Mural
–
A mural is any piece of artwork painted or applied directly on a wall, ceiling or other permanent surface. A distinguishing characteristic of painting is that the architectural elements of the given space are harmoniously incorporated into the picture. Some wall paintings are painted on canvases, which are then attached to the wall. Whether these works can be accurately called murals is a subject of controversy in the art world. Murals of sorts date to Upper Paleolithic times such as the paintings in the Chauvet Cave in Ardèche department of southern France, many ancient murals have been found within ancient Egyptian tombs, the Minoan palaces and in Pompeii. During the Middle Ages murals were executed on dry plaster. The huge collection of Kerala mural painting dating from the 14th century are examples of fresco secco, in Italy, circa 1300, the technique of painting of frescos on wet plaster was reintroduced and led to a significant increase in the quality of mural painting. In modern times, the became more well-known with the Mexican muralism art movement. There are many different styles and techniques, the best-known is probably fresco, which uses water-soluble paints with a damp lime wash, a rapid use of the resulting mixture over a large surface, and often in parts. The colors lighten as they dry, the marouflage method has also been used for millennia. Murals today are painted in a variety of ways, using oil or water-based media, the styles can vary from abstract to trompe-lœil. Initiated by the works of artists like Graham Rust or Rainer Maria Latzke in the 1980s, trompe-loeil painting has experienced a renaissance in private. The buon fresco technique consists of painting in pigment mixed with water on a layer of wet, fresh. The pigment is absorbed by the wet plaster, after a number of hours. After this the painting stays for a time up to centuries in fresh. Fresco-secco painting is done on dry plaster, the pigments thus require a binding medium, such as egg, glue or oil to attach the pigment to the wall. By the end of the century this had largely displaced the buon fresco method. This technique had, in reduced form, the advantages of a secco work, in Greco-Roman times, mostly encaustic colors applied in a cold state were used

Acrylic paint
–
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry, acrylic paint is typically used for crafting, or in art classes in schools because it does not require any chemicals, and rinses away with just water. It also is likely to leave a stain on clothes than oil paint. As early as 1934, the first usable acrylic resin dispersion was developed by German chemical company BASF, the synthetic paint was first used in the 1940s, combining some of the properties of oil and watercolor. Between 1946 and 1949, Leonard Bocour and Sam Golden invented a solution acrylic paint under the brand Magna paint, acrylics were made commercially available in the 1950s. Following that development, Golden came up with an acrylic paint called Aquatec. Otto Röhm invented acrylic resin, which was transformed into acrylic paint. These two product lines were the very first acrylic emulsion artists paints, water-based acrylic paints were subsequently sold as latex house paints, as latex is the technical term for a suspension of polymer microparticles in water. Interior latex house paints tend to be a combination of binder, filler, pigment, exterior latex house paints may also be a co-polymer blend, but the best exterior water-based paints are 100% acrylic, due to elasticity and other factors. Vinyl, however, costs half of what 100% acrylic resins cost, soon after the water-based acrylic binders were introduced as house paints, artists and companies alike began to explore the potential of the new binders. Water-soluble artists acrylic paints were sold commercially by Liquitex beginning in the 1950s, in 1963, Rowney was the first manufacturer to introduce artist’s acrylic paints in Europe, under the brand name Cryla. Before the 19th century, artists mixed their own paints, which allowed them to achieve the color and thickness. While suitable media and raw pigments are available for the production of acrylic paint, hand mixing may not be practical because of the fast drying time. Acrylic painters can modify the appearance, hardness, flexibility, texture, watercolor and oil painters also use various media, but the range of acrylic media is much greater. Acrylics have the ability to bond to many different surfaces, in these cases it is recommended that the surface first be sealed with an appropriate sealer. Acrylics can be applied in layers or washes to create effects that resemble watercolors. They can also be used to build layers of paint—gel and molding paste media are sometimes used to create paintings with relief features that are, quite literally. Acrylic paints are used in hobbies such as train, car, house

Stucco
–
Stucco or render is a material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a dense solid. It is used as coating for walls and ceilings and as a sculptural. Stucco may be used to cover less visually appealing construction materials such as metal, concrete, cinder block, or clay brick and adobe. In English, stucco usually means a coating for the outside of a building, and plaster one for interiors, as described below, but other European languages, importantly including Italian, do not have the same distinction, stucco means plaster in Italian and serves for both. This has led to English often using stucco for interior decorative plasterwork in relief, especially in art history, the difference in nomenclature between stucco, plaster, and mortar is based more on use than composition. Animal or plant fibers were often added for additional strength, in the latter nineteenth century, Portland cement was added with increasing frequency in an attempt to improve the durability of stucco. At the same time, traditional lime plasters were being replaced by gypsum plaster, traditional stucco is made of lime, sand, and water. Modern stucco is made of Portland cement, sand, and water, lime is added to increase the permeability and workability of modern stucco. Sometimes additives such as acrylics and glass fibers are added to improve the properties of the stucco. This is usually done with what is considered a one-coat stucco system, lime stucco is a relatively hard material that can be broken or chipped by hand without too much difficulty. The lime itself is white, color comes from the aggregate or any added pigments. Lime stucco has the property of being self-healing to a degree because of the slight water solubility of lime. Portland cement stucco is very hard and brittle and can easily crack if the base on which it is applied is not stable, typically its color was gray, from the innate color of most Portland cement, but white Portland cement is also used. Todays stucco manufacturers offer a wide range of colors that can be mixed integrally in the finish coat. As a building material, stucco is a durable, attractive and it was traditionally used as both an interior and exterior finish applied in one or two thin layers directly over a solid masonry, brick or stone surface. The finish coat usually contained a color and was typically textured for appearance. The lath added support for the wet plaster and tensile strength to the brittle, cured stucco, while the increased thickness, the traditional application of stucco and lath occurs in three coats — the scratch coat, the brown coat and the finish coat

Chile
–
Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about 1,250,000 square kilometres of Antarctica, the arid Atacama Desert in northern Chile contains great mineral wealth, principally copper. Southern Chile is rich in forests and grazing lands, and features a string of volcanoes and lakes, the southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands. Spain conquered and colonized Chile in the century, replacing Inca rule in northern and central Chile. After declaring its independence from Spain in 1818, Chile emerged in the 1830s as a relatively stable authoritarian republic, in the 1960s and 1970s the country experienced severe left-right political polarization and turmoil. The regime, headed by Augusto Pinochet, ended in 1990 after it lost a referendum in 1988 and was succeeded by a coalition which ruled through four presidencies until 2010. Chile is today one of South Americas most stable and prosperous nations and it leads Latin American nations in rankings of human development, competitiveness, income per capita, globalization, state of peace, economic freedom, and low perception of corruption. It also ranks high regionally in sustainability of the state, Chile is a founding member of the United Nations, the Union of South American Nations and the Community of Latin American and Caribbean States. There are various theories about the origin of the word Chile, another theory points to the similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili. Another origin attributed to chilli is the onomatopoeic cheele-cheele—the Mapuche imitation of the warble of a locally known as trile. The Spanish conquistadors heard about this name from the Incas, ultimately, Almagro is credited with the universalization of the name Chile, after naming the Mapocho valley as such. The older spelling Chili was in use in English until at least 1900 before switching over to Chile, stone tool evidence indicates humans sporadically frequented the Monte Verde valley area as long as 18,500 years ago. About 10,000 years ago, migrating Native Americans settled in fertile valleys, settlement sites from very early human habitation include Monte Verde, Cueva del Milodon and the Pali Aike Craters lava tube. They fought against the Sapa Inca Tupac Yupanqui and his army, the result of the bloody three-day confrontation known as the Battle of the Maule was that the Inca conquest of the territories of Chile ended at the Maule river. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors, the Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia, one of Francisco Pizarros lieutenants, who founded the city of Santiago on 12 February 1541. Although the Spanish did not find the gold and silver they sought, they recognized the agricultural potential of Chiles central valley

Pre-Columbian era
–
For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term used is Pre-Hispanic. Other civilizations were contemporary with the period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own written records, because many Christian Europeans of the time viewed such texts as heretical, men like Diego de Landa destroyed many texts in pyres, even while seeking to preserve native histories. Only a few documents have survived in their original languages, while others were transcribed or dictated into Spanish, giving modern historians glimpses of ancient culture. Indigenous American cultures continue to evolve after the pre-Columbian era, many of these peoples and their descendants continue traditional practices, while evolving and adapting new cultural practices and technologies into their lives. Now, the study of pre-Columbian cultures is most often based on scientific. Asian nomads are thought to have entered the Americas via the Bering Land Bridge, now the Bering Strait, genetic evidence found in Amerindians maternally inherited mitochondrial DNA supports the theory of multiple genetic populations migrating from Asia. Over the course of millennia, Paleo-Indians spread throughout North and South America, exactly when the first group of people migrated into the Americas is the subject of much debate. One of the earliest identifiable cultures was the Clovis culture, with sites dating from some 13,000 years ago, however, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate the colonization of the Americas dates from between 40,000 and 13,000 years ago, the chronology of migration models is currently divided into two general approaches. The first is the short chronology theory with the first movement beyond Alaska into the New World occurring no earlier than 14, 000–17,000 years ago, followed by successive waves of immigrants. The second belief is the long chronology theory, which proposes that the first group of people entered the hemisphere at an earlier date, possibly 50. In that case, the Eskimo peoples would have arrived separately and at a later date, probably no more than 2,000 years ago. The North American climate was unstable as the ice age receded and it finally stabilized by about 10,000 years ago, climatic conditions were then very similar to todays. Within this timeframe, roughly pertaining to the Archaic Period, numerous archaeological cultures have been identified, the unstable climate led to widespread migration, with early Paleo-Indians soon spreading throughout the Americas, diversifying into many hundreds of culturally distinct tribes. The paleo-indians were hunter-gatherers, likely characterized by small, mobile bands consisting of approximately 20 to 50 members of an extended family and these groups moved from place to place as preferred resources were depleted and new supplies were sought. During much of the Paleo-Indian period, bands are thought to have subsisted primarily through hunting now-extinct giant land animals such as mastodon, Paleo-Indian groups carried a variety of tools

Aztec religion
–
The Aztec religion is the Mesoamerican religion of the Aztecs. Like other Mesoamerican religions, it had elements of human sacrifice in connection with a number of religious festivals which were held according to patterns of the Aztec calendar. Aztec cosmology divides the world into thirteen heavens and nine earthly layers or netherworlds each level associated with a set of deities. The concept of Teotl is central to the Aztecs, the term is often translated as god, but may have held more abstract aspects of divinity or supernatural energy akin to the Polynesian concept of Mana. The many gods of the Aztecs can be grouped into complexes related to different themes, other deities, for example Tezcatlipoca and Quetzalcoatl, had roots in earlier civilizations of Mesoamerica and were worshiped by many cultures and by many names. Some gods embodied aspects of nature, a large group of gods were related to pulque, drunkenness, excess, fun and games. Other gods were associated with specific trades, many gods had multiple aspects with different names, where each name highlighted a specific function or trait of the god. Occasionally, two gods were conflated into one, and quite often deities transformed into one another within a single story. Aztec images sometimes combined attributes of several divinities, nicholson classed the gods into three groups according to their conceptual meaning in general Mesoamerican religion. The first group he calls the Celestial creativity – Divine Paternalism group, the second, the earth-mother gods, the third group, the War-Sacrifice-Sanguinary Nourishment group contained such gods as Ome Tochtli, Huitzilopochtli, Mictlantecutli and Mixcoatl. Instead of Nicholsons subtle classification in the following a more impressionist classification is presented, on the state level, religion was controlled by the Tlatoani and the high priests governing the main temples in the ceremonial precinct of the Aztec capital of Tenochtitlan. For example, on the feast of Huey Tozoztli, the ruler himself ascended Mt. Tlaloc, throughout society, each level had their own rituals and deities and played their part in the larger rituals of the community. On the feast of Ochpaniztli, all participated in sweeping the streets. Huixachtlan, lit on the chest of a person by the high priests. The Tlatoani of Tenochtitlan was the head of the cult of Huitzilopochtli and he had special priestly duties in different rituals on the state level. However, the Aztec religious organization was not entirely under his authority, under these religious heads were many tiers of priests, priestesses, novices, nuns and monks who ran the cults of the various gods and goddesses. Sahagun reports that the priests had a strict training, and had to live very austere and ethical lives involving prolonged vigils, fasts. For instance, they often had to bleed themselves and undertake prescribed self-mortifications in the buildup to sacrificial rites, additionally, Sahagun refers to classes of religious specialists not affiliated with the established priesthood

Tlaloc
–
For the fictional character from the Legends of Dune books, see Titan #Tlaloc. Tlaloc was part of the pantheon of gods in Aztec religion, as supreme god of the rain, Tlaloc was also by extension a god of earthly fertility and of water. Tlaloc is also associated with caves, springs, and mountains and his animal forms include herons and water-dwelling creatures such as amphibians, snails, and possibly sea creatures, particularly shellfish. The Mexican marigold, Tagetes lucida, known to the Aztecs as yauhtli, was another important symbol of the god, the cult of Tlaloc is one of the oldest and most universal in ancient Mexico. An underground Tlaloc shrine has been found at Teotihuacan, in Aztec cosmology, the four corners of the universe are marked by the four Tlalocs which both hold up the sky and function as the frame for the passing of time. Tlaloc was the patron of the Calendar day Mazātl, in Aztec mythology, Tlaloc was the lord of the third sun which was destroyed by fire. Additionally, Tlaloc is thought to be one of the deities of the trecena of 1 Quiahuitl. Trecenas are the thirteen-day periods into which the 260-day calendar is divided, the first day of each trecena dictates the augury, or omen, and the patron deity or deities associated with the trecena. In the Aztec capital Tenochtitlan, one of the two shrines on top of the Great Temple was dedicated to Tlaloc, the high priest who was in charge of the Tlaloc shrine was called Quetzalcoatl Tlaloc Tlamacazqui. It was the northernmost side of temple that was dedicated to Tlaloc. In this area, a bowl was kept in which sacrificial hearts placed on certain occasions, here the Aztec ruler came and conducted important ceremonies once a year, and throughout the year pilgrims offered precious stones and figures at the shrine. Many of the offerings found here also related to water and the sea, in Aztec iconography, Tlaloc is usually depicted with goggle eyes and fangs. He is most often coupled with lightning, maize, and water in visual representations and this differs from the Maya version of Tlaloc, however, as the Maya version shows no specific relation to jaguars. The inhabitants of Teotihuacan thought of thunder as the rumblings of the jaguar and it is likely that this god was given these associations because he is also known as the provider among the Aztecs. Offerings dedicated to Tlaloc in Tenochtitlan were known to include several jaguar skulls, jaguars were considered the ultimate sacrificial animal due to their value. Tlalocs impersonators often wore the mask and heron-feather headdress, usually carrying a cornstalk or a symbolic lightning bolt wand. Along with this, Tlaloc is manifested in the form of boulders at shrine-sites, in Coatlinchan, a colossal statue weighing 168 tons was found that was thought to represent Tlaloc. However, one believes that the statue may not have been Tlaloc at all

Quetzalcoatl
–
Quetzalcoatl forms part of Mesoamerican literature and is a deity whose name comes from the Nahuatl language and means feathered serpent. The worship of a serpent is first documented in Teotihuacan in the first century BC or first century AD. That period lies within the Late Preclassic to Early Classic period of Mesoamerican chronology, in the Postclassic period, the worship of the feathered serpent deity was based in the primary Mexican religious center of Cholula. It is in period that the deity is known to have been named Quetzalcoatl by his Nahua followers. In the Maya area, he was approximately equivalent to Kukulkan and Gukumatz, Quetzalcoatl, the Aztec god of wind and learning, wears around his neck the wind breastplate ehecailacocozcatl, the spirally voluted wind jewel made of a conch shell. In codex drawings, Quetzalcoatl and Xolotl were both pictured as wearing an ehecailacocozcatl around each of their necks. There has additionally been at least one major cache of offerings with knives and idols adorned with the symbols of more than one god, some of which were adorned with wind jewels. It is a matter of debate among historians to which degree, or whether at all. He was also the god of the Aztec priesthood, of learning. Quetzalcoatl was one of several important gods in the Aztec pantheon, along with the gods Tlaloc, Tezcatlipoca, two other gods represented by the planet Venus are Quetzalcoatls ally Tlaloc who is the god of rain, and Quetzalcoatls twin and psychopomp, who is named Xolotl. Animals thought to represent Quetzalcoatl include resplendent quetzals, rattlesnakes, crows, in his form as Ehecatl he is the wind, and is represented by spider monkeys, ducks, and the wind itself. In his form as the star, Venus, he is also depicted as a harpy eagle. In Mazatec legends, the astrologer deity Tlahuizcalpantecuhtli, who is represented by Venus. A feathered serpent deity has been worshiped by many different ethno-political groups in Mesoamerican history, the existence of such worship can be seen through studies of iconography of different Mesoamerican cultures, in which serpent motifs are frequent. This depiction is believed to have made around 900 BC. The first culture to use the symbol of a serpent as an important religious. At temples such as the aptly named Quetzalcoatl temple in the Ciudadela complex, feathered serpents figure prominently, the earliest depictions of the feathered serpent deity were fully zoomorphic, depicting the serpent as an actual snake, but already among the Classic Maya the deity began acquiring human features. Feathered serpent iconography is prominent at all of these sites, Cholula is known to have remained the most important center of worship to Quetzalcoatl, the Aztec/Nahua version of the feathered serpent deity, in the post-classic period

Maize
–
Maize, also known as corn, is a large grain plant first domesticated by indigenous peoples in Mexico about 10,000 years ago. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, the leafy stalk of the plant produces separate pollen and ovuliferous inflorescences or ears, which are fruits, yielding kernels or seeds. Maize kernels are used in cooking as a starch. Most historians believe maize was domesticated in the Tehuacan Valley of Mexico, recent research modified this view somewhat, scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication. The Olmec and Mayans cultivated maize in numerous varieties throughout Mesoamerica, cooked and its believed that beginning about 2500 BC, the crop spread through much of the Americas. The region developed a network based on surplus and varieties of maize crops. Nevertheless, recent data indicates that the spread of maize took place even earlier, according to Piperno, A large corpus of data indicates that it was dispersed into lower Central America by 7600 BP and had moved into the inter-Andean valleys of Colombia between 7000 and 6000 BP. Since then, even earlier dates have been published, the study also demonstrated that the oldest surviving maize types are those of the Mexican highlands. Later, maize spread from this region over the Americas along two major paths and this is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands. Before they were domesticated, maize plants only grew small,25 millimetres long corn cobs, Maize is the most widely grown grain crop throughout the Americas, with 361 million metric tons grown in the United States in 2014. Approximately 40% of the crop—130 million tons—is used for corn ethanol, genetically modified maize made up 85% of the maize planted in the United States in 2009. After the arrival of Europeans in 1492, Spanish settlers consumed maize and explorers and traders carried it back to Europe, Spanish settlers far preferred wheat bread to maize, cassava, or potatoes. Maize flour could not be substituted for wheat for bread, since in Christian belief only wheat could undergo transubstantiation. At another level, Spaniards worried that by eating indigenous foods, which they did not consider nutritious, that not only would they weaken, despite these worries, Spaniards did consume maize and archeological evidence from Florida sites indicate they cultivated it as well. Maize spread to the rest of the world because of its ability to grow in diverse climates and it was cultivated in Spain just a few decades after Columbuss voyages and then spread to Italy, West Africa and elsewhere. The word maize derives from the Spanish form of the indigenous Taíno word for the plant and it is known by other names around the world. The word corn outside North America, Australia, and New Zealand refers to any cereal crop, in the United States, Canada, Australia, and New Zealand, corn primarily means maize, this usage started as a shortening of Indian corn. Indian corn primarily means maize, but can more specifically to multicolored flint corn used for decoration

Wheat
–
Wheat is a cereal grain, originally from the Levant region but now cultivated worldwide. In 2016, world production of wheat was 749 million tonnes, making it the second most-produced cereal after maize, since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st Century. This grain is grown on land area than any other commercial food. World trade in wheat is greater than for all other crops combined, globally, wheat is the leading source of vegetal protein in human food, having a protein content of about 13%, which is relatively high compared to other major cereals and staple foods. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. In a small part of the population, gluten – the major part of wheat protein – can trigger coeliac disease, non-coeliac gluten sensitivity, gluten ataxia. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the creation of domestic strains, in domesticated wheat, grains are larger, and the seeds remain attached to the ear by a toughened rachis during harvesting. In wild strains, a more fragile rachis allows the ear to easily shatter, as the traits that improve wheat as a food source also involve the loss of the plants natural seed dispersal mechanisms, highly domesticated strains of wheat cannot survive in the wild. Cultivation of wheat began to spread beyond the Fertile Crescent after about 8000 BCE, jared Diamond traces the spread of cultivated emmer wheat starting in the Fertile Crescent sometime before 8800 BCE. Archaeological analysis of wild emmer indicates that it was first cultivated in the southern Levant with finds dating back as far as 9600 BCE, Genetic analysis of wild einkorn wheat suggests that it was first grown in the Karacadag Mountains in southeastern Turkey. Dated archeological remains of wheat in settlement sites near this region, including those at Abu Hureyra in Syria. With the anomalous exception of two grains from Iraq ed-Dubb, the earliest carbon-14 date for einkorn wheat remains at Abu Hureyra is 7800 to 7500 years BCE. Remains of harvested emmer from several sites near the Karacadag Range have been dated to between 8600 and 8400 BCE, that is, in the Neolithic period and these remains were dated by Willem van Zeist and his assistant Johanna Bakker-Heeres to 8800 BCE. They also concluded that the settlers of Tell Aswad did not develop this form of emmer themselves, the cultivation of emmer reached Greece, Cyprus and India by 6500 BCE, Egypt shortly after 6000 BCE, and Germany and Spain by 5000 BCE. The early Egyptians were developers of bread and the use of the oven, by 3000 BCE, wheat had reached the British Isles and Scandinavia. A millennium later it reached China, the oldest evidence for hexaploid wheat has been confirmed through DNA analysis of wheat seeds, dating to around 6400-6200 BCE, recovered from Çatalhöyük. The first identifiable bread wheat with sufficient gluten for yeasted breads has been identified using DNA analysis in samples from a dating to approximately 1350 BCE at Assiros in Macedonia. From Asia, wheat continued to spread throughout Europe, in the British Isles, wheat straw was used for roofing in the Bronze Age, and was in common use until the late 19th century

Capital (architecture)
–
In architecture the capital or chapiter forms the topmost member of a column. It mediates between the column and the load thrusting down upon it, broadening the area of the supporting surface. The capital, projecting on each side as it rises to support the abacus, joins the usually square abacus and the usually circular shaft of the column. The capital may be convex, as in the Doric order, concave, as in the bell of the Corinthian order, or scrolling out. These form the three types on which all capitals are based. The Composite order, established in the 16th century on a hint from the Arch of Titus, from the highly visible position it occupies in all colonnaded monumental buildings, the capital is often selected for ornamentation, and is often the clearest indicator of the architectural order. The treatment of its detail may be an indication of the buildings date, the decoration underneath the bracket capital comes from art and designs from the many cultures that the Persian Empire conquered and assimilated including Egypt, Babylon, and Lydia. But of course these decorations below the bracket capital serve no purpose and are simply there for show. The earliest Aegean capital is shown in the frescoes at Knossos in Crete, it was of the convex type. The Doric capital is the simplest of the five Classical orders, it consists of the abacus above an ovolo molding, the sloping side of the echinus becomes flatter in the later examples, and in the Colosseum at Rome forms a quarter round. In the Ionic capital, spirally coiled volutes are inserted between the abacus and the ovolo. In the Ionic capitals of the archaic Temple of Artemis at Ephesus the width of the abacus is twice that of its depth, a century later, in the temple on the Ilissus, the abacus has become square. It has been suggested that the foliage of the Greek Corinthian capital was based on the Acanthus spinosus, not all architectural foliage is as realistic as Isaac Wares however. The leaves are carved in two ranks or bands, like one leafy cup set within another. The various orders are discussed in Vitruvius books iii and iv, Vitruvius describes Roman practice in a practical fashion. He gives some tales about the invention of each of the Orders, the increasing adoption of composite capitals signalled a trend towards freer, more inventive capitals in Late Antiquity. The top of an anta is often decorated, usually with bands of floral motifs. The designs often respond to an order of columns, but usually with a different set of design principles, in order not to protude excessively from the wall surface, these structures tend to have a rather flat surface, forming brick-shaped capitals, called anta capitals

Opuntia
–
Opuntia is a genus in the cactus family, Cactaceae. The most common species is the Indian fig opuntia. Most culinary uses of the prickly pear refer to this species. Prickly pears are also known as tuna, sabra, nopal from the Nahuatl word nōpalli for the pads, or nostle, from the Nahuatl word nōchtli for the fruit, or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, like all true cactus species, prickly pears are native only to the Americas, but they have been introduced to other parts of the globe. Prickly pear species are found in abundance in Mexico, especially in the central and western regions, Prickly pear cactus is also native to coastal beach scrub environments and low open areas of the East Coast from Florida to Connecticut/Long Island. Prickly pears also produce a fruit, commonly eaten in Mexico and in the Mediterranean region, known as tuna, the fruit can be red, wine-red, green, or yellow-orange. The first introduction of prickly pears into Australia is ascribed to Governor Philip, brought from Brazil to Sydney, prickly pear grew in Sydney, New South Wales, where they were rediscovered in a farmers garden in 1839. They appear to have spread from New South Wales and caused great damage in the eastern states. In the Galápagos Islands, six different species are found, O. echios, O. galapageia, O. helleri, O. insularis, O. saxicola and these species are divided into 14 different varieties, most of these are confined to one or a few islands. For this reason, they have described as an excellent example of adaptive radiation. On the whole, islands with tall, trunked varieties have giant tortoises, Prickly pears are a prime source of food for the common giant tortoises in the Galápagos islands so they are important in the food web. Charles Darwin was the first to note that these cacti have thigmotactic anthers and this movement can be seen by gently poking the anthers of an open Opuntia flower. The same trait has evolved convergently in other cacti, chollas, now recognized to belong to the distinct genus Cylindropuntia, are distinguished by having cylindrical, rather than flattened, stem segments with large barbed spines. The barbed spines can remain embedded in the skin, causing discomfort, collectively, opuntias, chollas, and related plants are sometimes called opuntiads. When Carl Linnaeus published Species Plantarum in 1753 – the starting point for botanical nomenclature – he placed all the species of cactus known to him in one genus, Cactus. In 1754, the Scottish botanist Philip Miller divided cacti into several genera and he distinguished the genus largely on the form of its flowers and fruits. Also, not all species listed here may actually belong in this genus, – quipá Opuntia insularis Opuntia invicta syn. O. leptocarpa MacKensen, O. tenuispina Engelm
