Barbute MET DP-12880-047
A barbute (also termed a barbuta, which in Italian literally means "bearded", possibly because the beard of a wearer would be visible) is a visorless war helmet of 15th-century Italian design, often with a distinctive "T" shaped or "Y" shaped opening for the eyes and mouth. Origins The name 'barbuta' when applied to a helmet is first recorded in an inventory made for the Gonzaga family of Mantua in 1407. The helmet can be considered as a specialised form of the sallet, both types of helmet being ultimately derivations of the earlier bascinet. The barbute resembles classical Greek helmets (most strikingly the Corinthian) and may have been influenced by the renewed interest in ancient artifacts common during this period. Characteristics This type of helmet has been described as an example of formal beauty being the result of functional efficiency. The defining characteristic of the barbute is the forward extension of the sides of the helmet towards the mid-line; this gives prot ...

Gorget
A gorget , from the French ' meaning throat, was a band of linen wrapped around a woman's neck and head in the medieval period or the lower part of a simple chaperon hood. The term later described a steel or leather collar to protect the throat, a set of pieces of plate armour, or a single piece of plate armour hanging from the neck and covering the throat and chest. Later, particularly from the 18th century, the gorget became primarily ornamental, serving as a symbolic accessory on military uniforms, a use which has survived in some armies. The term may also be used for other things such as items of jewellery worn around the throat region in several societies, for example wide thin gold collars found in prehistoric Ireland dating to the Bronze Age. As part of armour In the High Middle Ages, when mail was the primary form of metal body armour used in Western Europe, the mail coif protected the neck and lower face. As more plate armour appeared to supplement mail during the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quenched
In materials science, quenching is the rapid cooling of a workpiece in water, oil, polymer, air, or other fluids to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favorable, and kinetically accessible; for instance, quenching can reduce the crystal grain size of both metallic and plastic materials, increasing their hardness. In metallurgy, quenching is most commonly used to harden steel by inducing a martensite transformation, where the steel must be rapidly cooled through its eutectoid point, the temperature at which austenite becomes unstable. In steel alloyed with metals such as nickel and manganese, the eutectoid temperature becomes much lower, but the kinetic barriers to phase transformation remain the same. This allows quenching to start at a lowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annealing (metallurgy)
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating rate and cooling rate. Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raising (metalwork)
Raising is a metalworking technique whereby sheet metal is formed over a solid object by repeated "courses" of hammering and annealing. A sheet metal worker is often required to raise, or bump, the work into form from the flat metal by means of a raising hammer and raising block. The raising block is made from substance giving resistance to the blows. A modern term is ''synclastic raising'', the dominant curves of the object being forged are at right angles and move in the same direction; as in a bowl. This results in a surface possessing elliptic geometry. ''Anticlastic raising'', on the other hand, refers to shaping an object where the dominant axes move in opposite directions; a familiar example of this is a potato crisp. This results in a surface possessing hyperbolic geometry. See also * Planishing * Sinking (metalworking) Sinking, also known as doming, dishing or dapping, is a metalworking technique whereby flat sheet metal is formed into a non-flat object by hammerin ...

Federigo Da Montefeltro
Federico da Montefeltro, also known as Federico III da Montefeltro Order of the Garter, KG (7 June 1422 – 10 September 1482), was one of the most successful mercenary captains (''condottiero, condottieri'') of the Italian Renaissance, and Duke of Urbino, lord of Urbino from 1444 (as Duke from 1474) until his death. A renowned intellectual Renaissance Humanist, humanist and civil leader in Urbino on top of his impeccable reputation for martial skill and honor, he commissioned the construction of a great library, perhaps the largest of Italy after the Vatican, with his own team of scribes in his scriptorium, and assembled around him a large humanistic court in the Ducal Palace, Urbino, Ducal Palace, Urbino, designed by Luciano Laurana and Francesco di Giorgio Martini. Biography Federico was born in Castello di Petroia in Gubbio, the illegitimate son of Guidantonio da Montefeltro, lord of Urbino, Gubbio and Casteldurante, and Duke of Spoleto. Two years later he was legitimized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard (mail Collar)
A standard, also called a pizaine, was a collar of mail often worn with plate armour. Construction The standard protected the throat and neck and usually extended over the shoulders; it was in use from the 14th to the 16th century. Unlike the similar aventail, it was not attached to a helmet. It was called a standard because the part encircling the neck and throat was able to stand upright without any external stiffening. This part of the standard was composed of links joined 6-in-1, which made it less flexible and also stronger; the usual, more flexible, ratio of mail linking was 4-in-1. The lower, shoulder-covering, part of the standard was of 4-in-1 linked mail. Some standards were decorated with edging in brass or bronze links (sometimes gilded), and/or were given a zig-zag lower edge (vandyked). Use Standards were sometimes worn under an aventail, or even a gorget, for extra protection. However, standards were often worn without other neck protection by soldiers who valued a ...

Corinthian Helmet
The Corinthian helmet originated in ancient Greece and took its name from the city-state of Corinth. It was a helmet made of bronze which in its later styles covered the entire head and neck, with slits for the eyes and mouth. A large curved projection protected the nape of the neck. Out of combat, a Greek hoplite would wear the helmet tipped upward for comfort. This practice gave rise to a series of variant forms in Italy, where the slits were almost closed, since the helmet was no longer pulled over the face but worn cap-like. Although the classical Corinthian helmet fell out of use among the Greeks in favour of more open types, the Italo-Corinthian types remained in use until the 1st century AD, being used, among others, by the Roman army. Physical evidence Apparently (judging from artistic and archaeological evidence) the most popular helmet during the Archaic and early Classical periods, the style gradually gave way to the more open Thracian helmet, Chalcidian helmet a ...

Classical Greece
Classical Greece was a period of around 200 years (the 5th and 4th centuries BC) in Ancient Greece,The "Classical Age" is "the modern designation of the period from about 500 B.C. to the death of Alexander the Great in 323 B.C." ( Thomas R. Martin, ''Ancient Greece'', Yale University Press, 1996, p. 94). marked by much of the eastern Aegean and northern regions of Greek culture (such as Ionia and Macedonia) gaining increased autonomy from the Persian Empire; the peak flourishing of democratic Athens; the First and Second Peloponnesian Wars; the Spartan and then Theban hegemonies; and the expansion of Macedonia under Philip II. Much of the early defining politics, artistic thought (architecture, sculpture), scientific thought, theatre, literature and philosophy of Western civilization derives from this period of Greek history, which had a powerful influence on the later Roman Empire. The Classical era ended after Philip II's unification of most of the Greek world against th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
