other nearby monuments in the UNESCO World Heritage List, which described it as "an outstanding example of the early Christian basilica in its purity and simplicity of its design and use of space and in the sumptuous nature of its decoration". (See: Church architecture.) History Work on Sant'Apollinare in Classe started at the beginning of 6th century by order of Bishop Ursicinus, using money from the Roman banker Iulianus Argentarius. It was certainly located next to a Christian cemetery, and quite possibly on top of a pre-existing pagan one, as some of the ancient tombstones were re-used in its co ...
