Sienna Saveska
Sienna (from it, terra di Siena, meaning "Siena earth") is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown and is called raw sienna. When heated, it becomes a reddish brown and is called burnt sienna.''Shorter Oxford English Dictionary'', 5th Edition (2002) It takes its name from the city-state of Siena, where it was produced during the Renaissance. Along with ochre and umber, it was one of the first pigments to be used by humans, and is found in many cave paintings. Since the Renaissance, it has been one of the brown pigments most widely used by artists. The first recorded use of ''sienna'' as a color name in English was in 1760. The normalized color coordinates for sienna are identical to kobe, first recorded as a color name in English in 1924. Earth colors Like the other earth colors, such as yellow ochre and umber, sienna is a clay containing iron oxide, called limonite, which in its natural state has a y ...

Earth Pigment
Earth pigments are naturally occurring minerals containing metal oxides, principally iron oxides and manganese oxides, that have been used since prehistoric times as pigments. The primary types are ochre, sienna and umber. Earth pigments are known for their fast drying time in oil painting, relative inexpensiveness, and lightfastness. Cave paintings done in sienna still survive today. Production After mining, the mineral used for making a pigment is ground to a very fine powder (if not already in the form of clay), washed to remove water-soluble components, dried, and ground again to powder. For some pigments, notably sienna and umber, the color can be deepened by heating (calcination) in a process known as "burning", although it does not involve oxidation but instead dehydration In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arcidosso
Arcidosso is a ''comune'' (municipality) in the Province of Grosseto in the Italian region of Tuscany, located about south of Florence and about northeast of Grosseto and near the town of Montalcino. History The first certain documentation of the existence of the settlement of Arcidosso is from the year 860, when it is said to belong to the Abbey of San Salvatore. In 1331, Guidoriccio da Fogliano besieged it for four months with an army of 4,000 soldiers and 400 horsemen, until it surrendered. After the fall of the Republic of Siena in 1556, it passed under the Grand Duchy of Tuscany. Cosimo I de' Medici established many outlying offices here. Following the Leopoldina Reformation of 1786, there was a remarkable population increase and the number of Arcidosso's citizens quadrupled in about 100 years. Arcidosso thus became historically the most important political and administrative center in the Monte Amiata area. Geography ;Frazioni The municipality is formed by the municipal ...

Burnt Orange
In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light. Varieties of the color orange may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being an orange or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Orange (color wheel) The color known as ''color wheel orange'' is the tone of orange that is a pure chroma on the HSV color wheel, the expression of which is known as the RGB color wheel, ...

Palazzo Vecchio
The Palazzo Vecchio ( "Old Palace") is the City hall, town hall of Florence, Italy. It overlooks the Piazza della Signoria, which holds a copy of Michelangelo's ''David (Michelangelo), David'' statue, and the gallery of statues in the adjacent Loggia dei Lanzi. Originally called the ''Palazzo della Signoria'', after the Signoria of Florence, the ruling body of the Republic of Florence, this building was also known by several other names: ''Palazzo del Popolo'', ''Palazzo dei Priori'', and ''Palazzo Ducale'', in accordance with the varying use of the palace during its long history. The building acquired its current name when the Medici duke's residence was moved across the Arno River to the Palazzo Pitti. History In 1299, the commune and people of Florence decided to build a palace that would be worthy of the city's importance, and that would be more secure and defensible in times of turbulence for the magistrates of the commune.Bartlett, 37.

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Insular Italy
Insular Italy ( it, Italia insulare or just , meaning "islands") is one of the five official statistical regions of Italy used by the National Institute of Statistics (ISTAT), a first level NUTS region and a European Parliament constituency. Insular Italy encompasses two of the country's 20 regions: Sardinia and Sicily. Geography Insular Italy occupies one sixth of the national territory in surface area. Territorially, both Sicily and Sardinia include several minor islands and archipelagoes administratively dependent on the mother islands. Sicily is the largest island in the Mediterranean (25,708 km2) and one of the largest of Europe, while Sardinia is only slightly less extensive (24,090 km2). The lowlands are generally limited in the geographic region and generally appear as narrow coastal belts. The only exceptions are the Campidano and Nurra in Sardinia and the Plain of Catania in Sicily that extend 1200 km2 and 430 km2 respectively. The rest of the ...

Rembrandt
Rembrandt Harmenszoon van Rijn (, ; 15 July 1606 – 4 October 1669), usually simply known as Rembrandt, was a Dutch Golden Age painter, printmaker and draughtsman. An innovative and prolific master in three media, he is generally considered one of the greatest visual artists in the history of art and the most important in Dutch art history.Gombrich, p. 420. Unlike most Dutch masters of the 17th century, Rembrandt's works depict a wide range of style and subject matter, from portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological themes and animal studies. His contributions to art came in a period of great wealth and cultural achievement that historians call the Dutch Golden Age, when Dutch art (especially Dutch painting), whilst antithetical to the Baroque style that dominated Europe, was prolific and innovative. This era gave rise to important new genres. Like many artists of the Dutch Golden Age, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caravaggio
Michelangelo Merisi (Michele Angelo Merigi or Amerighi) da Caravaggio, known as simply Caravaggio (, , ; 29 September 1571 – 18 July 1610), was an Italian painter active in Rome for most of his artistic life. During the final four years of his life he moved between Naples, Malta, and Sicily until his death. His paintings have been characterized by art critics as combining a realistic observation of the human state, both physical and emotional, with a dramatic use of lighting, which had a formative influence on Baroque painting. Caravaggio employed close physical observation with a dramatic use of chiaroscuro that came to be known as tenebrism. He made the technique a dominant stylistic element, transfixing subjects in bright shafts of light and darkening shadows. Caravaggio vividly expressed crucial moments and scenes, often featuring violent struggles, torture, and death. He worked rapidly with live models, preferring to forgo drawings and work directly onto the canvas. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giorgio Vasari
Giorgio Vasari (, also , ; 30 July 1511 – 27 June 1574) was an Italian Renaissance Master, who worked as a painter, architect, engineer, writer, and historian, who is best known for his work ''The Lives of the Most Excellent Painters, Sculptors, and Architects'', considered the ideological foundation of all art-historical writing, and the basis for biographies of several Renaissance artists, including Leonardo da Vinci and Michelangelo. Vasari designed the ''Tomb of Michelangelo'' in the Basilica of Santa Croce, Florence that was completed in 1578. Based on Vasari's text in print about Giotto's new manner of painting as a ''rinascita'' (rebirth), author Jules Michelet in his ''Histoire de France'' (1835) suggested adoption of Vasari's concept, using the term ''Renaissance'' (rebirth, in French) to distinguish the cultural change. The term was adopted thereafter in historiography and still is in use today. Life Vasari was born prematurely on 30 July 1511 in Arezzo, Tuscany. ...
