Dry stone
–
Dry stone is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their construction method. Dry stone technology is best known in the context of wall construction, but dry stone artwork, buildings, bridges, Dry stone walls have been traditionally used in building construction as field boundaries and garden or churchyard walls, and on steep slopes as retaining walls for terracing. Some dry-stone wall constructions in north-west Europe have been dated back to the Neolithic Age, some Cornish hedges are believed by the Guild of Cornish Hedgers to date from 5000 BC, although there appears to be little dating evidence. In County Mayo, Ireland, a field system made from dry-stone walls. The cyclopean walls of the acropolis of Mycenae have been dated to 1350 BC, in Belize, the Mayan ruins at Lubaantun illustrate use of dry stone construction in architecture of the 8th and 9th centuries AD. When used as boundaries, dry stone structures often are known as dykes. Dry stone walls are characteristic of areas of Britain and Ireland where rock outcrops naturally or large stones exist in quantity in the soil. They are especially abundant in the West of Ireland, particularly Connemara and they may also be found throughout the Mediterranean, including retaining walls used for terracing. Such constructions are common where large stones are plentiful or conditions are too harsh for hedges capable of retaining livestock to be grown as field boundaries. Many thousands of miles of such walls exist, most of them centuries old, the technique of construction was brought to America primarily by English and Scots-Irish immigrants. The technique was taken to Australia and New Zealand. Similar walls also are found in the Swiss-Italian border region, where they are used to enclose the open space under large natural boulders or outcrops. The higher-lying rock-rich fields and pastures in Bohemias South-Western border range of Šumava are often lined by dry stone walls built of field-stones removed from the arable or cultural land and they serve both as cattle/sheep fences and the lots borders. Sometimes also the dry stone terracing is apparent, often combined with parts of masonry that are held together by a clay-cum-needles composite mortar. Great Zimbabwe is a city in the south-eastern hills of Zimbabwe, near Lake Mutirikwe. It was the capital of the Kingdom of Zimbabwe during the countrys Late Iron Age, construction on the monument began in the 11th century and continued until the 15th century. The exact identity of the Great Zimbabwe builders is at present unknown, the stone city spans an area of 722 hectares which, at its peak, could have housed up to 18,000 people

Inca Empire
–
The Inca Empire, also known as the Incan Empire and the Inka Empire, was the largest empire in pre-Columbian America, and possibly the largest empire in the world in the early 16th century. The administrative, political and military center of the empire was located in Cusco in modern-day Peru, the Inca civilization arose from the highlands of Peru sometime in the early 13th century. Its last stronghold was conquered by the Spanish in 1572, from 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. The Incas considered their king, the Sapa Inca, to be the son of the sun, the Inca Empire was unique in that it lacked many features associated with civilization in the Old world. In the words of one scholar, The Incas lacked the use of wheeled vehicles, the Incan economy has been described as feudal, slave, socialist. The economy functioned largely without money and without markets, instead, exchange of goods and services was based on reciprocity between individuals and among individuals, groups, and Inca rulers. Taxes consisted of an obligation of a person to the Empire. The Inca rulers reciprocated by granting access to land and goods and providing food, the Inca referred to their empire as Tawantinsuyu, the four suyu. The four suyu were, Chinchaysuyu, Antisuyu, Qullasuyu and Kuntisuyu, the name Tawantinsuyu was, therefore, a descriptive term indicating a union of provinces. The Spanish transliterated the name as Tahuatinsuyo or Tahuatinsuyu, the term Inka means ruler or lord in Quechua and was used to refer to the ruling class or the ruling family. The Incas were a small percentage of the total population of the empire, probably numbering only 15,000 to 40,000. The Spanish adopted the term as a term referring to all subjects of the empire rather than simply the ruling class. As such the name Imperio inca referred to the nation that they encountered, the Inca people were a pastoral tribe in the Cusco area around the 12th century. Incan oral history tells a story of three caves. The center cave at Tampu Tuqu was named Qhapaq Tuqu, the other caves were Maras Tuqu and Sutiq Tuqu. Four brothers and four sisters stepped out of the middle cave and they were, Ayar Manco, Ayar Cachi, Ayar Awqa and Ayar Uchu, and Mama Ocllo, Mama Raua, Mama Huaco and Mama Qura. Out of the side caves came the people who were to be the ancestors of all the Inca clans, Ayar Manco carried a magic staff made of the finest gold. Where this staff landed, the people would live and they traveled for a long time

Machu Picchu
–
Machu Picchu is a 15th-century Inca citadel situated on a mountain ridge 2,430 metres above sea level. It is located in the Cusco Region, Urubamba Province, Machupicchu District in Peru, above the Sacred Valley, most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti. Often mistakenly referred to as the Lost City of the Incas, the Incas built the estate around 1450 but abandoned it a century later at the time of the Spanish Conquest. Machu Picchu was built in the classical Inca style, with polished dry-stone walls and its three primary structures are the Inti Watana, the Temple of the Sun, and the Room of the Three Windows. Most of the buildings have been reconstructed in order to give tourists a better idea of how they originally appeared. By 1976, thirty percent of Machu Picchu had been restored, Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide Internet poll. In the Quechua language, machu means old or old person, while picchu means peak, mountain or prominence with a base that ends in sharp peaks. Machu Picchu was built around 1450, at the height of the Inca and its construction appears to date to the period of the two great Inca rulers, Pachacutec Inca Yupanqui and Túpac Inca Yupanqui. It was abandoned just over 100 years later, in 1572 and it is possible that most of its inhabitants died from smallpox introduced by travellers before the Spanish conquistadors arrived in the area. Although it was located only about 80 kilometers from the Inca capital in Cusco, the conquistadors had notes of a place called Piccho, although no record of a Spanish visit exists. The types of sacred rocks defaced by the conquistadors in other locations are untouched at Machu Picchu, over the centuries, the surrounding jungle overgrew the site, and few outside the immediate area knew of its existence. The site may have discovered and plundered in 1867 by a German businessman. Some evidence indicates that German engineer J. M. von Hassel arrived earlier, maps show references to Machu Picchu as early as 1874. In 1911 American historian and explorer Hiram Bingham travelled the region looking for the old Inca capital and was shown to Machu Picchu by a local farmer, Bingham brought Machu Picchu to international attention and organized another expedition in 1912 to undertake major clearing and excavation. He returned in 1914 and 1915 to continue with excavation, in 1981, Peru declared an area of 325.92 square kilometres surrounding Machu Picchu a Historical Sanctuary. In addition to the ruins, the sanctuary includes a portion of the adjoining region, rich with the flora and fauna of the Peruvian Yungas. In 1983, UNESCO designated Machu Picchu a World Heritage Site, describing it as a masterpiece of architecture

Henry Hobson Richardson
–
Henry Hobson Richardson was a prominent American architect who designed buildings in Albany, Boston, Buffalo, Chicago, Pittsburgh, Cincinnati, and other cities. The style he popularized is named for him, Richardsonian Romanesque, along with Louis Sullivan and Frank Lloyd Wright, Richardson is one of the recognized trinity of American architecture. He was the great-grandson of inventor and philosopher Joseph Priestley, who is credited with the discovery of oxygen. Richardson went on to study at Harvard College and Tulane University, initially, he was interested in civil engineering, but shifted to architecture, which led him to go to Paris in 1860 to attend the famed École des Beaux Arts in the atelier of Louis-Jules André. He didnt finish his training there, as family backing failed due to the U. S. Civil War, Richardson returned to the U. S. in 1865. He settled in New York in October 1865 and he found work with a builder, Charles, whom he had met in Paris. The two worked together but Richardson was not being challenged. He had little to do and yearned for more, Richardson developed a unique and highly personal idiom, adapting in particular the Romanesque of southern France. His early works, however, were not very remarkable, there are few hints in the mediocre work of Richardsons early years of what was to come in his maturity, when, beginning with his competition-winning design. For the Brattle Square Church in Boston, he adopted the Romanesque, in 1869, he designed the Buffalo State Asylum for the Insane in Buffalo, the largest commission of his career and the first appearance of his eponymous Richardsonian Romanesque style. A massive Medina sandstone complex, it is a National Historic Landmark and, the 1872 Trinity Church in Boston solidified Richardsons national reputation and led to major commissions for the rest of his life. Although incorporating historical elements from a variety of sources, including early Syrian Christian, Byzantine, Trinity was also a collaboration with the construction and engineering firm of the Norcross Brothers, with whom the architect would work on some 30 projects. Of his buildings, the two he liked best, the Allegheny County Courthouse and the Marshall Field Wholesale Store, were completed posthumously by his assistants, Richardson died in 1886 at age 47 of Brights disease, a historical term for the kidney disorder chronic nephritis. On his last day, he signed an informal will directing the three still remaining to carry on the business, which was soon formalized as Shepley, Rutan. One example includes Richardsons design for the Greater Cincinnati Chamber of Commerce Building, Richardson had won the selection process in 1885 and nearly finalized the work, but after his death, his aforementioned successors completed the project. He was buried in Walnut Hills Cemetery, Brookline, Massachusetts, despite an enormous income for an architect of his day, his reckless disregard for financial order meant that he died deeply in debt, leaving little to his widow and six children. Richardsons great grand-daughter is Mill Valley architect Heidi Richardson, Richardson spent much of his later years in his house in Brookline, Massachusetts, which had a studio attached to ease the strain on his health. The house fell into disrepair and was listed in 2007 as an historic site

Rock (geology)
–
Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a rock, is a combination of the minerals quartz, feldspar. The Earths outer solid layer, the lithosphere, is made of rock, rock has been used by mankind throughout history. The minerals and metals found in rocks have been essential to human civilization, three major groups of rocks are defined, igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is a component of geology. At a granular level, rocks are composed of grains of minerals, the aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed, many rocks contain silica, a compound of silicon and oxygen that forms 74. 3% of the Earths crust. This material forms crystals with other compounds in the rock, the proportion of silica in rocks and minerals is a major factor in determining their name and properties. Rocks are geologically classified according to such as mineral and chemical composition, permeability, the texture of the constituent particles. These physical properties are the end result of the processes that formed the rocks, over the course of time, rocks can transform from one type into another, as described by the geological model called the rock cycle. These events produce three general classes of rock, igneous, sedimentary, and metamorphic, the three classes of rocks are subdivided into many groups. However, there are no hard and fast boundaries between allied rocks, hence the definitions adopted in establishing rock nomenclature merely correspond to more or less arbitrary selected points in a continuously graduated series. Igneous rock forms through the cooling and solidification of magma or lava and this magma can be derived from partial melts of pre-existing rocks in either a planets mantle or crust. Typically, the melting of rocks is caused by one or more of three processes, an increase in temperature, a decrease in pressure, or a change in composition, igneous rocks are divided into two main categories, plutonic rock and volcanic. Plutonic or intrusive rocks result when magma cools and crystallizes slowly within the Earths crust, a common example of this type is granite. Volcanic or extrusive rocks result from magma reaching the surface either as lava or fragmental ejecta, the chemical abundance and the rate of cooling of magma typically forms a sequence known as Bowens reaction series. Most major igneous rocks are found along this scale, about 64. 7% of the Earths crust by volume consists of igneous rocks, making it the most plentiful category. Of these, 66% are basalts and gabbros, 16% are granite, only 0. 6% are syenites and 0. 3% peridotites and dunites

Masonry
–
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar, the term masonry can also refer to the units themselves. The common materials of construction are brick, building stone such as marble, granite, travertine, and limestone, cast stone, concrete block, glass block. Masonry is generally a durable form of construction. However, the used, the quality of the mortar and workmanship. A person who constructs masonry is called a mason or bricklayer, Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations, Concrete blocks, especially those with hollow cores, offer various possibilities in masonry construction. They generally provide great strength, and are best suited to structures with light transverse loading when the cores remain unfilled. Filling some or all of the cores with concrete or concrete with steel reinforcement offers much greater tensile, the use of material such as bricks and stones can increase the thermal mass of a building and can protect the building from fire. Masonry walls are resistant to projectiles, such as debris from hurricanes or tornadoes. Extreme weather, under circumstances, can cause degradation of masonry due to expansion. Masonry tends to be heavy and must be built upon a foundation, such as reinforced concrete. Other than concrete, masonry construction does not lend well to mechanization. Masonry consists of components and has a low tolerance to oscillation as compared to other materials such as reinforced concrete, plastics, wood. Masonry has high compressive strength under vertical loads but has low tensile strength unless reinforced, the tensile strength of masonry walls can be increased by thickening the wall, or by building masonry piers at intervals. Where practical, steel reinforcements such as windposts can be added, a masonry veneer wall consists of masonry units, usually clay-based bricks, installed on one or both sides of a structurally independent wall usually constructed of wood or masonry. In this context the brick masonry is primarily decorative, not structural, the brick veneer is generally connected to the structural wall by brick ties. There is typically an air gap between the veneer and the structural wall. Concrete blocks, real and cultured stones, and veneer adobe are sometimes used in a very similar veneer fashion

Vitruvius
–
His discussion of perfect proportion in architecture and the human body, led to the famous Renaissance drawing by Da Vinci of Vitruvian Man. By his own description Vitruvius served as an artilleryman, the class of arms in the military offices. He probably served as a officer of artillery in charge of doctores ballistarum. Little is known about Vitruvius life, most inferences about him are extracted from his only surviving work De Architectura. Even his first name Marcus and his cognomen Pollio are uncertain. Cetius Faventinus writes of Vitruvius Polio aliique auctores, this can be read as Vitruvius Polio, and others or, less likely, as Vitruvius, Polio, Vitruvius was a military engineer, or a praefect architectus armamentarius of the apparitor status group. He is mentioned in Pliny the Elders table of contents for Naturalis Historia, frontinus refers to Vitruvius the architect in his late 1st-century work De aquaeductu. Likely born a free Roman citizen, by his own account, Vitruvius served the Roman army under Caesar with the otherwise poorly identified Marcus Aurelius, Publius Minidius and these names vary depending on the edition of De architectura. Publius Minidius is also written as Publius Numidicus and Publius Numidius, as an army engineer he specialized in the construction of ballista and scorpio artillery war machines for sieges. It is speculated that Vitruvius served with Caesars chief engineer Lucius Cornelius Balbus, the locations where he served can be reconstructed from, for example, descriptions of the building methods of various foreign tribes. Although he describes places throughout De Architectura, he not say he was present. His service likely included north Africa, Hispania, Gaul and Pontus, the position of the camp, the direction of the entrenchments, the inspection of the tents or huts of the soldiers and the baggage were comprehended in his province. His authority extended over the sick, and the physicians who had the care of them and he had the charge of providing carriages, bathhouses and the proper tools for sawing and cutting wood, digging trenches, raising parapets, sinking wells and bringing water into the camp. He likewise had the care of furnishing the troops with wood and straw, as well as the rams, onagri, balistae, at various locations described by Vitruvius, battles and sieges occurred. He is the source for the siege of Larignum in 56 BC. The broken siege at Gergovia in 52 BC, and the siege of Uxellodunum in 51 BC. These are all sieges of large Gallic oppida, a legion that fits the same sequence of locations is the Legio VI Ferrata, of which ballista would be an auxiliary unit. Mainly known for his writings, Vitruvius was himself an architect, frontinus mentions him in connection with the standard sizes of pipes

Polygonal masonry
–
Polygonal masonry is a technique of stone construction. True polygonal masonry is a technique wherein the visible surfaces of the stones are dressed with straight sides or joints and this technique is found throughout the world and sometimes corresponds to the less technical category of Cyclopean masonry. Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina, the so-called Porta Rosa of the ancient city of Velia employs a variant of the technique known as Lesbian masonry.

Mortar (masonry)
–
In its broadest sense mortar includes pitch, asphalt, and soft mud or clay, such as used between mud bricks. Mortar comes from Latin mortarium meaning crushed, mortars are typically made from a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, there are several types of cement mortars and additives. The first mortars were made of mud and clay, because of a lack of stone and an abundance of clay, Babylonian constructions were of baked brick, using lime or pitch for mortar. According to Roman Ghirshman, the first evidence of using a form of mortar was at the Mehrgarh of Baluchistan in Pakistan. The ancient sites of Harappan civilization of third millennium BCE are built with kiln-fired bricks, gypsum mortar, also called plaster of Paris, was used in the construction of the Egyptian pyramids and many other ancient structures. It is made from gypsum, which requires a firing temperature. It is therefore easier to make lime mortar and sets up much faster which may be a reason it was used as the typical mortar in ancient, brick arch. Gypsum mortar is not as durable as other mortars in damp conditions, in early Egyptian pyramids, which were constructed during the Old Kingdom, the limestone blocks were bound by mortar of mud and clay, or clay and sand. In later Egyptian pyramids, the mortar was made of gypsum or lime. Gypsum mortar was essentially a mixture of plaster and sand and was quite soft, in the Indian subcontinent, multiple cement types have been observed in the sites of the Indus Valley Civilization, such as the Mohenjo-daro city-settlement that dates to earlier than 2600 BCE. Bitumen mortar was used at a lower-frequency, including in the Great Bath at Mohenjo-daro. Historically, building with concrete and mortar next appeared in Greece, the excavation of the underground aqueduct of Megara revealed that a reservoir was coated with a pozzolanic mortar 12 mm thick. This aqueduct dates back to c.500 BCE, pozzolanic mortar is a lime based mortar, but is made with an additive of volcanic ash that allows it to be hardened underwater, thus it is known as hydraulic cement. The Greeks obtained the volcanic ash from the Greek islands Thira and Nisiros, or from the then Greek colony of Dicaearchia near Naples, the Romans later improved the use and methods of making what became known as pozzolanic mortar and cement. Even later, the Romans used a mortar without pozzolana using crushed terra cotta, introducing aluminum oxide and this mortar was not as strong as pozzolanic mortar, but, because it was denser, it better resisted penetration by water. Hydraulic mortar was not available in ancient China, possibly due to a lack of volcanic ash, around 500 CE, sticky rice soup was mixed with slaked lime to make an inorganic−organic composite mortar that had more strength and water resistance than lime mortar. It is not understood how the art of making hydraulic mortar and cement, during the Middle Ages when the Gothic cathedrals were being built, the only active ingredient in the mortar was lime

Inca architecture
–
Incan architecture is the most significant pre-Columbian architecture in South America. The Incas inherited a legacy from Tiwanaku, founded in the 2nd century BCE in present-day Bolivia. The capital of the Inca empire, Cuzco, still contains many examples of Inca architecture. The famous royal estate of Machu Picchu is an example of Inca architecture. Other significant sites include Saksaywaman and Ollantaytambo, the Incas also developed an extensive road system spanning most of the western length of the continent. Inca buildings were made out of fieldstones or semi-worked stone blocks and dirt set in mortar, adobe walls were quite common. The material used in Inca buildings depended on the region, for instance, the most common shape in Inca architecture was the rectangular building without any internal walls and roofed with wooden beams and thatch. There were several variations of basic design, including gabled roofs. Rectangular buildings were used for different functions in almost all Inca buildings. Even so, there are examples of curved walls on Inca buildings. Two-story buildings were infrequent, when they were built the second floor was accessed from the outside via a stairway or high terrain rather than from the first floor. Wall apertures, including doors, niches and windows, usually had a trapezoidal shape, other kinds of decoration were scarce, some walls were painted or adorned with metal plaques, in rare cases walls were sculpted with small animals or geometric patterns. The most common form in Inca architecture was the kancha. A testimony of the importance of these compounds in Inca architecture is that the part of the Inca capital of Cusco consisted of large kancha, including Qurikancha. The best preserved examples of kancha are found at Ollantaytambo, an Inca settlement located along the Urubamba River, Inca architecture is widely known for its fine masonry, which features precisely cut and shaped stones closely fitted without mortar. However, despite this fame, most Inca buildings were made out of fieldstone. In the 1940s, American archaeologist John H. Rowe classified Inca fine masonry in two types, coursed, which features rectangular shaped stones, and polygonal, which blocks of irregular shape. In addition to references, they also identified some formal similarities between Tiwanaku and Inca architecture including the use of cut and polished stone blocks, as well as of double jambs

Brick
–
A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term referred to a unit composed of clay. A brick can be composed of clay-bearing soil, sand, and lime, Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are fired and non-fired bricks, block is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks are made from expanded clay aggregate, fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 5000 BC. Air-dried bricks, also known as mudbricks, have an older than fired bricks. Bricks are laid in courses and numerous patterns known as bonds, collectively known as brickwork, the earliest bricks were dried brick, meaning that they were formed from clay-bearing earth or mud and dried until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before 7500 BC, were found at Tell Aswad, in the upper Tigris region, ceramic, or fired brick was used as early as 3000 BC in early Indus Valley cities. In pre-modern China, bricks were being used from the 2nd millennium BCE at a site near Xian, the carpenters manual Yingzao Fashi, published in 1103 at the time of the Song dynasty described the brick making process and glazing techniques then in use. He also had to know when to quench the kiln with water so as to produce the surface glaze, Early civilisations around the Mediterranean adopted the use of fired bricks, including the Ancient Greeks and Romans. The Roman legions operated mobile kilns, and built large brick structures throughout the Roman Empire, during the Early Middle Ages the use of bricks in construction became popular in Northern Europe, after being introduced there from Northern-Western Italy. An independent style of architecture, known as brick Gothic flourished in places that lacked indigenous sources of rocks. Examples of this style can be found in modern-day Denmark, Germany, Poland. A clear distinction between the two styles developed at the transition to Baroque architecture. In Lübeck, for example, Brick Renaissance is clearly recognisable in buildings equipped with terracotta reliefs by the artist Statius von Düren, production of bricks increased massively with the onset of the Industrial Revolution and the rise in factory building in England. For reasons of speed and economy, bricks were increasingly preferred as building material to stone and it was at this time in London, that bright red brick was chosen for construction to make the buildings more visible in the heavy fog and to help prevent traffic accidents. The transition from the method of production known as hand-moulding to a mechanised form of mass-production slowly took place during the first half of the nineteenth century. His mechanical apparatus soon achieved widespread attention after it was adopted for use by the South Eastern Railway Company for brick-making at their factory near Folkestone, the Bradley & Craven Ltd ‘Stiff-Plastic Brickmaking Machine’ was patented in 1853, apparently predating Clayton

Classical architecture
–
Different styles of classical architecture have arguably existed since the Carolingian Renaissance, and prominently since the Italian Renaissance. Although classical styles of architecture can vary greatly, they can in all be said to draw on a common vocabulary of decorative and constructive elements. The term classical architecture also applies to any mode of architecture that has evolved to a highly refined state, such as classical Chinese architecture and it can also refer to any architecture that employs classical aesthetic philosophy. The term might be used differently from traditional or vernacular architecture, for contemporary buildings following authentic classical principles, the term New Classical Architecture may be used. Classical architecture is derived from the architecture of ancient Greece and ancient Rome, with the collapse of the western part of the Roman empire, the architectural traditions of the Roman empire ceased to be practised in large parts of western Europe. In the Byzantine Empire, the ancient ways of building lived on, the first conscious efforts to bring back the disused language of form of classical antiquity into Western architecture can be traced to the Carolingian Renaissance of the late 8th and 9th centuries. In general, therefore, they are not considered classical architectural styles in a strict sense, nonetheless, the classical architecture of the Renaissance from the outset represents a highly specific interpretation of the classical ideas. Most of the styles originating in post-renaissance Europe can be described as classical architecture and this broad use of the term is employed by Sir John Summerson in The Classical Language of Architecture. The elements of architecture have been applied in radically different architectural contexts than those for which they were developed. For example, Baroque or Rococo architecture are styles which, although classical at root, during these periods, architectural theory still referred to classical ideas but rather less sincerely than during the Renaissance. Neoclassical architecture held a strong position on the architectural scene c. With the advent of Modernism during the early 20th century, classical architecture arguably almost completely ceased to be practised, as noted above, classical styles of architecture dominated Western architecture for a very long time, roughly from the Renaissance until the advent of Modernism. That is to say, that classical antiquity at least in theory was considered the source of inspiration for architectural endeavours in the West for much of Modern history. Furthermore, it can even be argued that styles of architecture not typically considered classical, like Gothic, therefore, a simple delineation of the scope of classical architecture is difficult to make. The more or less defining characteristic can still be said to be a reference to ancient Greek or Roman architecture, and the architectural rules or theories that derived from that architecture. In the grammar of architecture, the word petrification is often used when discussing the development of sacred structures, such as temples, during the Archaic and early Classical periods, the architectural forms of the earliest temples had solidified and the Doric emerged as the predominant element. And not everyone within the reach of Mediterranean civilization made this transition. Nor was it the lack of knowledge of working on their part that prevented them from making the transition from timber to dressed stone
