Frescoes
Fresco ( or frescoes) is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting becomes an integral part of the wall. The word ''fresco'' () is derived from the Italian adjective ''fresco'' meaning "fresh", and may thus be contrasted with fresco-secco or secco mural painting techniques, which are applied to dried plaster, to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with Italian Renaissance painting. The word ''fresco'' is commonly and inaccurately used in English to refer to any wall painting regardless of the plaster technology or binding medium. This, in part, contributes to a misconception that the most geographically and temporally common wall painting technology was the painting into wet lime plaster. Even in apparently '' buon fresco'' technology, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giotto Di Bondone - No
Giotto di Bondone (; – January 8, 1337), known mononymously as Giotto, was an List of Italian painters, Italian painter and architect from Florence during the Late Middle Ages. He worked during the International Gothic, Gothic and Italian Renaissance painting#Proto-Renaissance painting, Proto-Renaissance period. Giotto's contemporary, the banker and chronicler Giovanni Villani, wrote that Giotto was "the most sovereign master of painting in his time, who drew all his figures and their postures according to nature" and of his publicly recognized "talent and excellence".Bartlett, Kenneth R. (1992). ''The Civilization of the Italian Renaissance''. Toronto: D.C. Heath and Company. (Paperback). p. 37. Giorgio Vasari described Giotto as making a decisive break from the prevalent Byzantine art, Byzantine style and as initiating "the great art of painting as we know it today, introducing the technique of drawing accurately from life, which had been neglected for more than two hundred ...

Basilica Of San Francesco D'Assisi
The Basilica of Saint Francis of Assisi (; ) is the mother church of the Roman Catholic Order of Friars Minor Conventual in Assisi, a town in the Umbria region in central Italy, where Francis of Assisi, Saint Francis was born and died. It is a papal minor basilica and one of the most important places of Christian pilgrimage in Italy. With its accompanying friary, Sacro Convento, the basilica is a distinctive landmark to those approaching Assisi. It has been a UNESCO World Heritage Site since 2000. The basilica, which was begun in 1228, is built into the side of a hill and comprises two churches (known as the Upper Church and the Lower Church) and a crypt, where the remains of the saint are interred. The interior of the Upper Church is an important early example of the Gothic architecture, Gothic style in Italy. The Upper and Lower Churches are decorated with frescoes by numerous Late Middle Ages, late medieval painters from the Roman and Tuscan schools, and include works by Cimabu ...

Italian Renaissance Painting
Italian Renaissance painting is the painting of the period beginning in the late 13th century and flourishing from the early 15th to late 16th centuries, occurring in the Italian Peninsula, which was at that time divided into many political states, some independent but others controlled by external powers. The painters of Renaissance Italy, although often attached to particular courts and with loyalties to particular towns, nonetheless wandered the length and breadth of Italy, often occupying a diplomatic status and disseminating artistic and philosophical ideas. The city of Florence in Tuscany is renowned as the birthplace of the Renaissance, and in particular of Renaissance painting, although later in the era Rome and Venice assumed increasing importance in painting. A detailed background is given in the companion articles Renaissance art and Renaissance architecture. Italian Renaissance painting is most often divided into four periods: the Proto-Renaissance (1300–1425), the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assisi
Assisi (, also ; ; from ; Central Italian: ''Ascesi'') is a town and comune of Italy in the Province of Perugia in the Umbria region, on the western flank of Monte Subasio. It is generally regarded as the birthplace of the Latin poet Propertius, born around 50–45 BC. It is the birthplace of St. Francis, who founded the Order of Friars Minor in that town in 1208, and of St. Clare of Assisi (''Chiara d'Offreducci''), who, with St. Francis, founded the Order of Poor Ladies, which later became the Order of Poor Clares after her death. The 19th-century St. Gabriel of Our Lady of Sorrows was also born in Assisi. History The earliest attested people of Assisi were the Umbri. In 77AD Pliny the Elder described Regio VI Umbria and said that the Umbri were thought to be the oldest inhabitants of Italy. The people of Assisi were mentioned by name. The Romans took control of central Italy after the Battle of Sentinum in 295 BC. They built the flourishing ''municipium'' As ...

Sinopia
Sinopia (also known as sinoper, named after the now Turkish city Sinop, Turkey, Sinop) is a dark reddish-brown natural earth pigment, whose reddish colour comes from hematite, a dehydrated form of iron oxide. It was widely used in Classical Antiquity and the Middle Ages for painting, and during the Renaissance art, Renaissance it was often used on the rough initial layer of plaster for the underdrawing for a fresco. The word came to be used both for the pigment and for the preparatory drawing itself, which may be revealed when a fresco is stripped from its wall for transfer. During the Middle Ages sinopia in Latin and Italian came to mean simply a red ochre. It entered the English language as the word sinoper, meaning a red earth colour. Sinopia is a colour in various modern colour systems. Sinopia pigment From Ancient times through the Renaissance, the pigment was mined in Cappadocia, and exported to Europe through the port of Sinop, Turkey, Sinop, a Greek colony on the B ...

Buon Fresco
is a fresco painting technique in which alkaline-resistant pigments, ground in water, are applied to wet plaster. It is distinguished from the fresco-secco (or ''a secco'') and finto fresco techniques, in which paints are applied to dried plaster. Description The buon fresco technique consists of painting with pigment ground in water on a thin layer of wet, fresh, lime mortar or plaster, for which the Italian word is intonaco. Because of the chemical makeup of the plaster, a binder is not required. However, some artists used lime as a binding medium for pigment to slow the drying process of the plaster and continue working for longer periods of time. After a number of hours the plaster reacts with the air in a process called carbonatation. This chemical reaction fixes the pigment particles at the plaster's surface in a protective crystalline mesh known as the lime crust. The advantage of buon fresco is its durability. In '' fresco-secco'', by contrast, the color does not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresco-secco
Fresco-secco (or a secco or fresco finto) is a wall painting technique where pigments mixed with an organic binder and/or lime are applied onto dry plaster. The paints used can e.g. be casein paint, tempera, oil paint, silicate mineral paint. If the pigments are mixed with lime water or lime milk and applied to a dry plaster the technique is called lime secco painting. The secco technique contrasts with the fresco technique, where the painting is executed on a layer of wet plaster. Because the pigments do not become part of the wall, as in buon fresco, fresco-secco paintings are less durable. The colors may flake off the painting as time goes by, but this technique has the advantages of a longer working time and retouchability. In Italy, the fresco technique was reintroduced around 1300 and led to an increase in the general quality of mural painting. This technological change coincided with the realistic turn in Western art and the changing liturgical use of murals. The tr ...

Carbonatation
Carbonatation is a chemical reaction in which calcium hydroxide reacts with carbon dioxide and forms insoluble calcium carbonate: :Ca(OH)2CO2->CaCO3H_2O The process of forming a carbonate is sometimes referred to as "carbonation", although this term usually refers to the process of dissolving carbon dioxide in water. Concrete Carbonatation is a slow process that occurs in concrete where lime ( CaO, or Ca(OH)2( aq)) in the cement reacts with carbon dioxide (CO2) from the air and forms calcium carbonate. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5. This highly alkaline environment is one in which the steel rebar is passivated and is protected from corrosion. According to the Pourbaix diagram for iron, the metal is passive when the pH is above 9.5.{{cite web , url=http://www.corrosion-doctors.org/Thermo/ironE-pH.htm , title=Pourbaix diagram of iron , publisher=Corrosion-doctors.org , date= , accessdate=2009- ...

Calcium Carbonate
Calcium carbonate is a chemical compound with the chemical formula . It is a common substance found in Rock (geology), rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls. Materials containing much calcium carbonate or resembling it are described as calcareous. Calcium carbonate is the active ingredient in agricultural lime and is produced when calcium ions in hard water react with carbonate ions to form limescale. It has medical use as a calcium supplement or as an antacid, but excessive consumption can be hazardous and cause hypercalcemia and digestive issues. Chemistry Calcium carbonate shares the typical properties of other carbonates. Notably, it: *reacts with acids, releasing carbonic acid which quickly disintegrates into carbon dioxide and water: : *releases carbon dioxide upon heating, called a thermal decomposition reaction, or calcination (to above 840 °C in the case of ), t ...

School Of Athens
A school is the educational institution (and, in the case of in-person learning, the building) designed to provide learning environments for the teaching of students, usually under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools that can be built and operated by both government and private organization. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
