Sienna Nanini
Sienna () is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown, and it is called raw sienna. When heated, it becomes a reddish brown, and it 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 which is partially composed of iron oxides. In the case of sienna, the most prevalent iron oxides are limonite (which in it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Pigment
Earth pigments are naturally occurring minerals that have been used since prehistoric times as pigments. Among the primary types of earth pigments include the reddish-brown ochres, siennas, and umbers, which contain various amounts of iron oxides and manganese oxides. p. 30 Other earth pigments include the green earth pigments or , blue earth pigments such as vivianite-based "blue ochre", white earth pigments such as chalk, and black earth pigments such as charcoal. 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 d ...

Limonite
Limonite () is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as , although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mining, mined for the production of iron since at least 400 BC. Names Limonite is named for the Ancient Greek word ( ), meaning "wet meadow", or ( ), meaning "marshy lake", as an allusion to its occurrence as in meadows and marshes. In its brown form, it is sometimes called brown hematite or brown iron ore. Characteristics Limonite is relatively density, dense with a specific gravity varying from 2.7 to 4.3.Northrop, Stuart A. (1959) "Limonite" ''Minerals of New Mexico'' (revised edition) University of New Mexico Press, Albuquerque, New Mexico, pp. 329–333, It is usually medium to dark yellowish brown in color. T ...

During the final four years of his life, he moved between Kingdom of Naples, Naples, Hospitaller Malta, Malta, and Kingdom of Sicily, Sicily. 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, preferrin ...

Giorgio Vasari
Giorgio Vasari (30 July 1511 – 27 June 1574) was an Italian Renaissance painter, architect, art historian, and biographer who is best known for his work ''Lives of the Most Excellent Painters, Sculptors, and Architects'', considered the ideological foundation of Western art history, art-historical writing, and still much cited in modern biographies of the many Italian Renaissance artists he covers, including Leonardo da Vinci and Michelangelo, although he is now regarded as including many factual errors, especially when covering artists from before he was born. Vasari was a Mannerist painter who was highly regarded both as a painter and architect in his day but rather less so in later centuries. He was effectively what would now be called the minister of culture to the Medici court in Florence, and the ''Lives'' promoted, with enduring success, the idea of Florentine superiority in the visual arts. Vasari designed the ''Tomb of Michelangelo'', his hero, in the Santa Croce, Fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monte Amiata
Mount Amiata is the largest of the lava domes in the Amiata lava dome complex located about 20 km northwest of Lake Bolsena in the southern Tuscany region of Italy. It is located within the provinces of Grosseto and Siena. Geology Mount Amiata (La Vetta) is a compound lava dome with a trachytic lava flow that extends to the east. It is part of the larger Amiata complex volcano. A massive viscous trachydacitic lava flow, 5 km long and 4 km wide, is part of the basal complex and extends from beneath the southern base of the Corno de Bellaria dome. Radiometric dates indicate that the Amiata complex had a major eruptive episode about 300,000 years ago. No eruptive activity has occurred at Amiata during the Holocene, but thermal activity including cinnabar mineralization continues at a geothermal field near the town of Bagnore, at the SW end of the dome complex. Economy The main economical resources of the Amiata region are chestnuts, timber and, increasingly, tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
