Arch bridge
–
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, a viaduct may be made from a series of arches, although other more economical structures are typically used today. Possibly the oldest existing bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch, a more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries. Roman arch bridges were usually semicircular, although a number were segmental arch bridges, generally, Roman bridges featured wedge-shaped primary arch stones of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts, such as the Pont du Gard and Segovia Aqueduct. Their bridges featured from an early time onwards flood openings in the piers, e. g. in the Pons Fabricius in Rome, Roman engineers were the first and until the industrial revolution the only ones to construct bridges with concrete, which they called Opus caementicium. The outside was covered with brick or ashlar, as in the Alcántara bridge. The Romans also introduced segmental arch bridges into bridge construction, trajans bridge over the Danube featured open-spandrel segmental arches made of wood. This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m long Puente Romano at Mérida. The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch, in medieval Europe, bridge builders improved on the Roman structures by using narrower piers, thinner arch barrels and lower span-rise ratios on bridges. Gothic pointed arches were introduced, reducing lateral thrust. The 14th century in particular saw bridge building reaching new heights, the bridge at Trezzo sullAdda, destroyed in the 15th century, even featured a span length of 72 m, not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio combined sound engineering with aesthetical appeal, the three elegant arches of the Renaissance Ponte Santa Trinita constitute the oldest elliptic arch bridge worldwide. In China, the oldest existing bridge is the Zhaozhou Bridge of 605 AD. The Zhaozhou Bridge, with a length of 167 feet and span of 123 feet, is the worlds first wholly stone open-spandrel segmental arch bridge, Bridges with perforated spandrels can be found worldwide, such as in China

Bridge
–
A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose, the Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced back to Proto-Indo-European *bʰrēw-. The word for the game of the same name has a different origin. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support, some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence, several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese. The greatest bridge builders of antiquity were the ancient Romans, the Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. An example is the Alcántara Bridge, built over the river Tagus, the Romans also used cement, which reduced the variation of strength found in natural stone. One type of cement, called pozzolana, consisted of water, lime, sand, brick and mortar bridges were built after the Roman era, as the technology for cement was lost. In India, the Arthashastra treatise by Kautilya mentions the construction of dams, a Mauryan bridge near Girnar was surveyed by James Princep. The bridge was swept away during a flood, and later repaired by Puspagupta, the use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India and this bridge is also historically significant as it is the worlds oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge, rope bridges, a simple type of suspension bridge, were used by the Inca civilization in the Andes mountains of South America, just prior to European colonization in the 16th century. During the 18th century there were innovations in the design of timber bridges by Hans Ulrich Grubenmann, Johannes Grubenmann. The first book on bridge engineering was written by Hubert Gautier in 1716, a major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross the river Severn, with the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a tensile strength, much larger bridges were built. In 1927 welding pioneer Stefan Bryła designed the first welded bridge in the world

Venice
–
Venice is a city in northeastern Italy and the capital of the Veneto region. It is situated across a group of 118 small islands that are separated by canals and these are located in the shallow Venetian Lagoon, an enclosed bay that lies between the mouths of the Po and the Piave Rivers. Parts of Venice are renowned for the beauty of their settings, their architecture, the lagoon and a part of the city are listed as a World Heritage Site. In 2014,264,579 people resided in Comune di Venezia, together with Padua and Treviso, the city is included in the Padua-Treviso-Venice Metropolitan Area, with a total population of 2.6 million. PATREVE is a metropolitan area without any degree of autonomy. The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC, the city was historically the capital of the Republic of Venice. Venice has been known as the La Dominante, Serenissima, Queen of the Adriatic, City of Water, City of Masks, City of Bridges, The Floating City, and City of Canals. The City State of Venice is considered to have been the first real international financial center which gradually emerged from the 9th century to its peak in the 14th century and this made Venice a wealthy city throughout most of its history. It is also known for its several important artistic movements, especially the Renaissance period, Venice has played an important role in the history of symphonic and operatic music, and it is the birthplace of Antonio Vivaldi. Venice has been ranked the most beautiful city in the world as of 2016, the name Venetia, however, derives from the Roman name for the people known as the Veneti, and called by the Greeks Eneti. The meaning of the word is uncertain, although there are other Indo-European tribes with similar-sounding names, such as the Celtic Veneti, Baltic Veneti, and the Slavic Wends. Linguists suggest that the name is based on an Indo-European root *wen, so that *wenetoi would mean beloved, lovable, a connection with the Latin word venetus, meaning the color sea-blue, is also possible. The alternative obsolete form is Vinegia, some late Roman sources reveal the existence of fishermen on the islands in the original marshy lagoons. They were referred to as incolae lacunae, the traditional founding is identified with the dedication of the first church, that of San Giacomo on the islet of Rialto — said to have taken place at the stroke of noon on 25 March 421. Beginning as early as AD166 to 168, the Quadi and Marcomanni destroyed the center in the area. The Roman defences were again overthrown in the early 5th century by the Visigoths and, some 50 years later, New ports were built, including those at Malamocco and Torcello in the Venetian lagoon. The tribuni maiores, the earliest central standing governing committee of the islands in the Lagoon, the traditional first doge of Venice, Paolo Lucio Anafesto, was actually Exarch Paul, and his successor, Marcello Tegalliano, was Pauls magister militum. In 726 the soldiers and citizens of the Exarchate rose in a rebellion over the controversy at the urging of Pope Gregory II

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Limestone
–
Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate, about 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, most cave systems are through limestone bedrock. The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778, like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts and these organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die. Limestone often contains variable amounts of silica in the form of chert or siliceous skeletal fragment, some limestones do not consist of grains at all, and are formed completely by the chemical precipitation of calcite or aragonite, i. e. travertine. Secondary calcite may be deposited by supersaturated meteoric waters and this produces speleothems, such as stalagmites and stalactites. Another form taken by calcite is oolitic limestone, which can be recognized by its granular appearance, the primary source of the calcite in limestone is most commonly marine organisms. Some of these organisms can construct mounds of rock known as reefs, below about 3,000 meters, water pressure and temperature conditions cause the dissolution of calcite to increase nonlinearly, so limestone typically does not form in deeper waters. Limestones may also form in lacustrine and evaporite depositional environments, calcite can be dissolved or precipitated by groundwater, depending on several factors, including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits a characteristic called retrograde solubility, in which it becomes less soluble in water as the temperature increases. Impurities will cause limestones to exhibit different colors, especially with weathered surfaces, Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock, when conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together, or it can fill fractures. Travertine is a banded, compact variety of limestone formed along streams, particularly there are waterfalls. Calcium carbonate is deposited where evaporation of the leaves a solution supersaturated with the chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls, coquina is a poorly consolidated limestone composed of pieces of coral or shells. During regional metamorphism that occurs during the building process, limestone recrystallizes into marble

Doge's Palace
–
The Doges Palace is a palace built in Venetian Gothic style, and one of the main landmarks of the city of Venice in northern Italy. The palace was the residence of the Doge of Venice, the authority of the former Republic of Venice. Today, it is one of the 11 museums run by the Fondazione Musei Civici di Venezia. In 810, Doge Angelo Partecipazio moved the seat of government from the island of Malamocco to the area of the present-day Rialto, when it was decided a palatium duci, a ducal palace, should be built. However, no remains of that 9th-century building as the palace was partially destroyed in the 10th century by a fire. The following reconstruction works were undertaken at the behest of Doge Sebastiano Ziani, a great reformer, he would drastically change the entire layout of the St. The new palace was built out of fortresses, one façade to the Piazzetta, political changes in the mid-13th century led to the need to re-think the palaces structure due to the considerable increase in the number of the Great Councils members. The new Gothic palaces constructions started around 1340, focusing mostly on the side of the building facing the lagoon, in 1483, a violent fire broke out in the side of the palace overlooking the canal, where the Doges Apartments were. Once again, an important reconstruction became necessary and was commissioned from Antonio Rizzo, another huge fire in 1547 destroyed some of the rooms on the second floor, but fortunately without undermining the structure as a whole. However, there are some classical features — for example, since the 16th century, as well as being the ducal residence, the palace housed political institutions of the Republic of Venice until the Napoleonic occupation of the city in 1797, when its role inevitably changed. Venice was subjected first to French rule, then to Austrian, over this period, the palace was occupied by various administrative offices as well as housing the Biblioteca Marciana and other important cultural institutions within the city. In 1923, the Italian State, owner of the building, since 1996, the Doge’s Palace has been part of the Venetian museums network, which has been under the management of the Fondazione Musei Civici di Venezia since 2008. The ground floor arcade and the loggia above are decorated with 14th- and 15th-century capitals, in 1438–1442, Giovanni Bon and Bartolomeo Bon built and adorned the Porta della Carta, which served as the ceremonial entrance to the building. In the space above the cornice, there is a portrait of the Doge Francesco Foscari kneeling before the St. This is, however, a 19th-century work by Luigi Ferrari, nowadays, the public entrance to the Doges Palace is via the Porta del Frumento, on the waterfront side of the building. The north side of the courtyard is closed by the junction between the palace and St, mark’s Basilica, which used to be the Doge’s chapel. At the center of the courtyard stand two well-heads dating from the mid-16th century, in 1485, the Great Council decided that a ceremonial staircase should be built within the courtyard. Since 1567, the Giants’ Staircase is guarded by Sansovino’s two colossal statues of Mars and Neptune, which represents Venice’s power by land and by sea, members of the Senate gathered before government meetings in the Senator’s Courtyard, to the right of the Giants’ Staircase

Prison
–
Besides their use for punishing crimes, jails and prisons are frequently used by authoritarian regimes against perceived opponents. Prisons often have facilities that are designed with long term confinement in mind in comparison to jails. In times of war, prisoners of war or detainees may be detained in prisons or prisoner of war camps. The use of prisons can be traced back to the rise of the state as a form of social organization, corresponding with the advent of the state was the development of written language, which enabled the creation of formalized legal codes as official guidelines for society. The best known of early legal codes is the Code of Hammurabi. Some Ancient Greek philosophers, such as Plato, began to develop ideas of using punishment to reform instead of simply using it as retribution. Imprisonment as a penalty was used initially for those who could not afford to pay their fines, eventually, since impoverished Athenians could not pay their fines, leading to indefinite periods of imprisonment, time limits were set instead. The prison in Ancient Athens was known as the desmoterion, the Romans were among the first to use prisons as a form of punishment, rather than simply for detention. A variety of existing structures were used to house prisoners, such as cages, basements of public buildings. One of the most notable Roman prisons was the Mamertine Prison, the Mamertine Prison was located within a sewer system beneath ancient Rome and contained a large network of dungeons where prisoners were held in squalid conditions, contaminated with human waste. Forced labor on public projects was also a common form of punishment. In many cases, citizens were sentenced to slavery, often in ergastula, during the Middle Ages in Europe, castles, fortresses, and the basements of public buildings were often used as makeshift prisons. Another common punishment was sentencing people to slavery, which involved chaining prisoners together in the bottoms of ships. However, the concept of the modern prison largely remained unknown until the early 19th-century, Punishment usually consisted of physical forms of punishment, including capital punishment, mutilation, flagellation, branding, and non-physical punishments, such as public shaming rituals. However, an important innovation at the time was the Bridewell House of Corrections, located at Bridewell Palace in London and these houses held mostly petty offenders, vagrants, and the disorderly local poor. In these facilities, inmates were given jobs, and through prison labor they were taught how to work for a living, by the end of the 17th century, houses of correction were absorbed into local prison facilities under the control of the local justice of the peace. From the late 17th century and during the 18th century, popular resistance to public execution, rulers began looking for means to punish and control their subjects in a way that did not cause people to associate them with spectacles of tyrannical and sadistic violence. They developed systems of mass incarceration, often with hard labor, the prison reform movement that arose at this time was heavily influenced by two somewhat contradictory philosophies

Lord Byron
–
George Gordon Byron, 6th Baron Byron, FRS, commonly known simply as Lord Byron, was a British poet, peer, politician, and a leading figure in the Romantic movement. Among his best-known works are the narrative poems, Don Juan and Childe Harolds Pilgrimage. Byron is regarded as one of the greatest British poets and remains widely read and influential and he travelled extensively across Europe, especially in Italy, where he lived for seven years with the struggling poet Percy Bysshe Shelley. Later in his life, Byron joined the Greek War of Independence fighting the Ottoman Empire. He died in 1824 at the age of 36 from a fever contracted while in Missolonghi, ethel Colburn Mayne states that George Gordon Byron was born on 22 January 1788 in a house on 24 Holles Street in London. However, Robert Charles Dallas in his Recollections states that Byron was born in Dover and he was the son of Captain John Mad Jack Byron and his second wife, the former Catherine Gordon, a descendant of Cardinal Beaton and heiress of the Gight estate in Aberdeenshire, Scotland. Byrons father had seduced the married Marchioness of Carmarthen and, after she divorced her husband. His treatment of her was described as brutal and vicious, in order to claim his second wifes estate in Scotland, Byrons father took the additional surname Gordon, becoming John Byron Gordon, and he was occasionally styled John Byron Gordon of Gight. Byron himself used this surname for a time and was registered at school in Aberdeen as George Byron Gordon, at the age of 10, he inherited the English Barony of Byron of Rochdale, becoming Lord Byron, and eventually dropped the double surname. Byrons paternal grandparents were Vice-Admiral the Hon. John Foulweather Jack Byron, vice Admiral John Byron had circumnavigated the globe, and was the younger brother of the 5th Baron Byron, known as the Wicked Lord. He was christened, at St Marylebone Parish Church, George Gordon Byron after his maternal grandfather George Gordon of Gight, a descendant of James I of Scotland, Mad Jack Byron married his second wife for the same reason that he married his first, her fortune. In a move to avoid his creditors, Catherine accompanied her husband to France in 1786. He was born on 22 January in lodgings at Holles Street in London, Catherine moved back to Aberdeenshire in 1790, where Byron spent his childhood. His father soon joined them in their lodgings in Queen Street, Catherine regularly experienced mood swings and bouts of melancholy, which could be partly explained by her husbands continuing to borrow money from her. As a result, she fell even further into debt to support his demands and it was one of these importunate loans that allowed him to travel to Valenciennes, France, where he died in 1791. When Byrons great-uncle, the wicked Lord Byron, died on 21 May 1798, described as a woman without judgment or self-command, Catherine either spoiled and indulged her son or vexed him with her capricious stubbornness. Her drinking disgusted him, and he often mocked her for being short and corpulent and she once retaliated and, in a fit of temper, referred to him as a lame brat. Langley-Moore questions the Galt claim that she over-indulged in alcohol, upon the death of Byrons mother-in-law Judith Noel, the Hon

Jacques Offenbach
–
Jacques Offenbach was a German-born French composer, cellist and impresario of the romantic period. He is remembered for his nearly 100 operettas of the 1850s–1870s and he was a powerful influence on later composers of the operetta genre, particularly Johann Strauss, Jr. and Arthur Sullivan. His best-known works were revived during the 20th century. The Tales of Hoffman remains part of the opera repertory. Born in Cologne, the son of a cantor, Offenbach showed early musical talent. At the age of 14, he was accepted as a student at the Paris Conservatoire but found academic study unfulfilling, from 1835 to 1855 he earned his living as a cellist, achieving international fame, and as a conductor. His ambition, however, was to compose pieces for the musical theatre. Finding the management of Paris Opéra-Comique company uninterested in staging his works, there he presented a series of his own small-scale pieces, many of which became popular. In 1858, Offenbach produced his first full-length operetta, Orphée aux enfers, during the 1860s, he produced at least 18 full-length operettas, as well as more one-act pieces. His works from this period included La belle Hélène, La Vie parisienne, La Grande-Duchesse de Gérolstein, Offenbach became associated with the Second French Empire of Napoleon III, the emperor and his court were genially satirised in many of Offenbachs operettas. Napoleon III personally granted him French citizenship and the Légion dHonneur, with the outbreak of the Franco-Prussian War in 1870, Offenbach found himself out of favour in Paris because of his imperial connections and his German birth. He remained successful in Vienna and London, however and he re-established himself in Paris during the 1870s, with revivals of some of his earlier favourites and a series of new works, and undertook a popular U. S. tour. In his last years he strove to finish The Tales of Hoffmann, but died before the premiere of the opera, Offenbach was born Jacob or Jakob Offenbach to a Jewish family, in the German city of Cologne, which was then a part of Prussia. His birthplace in the Großen Griechenmarkt was a distance from the square that is now named after him. He was the son and the seventh of ten children of Isaac Juda Offenbach né Eberst and his wife Marianne. Isaac, who came from a family, had abandoned his original trade as a bookbinder and earned an itinerant living as a cantor in synagogues. He was generally known as der Offenbacher, after his native town, Offenbach am Main, in 1816 he settled in Cologne, where he became established as a teacher, giving lessons in singing, violin, flute and guitar, and composing both religious and secular music. When Jacob was six years old, his father taught him to play the violin, within two years the boy was composing songs and dances, and at the age of nine he took up the cello

John Singer Sargent
–
John Singer Sargent was an American artist, considered the leading portrait painter of his generation for his evocations of Edwardian era luxury. During his career, he created roughly 900 oil paintings and more than 2,000 watercolors, as well as countless sketches and his oeuvre documents worldwide travel, from Venice to the Tyrol, Corfu, the Middle East, Montana, Maine, and Florida. His parents were American, but he was trained in Paris prior to moving to London and his commissioned works were consistent with the grand manner of portraiture, while his informal studies and landscape paintings displayed a familiarity with Impressionism. In later life Sargent expressed ambivalence about the restrictions of formal portrait work and he lived most of his life in Europe. Art historians generally ignored the society such as Sargent until the late 20th century. Before Sargents birth, his father, FitzWilliam, was an eye surgeon at the Wills Eye Hospital in Philadelphia 1844–1854, after Johns older sister died at the age of two, his mother, Mary, suffered a breakdown, and the couple decided to go abroad to recover. They remained nomadic expatriates for the rest of their lives, although based in Paris, Sargents parents moved regularly with the seasons to the sea and the mountain resorts in France, Germany, Italy, and Switzerland. While Mary was pregnant, they stopped in Florence, Tuscany, Sargent was born there in 1856. A year later, his sister Mary was born, after her birth, FitzWilliam reluctantly resigned his post in Philadelphia and accepted his wifes entreaties to remain abroad. They lived modestly on an inheritance and savings, living a quiet life with their children. They generally avoided society and other Americans except for friends in the art world, four more children were born abroad, of whom only two lived past childhood. Although his father was a patient teacher of basic subjects, young Sargent was a rambunctious child, as his father wrote home, He is quite a close observer of animated nature. His mother was convinced that traveling around Europe, and visiting museums and churches. Several attempts to have him formally schooled failed, owing mostly to their itinerant life, Sargents mother was a fine amateur artist and his father was a skilled medical illustrator. Early on, she gave him sketchbooks and encouraged drawing excursions, young Sargent worked with care on his drawings, and he enthusiastically copied images from The Illustrated London News of ships and made detailed sketches of landscapes. FitzWilliam had hoped that his sons interest in ships and the sea might lead him toward a naval career, at thirteen, his mother reported that John sketches quite nicely, & has a remarkably quick and correct eye. If we could afford to give him really good lessons, he would soon be quite a little artist, at the age of thirteen, he received some watercolor lessons from Carl Welsch, a German landscape painter. Although his education was far from complete, Sargent grew up to be a literate and cosmopolitan young man, accomplished in art, music

Wikimedia Commons is an online repository of free-use images, sound, and other media files. It is a project of the Wikimedia Foundation, the repository contains over 38 million media files. In July 2013, the number of edits on Commons reached 100,000,000, the project was proposed by Erik Möller in March 2004 and launched on September 7,2004. The expression educational is to be according to its broad meaning of providing knowledge. Wikimedia Commons itself does not allow fair use or uploads under non-free licenses, for this reason, Wikimedia Commons always hosts freely licensed media and deletes copyright violations. The default language for Commons is English, but registered users can customize their interface to use any other user interface translations. Many content pages, in particular policy pages and portals, have also translated into various languages. Files on Wikimedia Commons are categorized using MediaWikis category system, in addition, they are often collected on individual topical gallery pages. While the project was proposed to also contain free text files. In 2012, BuzzFeed described Wikimedia Commons as littered with dicks, in 2010, Wikipedia co-founder Larry Sanger reported Wikimedia Commons to the FBI for hosting sexualized images of children known as lolicon. Wales responded to the backlash from the Commons community by voluntarily relinquishing some site privileges, over time, additional functionality has been developed to interface Wikimedia Commons with the other Wikimedia projects. Specialized uploading tools and scripts such as Commonist have been created to simplify the process of uploading large numbers of files. In order to free content photos uploaded to Flickr, users can participate in a defunct collaborative external review process. The site has three mechanisms for recognizing quality works, one is known as Featured pictures, where works are nominated and other community members vote to accept or reject the nomination. This process began in November 2004, another process known as Quality images began in June 2006, and has a simpler nomination process comparable to Featured pictures. Quality images only accepts works created by Wikimedia users, whereas Featured pictures additionally accepts nominations of works by third parties such as NASA, the three mentioned processes select a slight part from the total number of files. However, Commons collects files of all quality levels, from the most professional level across simple documental, files with specific defects can be tagged for improvement and warning or even proposed for deletion but there exists no process of systematic rating of all files. The site held its inaugural Picture of the Year competition, for 2006, all images that were made a Featured picture during 2006 were eligible, and voted on by eligible Wikimedia users during two rounds of voting

Venetian Arsenal
–
The Venetian Arsenal is a complex of former shipyards and armories clustered together in the city of Venice in northern Italy. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republics naval power during the part of the second millennium AD. It was one of the earliest large-scale industrial enterprises in history, construction of the Arsenal began around 1104, during Venices republican era. It became the largest industrial complex in Europe before the Industrial Revolution, spanning an area of about 45 hectares, surrounded by a 2-mile rampart, laborers and shipbuilders regularly worked within the Arsenal, building ships that sailed from the citys port. These parts could then be assembled into a ship in as little as one day, an exclusive forest owned by the Arsenal navy, in the Montello hills area of Veneto, provided the Arsenals wood supply. It is located in the Castello district of Venice, and it is now owned by the state and it definitely existed by the early 13th century. Initially the state dockyard worked merely to maintain privately built naval ships and it enabled all the states navy and the larger merchant ships to be both constructed and maintained in one place. The Arsenal incidentally became an important center for manufacture. Venice developed methods of mass-producing warships in the Arsenal, including the frame-first system to replace the Roman hull-first practice and this new system was much faster and required less wood. The muzzle velocity of handguns was improved beyond that of the crossbow, the Arsenals main gate, the Porta Magna, was built around 1460 and was the first Classical revival structure built in Venice. It was perhaps built by Antonio Gambello from a design by Jacopo Bellini, two lions taken from Greece situated beside it were added in 1687. One of the lions, known as the Piraeus Lion, has runic defacements carved in it by invading Scandinavian mercenaries during the 11th century, in the late 16th century, the Arsenals designers experimented with larger ships as platforms for heavy naval guns. The largest was the galleass, already used at the Battle of Lepanto against the Ottoman Turks and it was huge, propelled by both sails and oars, with guns mounted on wheeled carriages along the sides in the modern fashion. It was slow and unwieldy in battle, however, and few were ever built, the galleon, also developed at the Arsenal, was an armed sailing ship, a slimmer version of the merchant round ship.
