Venetian Red
Venetian red is a light and warm (somewhat unsaturated) pigment that is a darker shade of red, derived from nearly pure ferric oxide (Fe2O3) of the hematite type. Modern versions are frequently made with synthetic red iron oxide. Historically, Venetian red was a red earth color often used in Italian Renaissance paintings. It was also called sinopia because the best-quality pigment came from the port of Sinop in northern Turkey. It was the major ingredient in the pigment called ', described by the 15th-century Italian painter and writer Cennino Cennini in his handbook on painting, ''Il libro dell'arte''. Cennini recommended mixing Venetian red with lime white, in proportions of two to one, to paint the skin tones of faces, hands and nudes. During the English Civil War (1642–1651), Venetian red was adopted as the primary uniform colour of the New Model Army, to ease mutual identification on the battlefield. In addition, Venetian red was cheaper than other dyes at the time. Follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shades Of Red
Varieties of the color red may differ in hue, colorfulness, 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 a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. In specific color systems Red (RGB) ''Red (RGB)'', ''RGB red'', or ''electric red'' (as opposed to ''pigment red'', shown below) is the brightest possible red that can be reproduced on a computer monitor. This color is an approximation of an orangish red spectral color. It is one of the three primary colors of light in the RGB color model, along with Shades of green#Computer web color greens, green and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a ...

Ferric Oxide
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide. Structure Fe2O3 can be obtained in various polymorphs. In the main one, α, iron adopts octahedral coordination geometry. That is, each Fe center is bound to six oxygen ligands. In the γ polymorph, some of the Fe sit on tetrahedral sites, with four oxygen ligands. Alpha phase α-Fe2O3 has the rhombohedral, corundum (α-Al2O3) structure and i ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Sinopia
Sinopia (also known as sinoper, named after the now Turkish city 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 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, a Greek colony on the Black Sea. The pigment was valued for its qualit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinop, Turkey
Sinop, historically known as Sinope (; gr, Σινώπη, Sinōpē), is a city on the isthmus of İnce Burun (İnceburun, Cape Ince), near Cape Sinope (Sinop Burnu, Boztepe Cape, Boztepe Burnu) which is situated on the northernmost edge of the Turkish side of the Black Sea coast, in the ancient region of Paphlagonia, in modern-day northern Turkey. The city serves as the capital of Sinop Province. History Over a period of approximately 2,500 years, Sinope has at various times been settled by Colchians, Greeks (in the late 7th, late 5th, and 4th–3rd centuries BC), by Romans in the mid-1st century BC, and by Turkic people beginning in the 12th century. In the 19th and 20th centuries it was also settled by the '' muhacir'' who immigrated from the Balkans and Caucasus. Evidence for Hittite Kingdom settlement along the Black Sea's southern shore remains murky. Researchers in the 1940s and 50s debated whether the "Great Sea", mentioned on the Boghazkoy tablets describing war b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cennino Cennini
Cennino d'Andrea Cennini (c. 1360 – before 1427) was an Italian painter influenced by Giotto. He was a student of Agnolo Gaddi in Florence. Gaddi trained under his father, called Taddeo Gaddi, who trained with Giotto. Cennini was born in Colle di Val d'Elsa, Tuscany. After training as an artist with Agnolo Gaddi in Florence he worked at the court of Francesco Novello da Carrara in Padua for some years before apparently returning to Colle di Val d'Elsa. He is remembered mainly for having authored ''Il libro dell'arte''. Thought to have been written around the turn of the 15th century, the book is a "how to" on late Medieval and early Renaissance painting. It contains information on pigments, brushes, drawing, panel painting, the art of fresco, painting on fabrics and casting, amongst other techniques and tricks. Cennini also mentions oil painting in passing, which was important for dispelling the myth, propagated by Giorgio Vasari and Karel Van Mander, that oil painting was ...

Lime (material)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

English Civil War
The English Civil War (1642–1651) was a series of civil wars and political machinations between Parliamentarians (" Roundheads") and Royalists led by Charles I ("Cavaliers"), mainly over the manner of England's governance and issues of religious freedom. It was part of the wider Wars of the Three Kingdoms. The first (1642–1646) and second (1648–1649) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (1649–1651) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The wars also involved the Scottish Covenanters and Irish Confederates. The war ended with Parliamentarian victory at the Battle of Worcester on 3 September 1651. Unlike other civil wars in England, which were mainly fought over who should rule, these conflicts were also concerned with how the three Kingdoms of England, Scotland and Ireland should be governed. The outcome was threefold: the trial of and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Model Army
The New Model Army was a standing army formed in 1645 by the Parliamentarians during the First English Civil War, then disbanded after the Stuart Restoration in 1660. It differed from other armies employed in the 1639 to 1653 Wars of the Three Kingdoms in that members were liable for service anywhere in the country, rather than being limited to a single area or garrison. To establish a professional officer corps, the army's leaders were prohibited from having seats in either the House of Lords or House of Commons. This was to encourage their separation from the political or religious factions among the Parliamentarians. The New Model Army was raised partly from among veteran soldiers who already had deeply held Puritan religious beliefs, and partly from conscripts who brought with them many commonly held beliefs about religion or society. Many of its common soldiers therefore held dissenting or radical views unique among English armies. Although the Army's senior officers d ...

British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Coat (military Uniform)
Red coat, also referred to as redcoat or scarlet tunic, was a military garment which was widely (though not exclusively) used by the infantry units of the British military, including the British Army and Royal Marines, from the 16th to 19th centuries. The garment was also widely used by the British Colonial Auxiliary Forces and the British Indian Army during the 18th and 19th centuries. Though by the 20th centuries the red coat was abandoned for practical duties in favour of khaki by all British and Commonwealth military units, it continues to be used for ceremonial full dress and mess dress uniforms. The usage of red coats by English soldiers dates back to the Tudor period, when the Yeomen of the Guard and the Yeomen Warders were both equipped in the royal colours of the House of Tudor, red and gold. During the Tudor conquest of Ireland and the Wars of the Three Kingdoms, units of English soldiers were equipped in red coats, most notably the New Model Army, which fought o ...
