The public domain consists of all the creative works to which no exclusive intellectual property rights apply. Those rights may have been forfeited, expressly waived, or may be inapplicable; the works of William Shakespeare and Beethoven, most early silent films, are in the public domain either by virtue of their having been created before copyright existed, or by their copyright term having expired. Some works are not covered by copyright, are therefore in the public domain—among them the formulae of Newtonian physics, cooking recipes, all computer software created prior to 1974. Other works are dedicated by their authors to the public domain; the term public domain is not applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission". As rights vary by country and jurisdiction, a work may be subject to rights in one country and be in the public domain in another; some rights depend on registrations on a country-by-country basis, the absence of registration in a particular country, if required, gives rise to public-domain status for a work in that country.
The term public domain may be interchangeably used with other imprecise or undefined terms such as the "public sphere" or "commons", including concepts such as the "commons of the mind", the "intellectual commons", the "information commons". Although the term "domain" did not come into use until the mid-18th century, the concept "can be traced back to the ancient Roman Law, as a preset system included in the property right system." The Romans had a large proprietary rights system where they defined "many things that cannot be owned" as res nullius, res communes, res publicae and res universitatis. The term res nullius was defined as things not yet appropriated; the term res communes was defined as "things that could be enjoyed by mankind, such as air and ocean." The term res publicae referred to things that were shared by all citizens, the term res universitatis meant things that were owned by the municipalities of Rome. When looking at it from a historical perspective, one could say the construction of the idea of "public domain" sprouted from the concepts of res communes, res publicae, res universitatis in early Roman law.
When the first early copyright law was first established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by French jurists in the 18th century. Instead of "public domain", they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law; the phrase "fall in the public domain" can be traced to mid-19th century France to describe the end of copyright term. The French poet Alfred de Vigny equated the expiration of copyright with a work falling "into the sink hole of public domain" and if the public domain receives any attention from intellectual property lawyers it is still treated as little more than that, left when intellectual property rights, such as copyright and trademarks, expire or are abandoned. In this historical context Paul Torremans describes copyright as a, "little coral reef of private right jutting up from the ocean of the public domain." Copyright law differs by country, the American legal scholar Pamela Samuelson has described the public domain as being "different sizes at different times in different countries".
Definitions of the boundaries of the public domain in relation to copyright, or intellectual property more regard the public domain as a negative space. According to James Boyle this definition underlines common usage of the term public domain and equates the public domain to public property and works in copyright to private property. However, the usage of the term public domain can be more granular, including for example uses of works in copyright permitted by copyright exceptions; such a definition regards work in copyright as private property subject to fair-use rights and limitation on ownership. A conceptual definition comes from Lange, who focused on what the public domain should be: "it should be a place of sanctuary for individual creative expression, a sanctuary conferring affirmative protection against the forces of private appropriation that threatened such expression". Patterson and Lindberg described the public domain not as a "territory", but rather as a concept: "here are certain materials – the air we breathe, rain, life, thoughts, ideas, numbers – not subject to private ownership.
The materials that compose our cultural heritage must be free for all living to use no less than matter necessary for biological survival." The term public domain may be interchangeably used with other imprecise or undefined terms such as the "public sphere" or "commons", including concepts such as the "commons of the mind", the "intellectual commons", the "information commons". A public-domain book is a book with no copyright, a book, created without a license, or a book where its copyrights expired or have been forfeited. In most countries the term of protection of copyright lasts until January first, 70 years after the death of the latest living author; the longest copyright term is in Mexico, which has life plus 100 years for all deaths since July 1928. A notable exception is the United States, where every book and tale published prior to 1924 is in the public domain.
In Greek mythology, Daedalus was a skillful craftsman and artist, was seen as a symbol of wisdom and power. He is the father of Icarus, the uncle of Perdix, also the father of Iapyx, although this is unclear, he invented and built the labyrinth for king Minos of Crete, but shortly after finishing it king Minos had Daedalus imprisoned within the labyrinth. He and his son Icarus devised a plan to escape by using wings made of wax that Daedalus had invented, they escaped. The wax melted and Icarus fell to his death; this left Daedalus heartbroken. Daedalus's parentage was supplied as a addition, providing him with a father in Metion, Eupalamus, or Palamaon, a mother, Iphinoe, or Phrasmede. Daedalus had two sons: Iapyx, along with a nephew either Talos or Perdix. Athenians transferred Cretan Daedalus to make him Athenian-born, the grandson of the ancient king Erechtheus, claiming that Daedalus fled to Crete after killing his nephew Talos. Over time, other stories were told of Daedalus. Daedalus is first mentioned by Homer as the creator of a wide dancing-ground for Ariadne.
He created the Labyrinth on Crete, in which the Minotaur was kept. In the story of the labyrinth as told by the Hellenes, the Athenian hero Theseus is challenged to kill the Minotaur, finding his way with the help of Ariadne's thread. Daedalus' appearance in Homer is in an extended metaphor, "plainly not Homer's invention", Robin Lane Fox observes: "He is a point of comparison and so he belongs in stories which Homer's audience recognized." In Bronze Age Crete, an inscription da-da-re-jo-de has been read as referring to a place at Knossos, a place of worship. In Homer's language, daidala refers to finely crafted objects, they are objects of armor, but fine bowls and furnishings are daidala, on one occasion so are the "bronze-working" of "clasps, twisted brooches and necklaces" made by Hephaestus while cared for in secret by the goddesses of the sea. Ignoring Homer writers envisaged the Labyrinth as an edifice rather than a single dancing path to the center and out again, gave it numberless winding passages and turns that opened into one another, seeming to have neither beginning nor end.
Ovid, in his Metamorphoses, suggests that Daedalus constructed the Labyrinth so cunningly that he himself could escape it after he built it. Daedalus built the labyrinth for King Minos; the story is told that Poseidon had given a white bull to Minos so that he might use it as a sacrifice. Instead, Minos kept it for himself. For Pasiphaë, as Greek mythologers interpreted it, Daedalus built a wooden cow so she could mate with the bull, for the Greeks imagined the Minoan bull of the sun to be an actual, earthly bull, the slaying of which required a heroic effort by Theseus; this story thus encourages others to consider the long-term consequences of their own inventions with great care, lest those inventions do more harm than good. As in the tale of Icarus' wings, Daedalus is portrayed assisting in the creation of something that has subsequent negative consequences, in this case with his creation of the monstrous Minotaur's impenetrable Labyrinth, which made slaying the beast an endeavour of legendary difficulty.
The most familiar literary telling explaining Daedalus' wings is a late one, that of Ovid: in his Metamorphoses Daedalus was shut up in a tower to prevent the knowledge of his Labyrinth from spreading to the public. He could not leave Crete by sea, as the king kept a strict watch on all vessels, permitting none to sail without being searched. Since Minos controlled the land and sea routes, Daedalus set to work to fabricate wings for himself and his young son Icarus, he tied feathers together, from smallest to largest so as to form an increasing surface. He secured the feathers at their midpoints with string and at their bases with wax, gave the whole a gentle curvature like the wings of a bird; when the work was done, the artist, waving his wings, found himself buoyed upward and hung suspended, poising himself on the beaten air. He next equipped his son in the same manner, taught him how to fly; when both were prepared for flight, Daedalus warned Icarus not to fly too high, because the heat of the sun would melt the wax, nor too low, because the sea foam would soak the feathers.
They had passed Samos and Lebynthos by the time the boy, forgetting himself, began to soar upward toward the sun. The blazing sun softened the wax that held the feathers together and they came off. Icarus fell in the sea and drowned, his father cried, bitterly lamenting his own arts, called the island near the place where Icarus fell into the ocean Icaria in memory of his child. Some time the goddess Athena visited Daedalus and gave him wings, telling him to fly like a god. An early image of winged Daedalus appears on an Etruscan jug of ca 630 BC found at Cerveteri, where a winged figure captioned Taitale appears on one side of the vessel, paired on the other side, with Metaia, Medea: "its linking of these two mythical figures is unparalleled," Robin Lane Fox observes: "The link was based on their wondrous, miraculous art. Magically, Daedalus could fly, magically Medea was able to rejuvenate the old"; the image
Argos is a city in Argolis, the Peloponnese, Greece and is one of the oldest continuously inhabited cities in the world. It is a major center for the area. Since the 2011 local government reform it has been part of the municipality of Argos-Mykines, of which it is a municipal unit; the municipal unit has an area of 138.138 km2. It is 11 kilometres from Nafplion, its historic harbour. A settlement of great antiquity, Argos has been continuously inhabited as at least a substantial village for the past 7,000 years; the city is a member of the Most Ancient European Towns Network. A resident of the city of Argos is known as an Argive. However, this term is used to refer to those ancient Greeks who assaulted the city of Troy during the Trojan War. Numerous ancient monuments can be found in the city today. Agriculture is the mainstay of the local economy; the name of the city is ancient and several etymological theories have been proposed as an explanation to its meaning. The most popular one maintains that the name of the city is a remainder from the Pelasgian language, i.e. the one used by the people who first settled in the area, in which Argos meant "plain".
Alternatively, the name is associated with Argos, the third king of the city in ancient times, who renamed it after himself, thus replacing its older name Phoronikon Astu. It is believed that "Argos" is linked to the word "αργός", which meant "white". According to Strabo, the name could have originated from the word "αγρός" by antimetathesis of the consonants. Argos is traditionally considered to be the origins of the ancient Macedonian royal Greek house of the Argead dynasty; the most celebrated members were Philip II of Alexander the Great. As a strategic location on the fertile plain of Argolis, Argos was a major stronghold during the Mycenaean era. In classical times Argos was a powerful rival of Sparta for dominance over the Peloponnese, but was shunned by other Greek city-states after remaining neutral during the Greco-Persian Wars. There is evidence of continuous settlement in the area starting with a village about 7000 years ago in the late Neolithic, located on the foot of Aspida hill.
Since that time, Argos has been continually inhabited at the same geographical location. Its creation is attributed to Phoroneus, with its first name having been Phoronicon Asty, or the city of Phoroneus; the historical presence of the Pelasgian Greeks in the area can be witnessed in the linguistic remainders that survive up to today, such as the name of the city and "Larisa", the name of the city's castle located on the hill of the name. The city is located at a rather propitious area, among Nemea and Arcadia, it benefitted from its proximity to lake Lerna, which, at the time, was at a distance of one kilometre from the south end of Argos. Argos was a major stronghold of Mycenaean times, along with the neighbouring acropolis of Mycenae and Tiryns became a early settlement because of its commanding positions in the midst of the fertile plain of Argolis. Argos experienced its greatest period of expansion and power under the energetic 7th century BC ruler King Pheidon. Under Pheidon, Argos regained sway over the cities of the Argolid and challenged Sparta’s dominance of the Peloponnese.
Spartan dominance is thought to have been interrupted following the Battle of Hyssiae in 669-668 BC, in which Argive troops defeated the Spartans in a hoplite battle. During this time of its greatest power, the city boasted a pottery and bronze sculpturing school, pottery workshops and clothes producers. Moreover, at least 25 celebrations took place in the city, in addition to a regular local products exhibition. A sanctuary dedicated to Hera was found at the same spot where the monastery of Panagia Katekrymeni is located today. Pheidon extended Argive influence throughout Greece, taking control of the Olympic Games away from the citizens of Elis and appointing himself organizer during his reign. Pheidon is thought to have introduced reforms for standard weight and measures in Argos, a theory further reinforced with the unearthing of six "spits" of iron in an Argive Heraion remainders of a dedication from Pheidon. Argos remained neutral or the ineffective ally of Athens during the 5th century BC struggles between Sparta and Athens.
This, led to its weakening and loss of power, which in turn led to the shift of commercial focus from the Ancient Agora to the eastern side of the city, delimited by Danaou and Agiou Konstadinou streets. Argos played a minor role in the Corinthian Wars against Sparta, for a short period of time considered uniting with Corinth to form an expanded Argolid state. However, this plan never came to fruition, Argos continued to remain a minor power in Greek affairs. Argos was a democracy for most of the classical period, with only a brief hiatus between 418 and 416. Democracy was first established after a disastrous defeat by the Spartans at the Battle of Sepeia in 494. So many Argives were killed in the battle that a revolution ensued, in which disenfranchised outsiders were included in the state for the first time. Argive democracy included an Assembly, a Council, another body called'The Eighty,' whose precise responsibilities are obscure. Magistrates served six-month terms of office, with few exceptions, were audited at the end of their terms.
There is some evidence that ostracis
Cambridge University Press
Cambridge University Press is the publishing business of the University of Cambridge. Granted letters patent by King Henry VIII in 1534, it is the world's oldest publishing house and the second-largest university press in the world, it holds letters patent as the Queen's Printer. The press mission is "to further the University's mission by disseminating knowledge in the pursuit of education and research at the highest international levels of excellence". Cambridge University Press is a department of the University of Cambridge and is both an academic and educational publisher. With a global sales presence, publishing hubs, offices in more than 40 countries, it publishes over 50,000 titles by authors from over 100 countries, its publishing includes academic journals, reference works and English language teaching and learning publications. Cambridge University Press is a charitable enterprise that transfers part of its annual surplus back to the university. Cambridge University Press is both the oldest publishing house in the world and the oldest university press.
It originated from letters patent granted to the University of Cambridge by Henry VIII in 1534, has been producing books continuously since the first University Press book was printed. Cambridge is one of the two privileged presses. Authors published by Cambridge have included John Milton, William Harvey, Isaac Newton, Bertrand Russell, Stephen Hawking. University printing began in Cambridge when the first practising University Printer, Thomas Thomas, set up a printing house on the site of what became the Senate House lawn – a few yards from where the press's bookshop now stands. In those days, the Stationers' Company in London jealously guarded its monopoly of printing, which explains the delay between the date of the university's letters patent and the printing of the first book. In 1591, Thomas's successor, John Legate, printed the first Cambridge Bible, an octavo edition of the popular Geneva Bible; the London Stationers objected strenuously. The university's response was to point out the provision in its charter to print "all manner of books".
Thus began the press's tradition of publishing the Bible, a tradition that has endured for over four centuries, beginning with the Geneva Bible, continuing with the Authorized Version, the Revised Version, the New English Bible and the Revised English Bible. The restrictions and compromises forced upon Cambridge by the dispute with the London Stationers did not come to an end until the scholar Richard Bentley was given the power to set up a'new-style press' in 1696. In July 1697 the Duke of Somerset made a loan of £200 to the university "towards the printing house and presse" and James Halman, Registrary of the University, lent £100 for the same purpose, it was in Bentley's time, in 1698, that a body of senior scholars was appointed to be responsible to the university for the press's affairs. The Press Syndicate's publishing committee still meets and its role still includes the review and approval of the press's planned output. John Baskerville became University Printer in the mid-eighteenth century.
Baskerville's concern was the production of the finest possible books using his own type-design and printing techniques. Baskerville wrote, "The importance of the work demands all my attention. Caxton would have found nothing to surprise him if he had walked into the press's printing house in the eighteenth century: all the type was still being set by hand. A technological breakthrough was badly needed, it came when Lord Stanhope perfected the making of stereotype plates; this involved making a mould of the whole surface of a page of type and casting plates from that mould. The press was the first to use this technique, in 1805 produced the technically successful and much-reprinted Cambridge Stereotype Bible. By the 1850s the press was using steam-powered machine presses, employing two to three hundred people, occupying several buildings in the Silver Street and Mill Lane area, including the one that the press still occupies, the Pitt Building, built for the press and in honour of William Pitt the Younger.
Under the stewardship of C. J. Clay, University Printer from 1854 to 1882, the press increased the size and scale of its academic and educational publishing operation. An important factor in this increase was the inauguration of its list of schoolbooks. During Clay's administration, the press undertook a sizeable co-publishing venture with Oxford: the Revised Version of the Bible, begun in 1870 and completed in 1885, it was in this period as well that the Syndics of the press turned down what became the Oxford English Dictionary—a proposal for, brought to Cambridge by James Murray before he turned to Oxford. The appointment of R. T. Wright as Secretary of the Press Syndicate in 1892 marked the beginning of the press's development as a modern publishing business with a defined editorial policy and administrative structure, it was Wright who devised the plan for one of the most distinctive Cambridge contributions to publishing—the Cambridge Histories. The Cambridge Modern History was published
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most calcite or dolomite. Marble is not foliated, although there are exceptions. In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is used for sculpture and as a building material; the word "marble" derives from the Ancient Greek μάρμαρον, from μάρμαρος, "crystalline rock, shining stone" from the verb μαρμαίρω, "to flash, gleam". This stem is the ancestor of the English word "marmoreal", meaning "marble-like." While the English term "marble" resembles the French marbre, most other European languages, more resemble the original Ancient Greek. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most limestone or dolomite rock. Metamorphism causes variable recrystallization of the original carbonate mineral grains; the resulting marble rock is composed of an interlocking mosaic of carbonate crystals.
Primary sedimentary textures and structures of the original carbonate rock have been modified or destroyed. Pure white marble is the result of metamorphism of a pure limestone or dolomite protolith; the characteristic swirls and veins of many colored marble varieties are due to various mineral impurities such as clay, sand, iron oxides, or chert which were present as grains or layers in the limestone. Green coloration is due to serpentine resulting from magnesium-rich limestone or dolostone with silica impurities; these various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism. Examples of notable marble varieties and locations: White marble has been prized for its use in sculptures since classical times; this preference has to do with its softness, which made it easier to carve, relative isotropy and homogeneity, a relative resistance to shattering. The low index of refraction of calcite allows light to penetrate several millimeters into the stone before being scattered out, resulting in the characteristic waxy look which gives "life" to marble sculptures of any kind, why many sculptors preferred and still prefer marble for sculpting.
Construction marble is a stone, composed of calcite, dolomite or serpentine, capable of taking a polish. More in construction the dimension stone trade, the term "marble" is used for any crystalline calcitic rock useful as building stone. For example, Tennessee marble is a dense granular fossiliferous gray to pink to maroon Ordovician limestone, that geologists call the Holston Formation. Ashgabat, the capital city of Turkmenistan, was recorded in the 2013 Guinness Book of Records as having the world's highest concentration of white marble buildings. According to the United States Geological Survey, U. S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate.
U. S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for Marble Index has shown a growth of 12% annually for the 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile. In 1998, marble production was dominated by 4 countries that accounted for half of world production of marble and decorative stone. Italy and China were the world leaders, each representing 16% of world production, while Spain and India produced 9% and 8%, respectively. Italy is the world leader in marble export, with 20% share in global marble production, followed by China with 16%, India with 10%, Spain with 6%, Portugal with 5%. Dust produced by cutting marble could cause lung disease but more research needs to be carried out on whether dust filters and other safety products reduce this risk; the Occupational Safety and Health Administration has set the legal limit for marble exposure in the workplace as 15 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday.
The National Institute for Occupational Safety and Health has set a recommended exposure limit of 10 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday. Acids damage marble, because the calcium carbonate in marble reacts with them, releasing carbon dioxide: CaCO3 + 2H+ → Ca2+ + CO2 + H2O Thus, vinegar or other acidic solutions should never be used on marble. Outdoor marble statues, gravestones, or other marble structures are damaged by acid rain; the haloalkaliphilic methylotrophic bacterium Methylophaga murata was isolated from deteriorating marble in the Kremlin. Bacterial and fungal degradation was detected in four samples of marble from Milan cathedral; as the favorite medium for Greek and Roman sculptors and architects, marble has become a cultural symbol of tradition and refined taste. Its varied and colorful patterns make i
Crete is the largest and most populous of the Greek islands, the 88th largest island in the world and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia and Corsica. Crete and a number of surrounding islands and islets constitute the region of Crete, one of the 13 top-level administrative units of Greece; the capital and the largest city is Heraklion. As of 2011, the region had a population of 623,065. Crete forms a significant part of the economy and cultural heritage of Greece, while retaining its own local cultural traits, it was once the centre of the Minoan civilisation, the earliest known civilisation in Europe. The palace of Knossos lies in Crete; the island is first referred to as Kaptara in texts from the Syrian city of Mari dating from the 18th century BC, repeated in Neo-Assyrian records and the Bible. It was known in ancient Egyptian as Keftiu suggesting a similar Minoan name for the island; the current name of Crete is thought to be first attested in Mycenaean Greek texts written in Linear B, through the words ke-re-te, ke-re-si-jo, "Cretan".
In Ancient Greek, the name Crete first appears in Homer's Odyssey. Its etymology is unknown. One proposal derives it from a hypothetical Luwian word, *kursatta. In Latin, it became Creta; the original Arabic name of Crete was Iqrīṭiš, but after the Emirate of Crete's establishment of its new capital at ربض الخندق Rabḍ al-Ḫandaq, both the city and the island became known as Χάνδαξ or Χάνδακας, which gave Latin and Venetian Candia, from which were derived French Candie and English Candy or Candia. Under Ottoman rule, in Ottoman Turkish, Crete was called Girit. Crete is the fifth largest island in the Mediterranean Sea, it is located in the southern part of the Aegean Sea separating the Aegean from the Libyan Sea. The island has an elongated shape: it spans 260 km from east to west, is 60 km at its widest point, narrows to as little as 12 km. Crete covers an area of 8,336 km2, with a coastline of 1,046 km, it lies 160 km south of the Greek mainland. Crete is mountainous, its character is defined by a high mountain range crossing from west to east, formed by three different groups of mountains: The White Mountains or Lefka Ori 2,454 m The Idi Range (Psiloritis 35.18°N 24.82°E / 35.18.
The island has a number of gorges, such as the Samariá Gorge, Imbros Gorge, Kourtaliotiko Gorge, Ha Gorge, Platania Gorge, the Gorge of the Dead and Richtis Gorge and waterfall at Exo Mouliana in Sitia. The rivers of Crete include the Ieropotamos River, the Koiliaris, the Anapodiaris, the Almiros, the Giofyros, Megas Potamos. There are only two freshwater lakes in Crete: Lake Kournas and Lake Agia, which are both in Chania regional unit. Lake Voulismeni at the coast, at Aghios Nikolaos, was a freshwater lake but is now connected to the sea, in Lasithi. Lakes that were created by dams exist in Crete. There are three: the lake of Aposelemis Dam, the lake of Potamos Dam, the lake of Mpramiana Dam. A large number of islands and rocks hug the coast of Crete. Many are visited by tourists, some are only visited by biologists; some are environmentally protected. A small sample of the islands includes: Gramvousa the pirate island opposite the Balo lagoon Elafonisi, which commemorates a shipwreck and an Ottoman massacre Chrysi island, which hosts the largest natural Lebanon cedar forest in Europe Paximadia island where the god Apollo and the goddess Artemis were born The Venetian fort and leper colony at Spinalonga opposite the beach and shallow waters of Elounda Dionysades islands which are in an environmentally protected region together the Palm Beach Forest of Vai in the municipality of Sitia, LasithiOff the south coast, the island of Gavdos is located 26 nautical miles south of Hora Sfakion and is the southernmost point of Europe.
Crete straddles two climatic zones, the Mediterranean and the North African falling within the former. As such, the climate in Crete is Mediterranean; the atmosphere can be quite humid, depending on the proximity to the sea, while winter is mild. Snowfall is rare in the low-lying areas. While some mountain tops are snow-capped for most of the year, near the coast snow only stays on the ground for a few minutes or hours. However, a exceptional cold snap swept the island in February 2004, during which period the whole island was blanketed with snow. During the Cretan summer, average temperatures reach the high 20s-low 30s Celsius, with maxima touching the upper 30s-mid 40s; the south coast, including the Mesara Pla
Sculpture is the branch of the visual arts that operates in three dimensions. It is one of the plastic arts. Durable sculptural processes used carving and modelling, in stone, ceramics and other materials but, since Modernism, there has been an complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded or cast. Sculpture in stone survives far better than works of art in perishable materials, represents the majority of the surviving works from ancient cultures, though conversely traditions of sculpture in wood may have vanished entirely. However, most ancient sculpture was brightly painted, this has been lost. Sculpture has been central in religious devotion in many cultures, until recent centuries large sculptures, too expensive for private individuals to create, were an expression of religion or politics; those cultures whose sculptures have survived in quantities include the cultures of the ancient Mediterranean and China, as well as many in Central and South America and Africa.
The Western tradition of sculpture began in ancient Greece, Greece is seen as producing great masterpieces in the classical period. During the Middle Ages, Gothic sculpture represented the agonies and passions of the Christian faith; the revival of classical models in the Renaissance produced famous sculptures such as Michelangelo's David. Modernist sculpture moved away from traditional processes and the emphasis on the depiction of the human body, with the making of constructed sculpture, the presentation of found objects as finished art works. A basic distinction is between sculpture in the round, free-standing sculpture, such as statues, not attached to any other surface, the various types of relief, which are at least attached to a background surface. Relief is classified by the degree of projection from the wall into low or bas-relief, high relief, sometimes an intermediate mid-relief. Sunk-relief is a technique restricted to ancient Egypt. Relief is the usual sculptural medium for large figure groups and narrative subjects, which are difficult to accomplish in the round, is the typical technique used both for architectural sculpture, attached to buildings, for small-scale sculpture decorating other objects, as in much pottery and jewellery.
Relief sculpture may decorate steles, upright slabs of stone also containing inscriptions. Another basic distinction is between subtractive carving techniques, which remove material from an existing block or lump, for example of stone or wood, modelling techniques which shape or build up the work from the material. Techniques such as casting and moulding use an intermediate matrix containing the design to produce the work; the term "sculpture" is used to describe large works, which are sometimes called monumental sculpture, meaning either or both of sculpture, large, or, attached to a building. But the term properly covers many types of small works in three dimensions using the same techniques, including coins and medals, hardstone carvings, a term for small carvings in stone that can take detailed work; the large or "colossal" statue has had an enduring appeal since antiquity. Another grand form of portrait sculpture is the equestrian statue of a rider on horse, which has become rare in recent decades.
The smallest forms of life-size portrait sculpture are the "head", showing just that, or the bust, a representation of a person from the chest up. Small forms of sculpture include the figurine a statue, no more than 18 inches tall, for reliefs the plaquette, medal or coin. Modern and contemporary art have added a number of non-traditional forms of sculpture, including sound sculpture, light sculpture, environmental art, environmental sculpture, street art sculpture, kinetic sculpture, land art, site-specific art. Sculpture is an important form of public art. A collection of sculpture in a garden setting can be called a sculpture garden. One of the most common purposes of sculpture is in some form of association with religion. Cult images are common in many cultures, though they are not the colossal statues of deities which characterized ancient Greek art, like the Statue of Zeus at Olympia; the actual cult images in the innermost sanctuaries of Egyptian temples, of which none have survived, were evidently rather small in the largest temples.
The same is true in Hinduism, where the simple and ancient form of the lingam is the most common. Buddhism brought the sculpture of religious figures to East Asia, where there seems to have been no earlier equivalent tradition, though again simple shapes like the bi and cong had religious significance. Small sculptures as personal possessions go back to the earliest prehistoric art, the use of large sculpture as public art to impress the viewer with the power of a ruler, goes back at least to the Great Sphinx of some 4,500 years ago. In archaeology and art history the appearance, sometimes disappearance, of large or monumental sculpture in a culture is regarded as of great significance, though tracing the emergence is complicated by the presumed existence of sculpture in wood and other perishable materials of which no record remains; the ability to s
