Integrated Authority File
The Integrated Authority File or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used for documentation in libraries and also by archives and museums; the GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero licence; the GND specification provides a hierarchy of high-level entities and sub-classes, useful in library classification, an approach to unambiguous identification of single elements. It comprises an ontology intended for knowledge representation in the semantic web, available in the RDF format; the Integrated Authority File became operational in April 2012 and integrates the content of the following authority files, which have since been discontinued: Name Authority File Corporate Bodies Authority File Subject Headings Authority File Uniform Title File of the Deutsches Musikarchiv At the time of its introduction on 5 April 2012, the GND held 9,493,860 files, including 2,650,000 personalised names.
There are seven main types of GND entities: LIBRIS Virtual International Authority File Information pages about the GND from the German National Library Search via OGND Bereitstellung des ersten GND-Grundbestandes DNB, 19 April 2012 From Authority Control to Linked Authority Data Presentation given by Reinhold Heuvelmann to the ALA MARC Formats Interest Group, June 2012
Geodesy, is the Earth science of measuring and understanding Earth's geometric shape, orientation in space, gravitational field. The field incorporates studies of how these properties change over time and equivalent measurements for other planets. Geodynamical phenomena include crustal motion and polar motion, which can be studied by designing global and national control networks, applying space and terrestrial techniques, relying on datums and coordinate systems; the word "geodesy" comes from the Ancient Greek word γεωδαισία geodaisia. It is concerned with positioning within the temporally varying gravity field. Geodesy in the German-speaking world is divided into "higher geodesy", concerned with measuring Earth on the global scale, "practical geodesy" or "engineering geodesy", concerned with measuring specific parts or regions of Earth, which includes surveying; such geodetic operations are applied to other astronomical bodies in the solar system. It is the science of measuring and understanding Earth's geometric shape, orientation in space, gravity field.
To a large extent, the shape of Earth is the result of rotation, which causes its equatorial bulge, the competition of geological processes such as the collision of plates and of volcanism, resisted by Earth's gravity field. This applies to the liquid surface and Earth's atmosphere. For this reason, the study of Earth's gravity field is called physical geodesy; the geoid is the figure of Earth abstracted from its topographical features. It is an idealized equilibrium surface of sea water, the mean sea level surface in the absence of currents and air pressure variations, continued under the continental masses; the geoid, unlike the reference ellipsoid, is irregular and too complicated to serve as the computational surface on which to solve geometrical problems like point positioning. The geometrical separation between the geoid and the reference ellipsoid is called the geoidal undulation, it varies globally between ± 110 m. A reference ellipsoid, customarily chosen to be the same size as the geoid, is described by its semi-major axis a and flattening f.
The quantity f = a − b/a, where b is the semi-minor axis, is a purely geometrical one. The mechanical ellipticity of Earth can be determined to high precision by observation of satellite orbit perturbations, its relationship with the geometrical flattening is indirect. The relationship depends on the internal density distribution, or, in simplest terms, the degree of central concentration of mass; the 1980 Geodetic Reference System posited a 1:298.257 flattening. This system was adopted at the XVII General Assembly of the International Union of Geodesy and Geophysics, it is the basis for geodetic positioning by the Global Positioning System and is thus in widespread use outside the geodetic community. The numerous systems that countries have used to create maps and charts are becoming obsolete as countries move to global, geocentric reference systems using the GRS 80 reference ellipsoid; the geoid is "realizable", meaning it can be located on Earth by suitable simple measurements from physical objects like a tide gauge.
The geoid can, therefore, be considered a real surface. The reference ellipsoid, has many possible instantiations and is not realizable, therefore it is an abstract surface; the third primary surface of geodetic interest—the topographic surface of Earth—is a realizable surface. The locations of points in three-dimensional space are most conveniently described by three cartesian or rectangular coordinates, X, Y and Z. Since the advent of satellite positioning, such coordinate systems are geocentric: the Z-axis is aligned with Earth's rotation axis. Prior to the era of satellite geodesy, the coordinate systems associated with a geodetic datum attempted to be geocentric, but their origins differed from the geocenter by hundreds of meters, due to regional deviations in the direction of the plumbline; these regional geodetic data, such as ED 50 or NAD 27 have ellipsoids associated with them that are regional "best fits" to the geoids within their areas of validity, minimizing the deflections of the vertical over these areas.
It is only because GPS satellites orbit about the geocenter, that this point becomes the origin of a coordinate system defined by satellite geodetic means, as the satellite positions in space are themselves computed in such a system. Geocentric coordinate systems used in geodesy can be divided into two classes: Inertial reference systems, where the coordinate axes retain their orientation relative to the fixed stars, or equivalently, to the rotation axes of ideal gyroscopes; the X-axis lies within the Greenwich observatory's meridian plane. The coordinate transformation between these two systems is described to good approximation by sidereal time, which takes into account variations in Earth's axial rotation. A more accurate description takes polar motion into account, a phenomenon monitored by geodesists. In surveying and mapping, important fields of application of geodesy, two general types of coordinate systems are used in the plane
Protestantism is the second largest form of Christianity with collectively between 800 million and more than 900 million adherents worldwide or nearly 40% of all Christians. It originated with the 16th century Reformation, a movement against what its followers perceived to be errors in the Roman Catholic Church. Protestants reject the Roman Catholic doctrine of papal supremacy and sacraments, but disagree among themselves regarding the real presence of Christ in the Eucharist, they emphasize the priesthood of all believers, justification by faith alone rather than by good works, the highest authority of the Bible alone in faith and morals. The "five solae" summarise basic theological differences in opposition to the Roman Catholic Church. Protestantism is popularly considered to have begun in Germany in 1517 when Martin Luther published his Ninety-five Theses as a reaction against abuses in the sale of indulgences by the Roman Catholic Church, which purported to offer remission of sin to their purchasers.
However, the term derives from the letter of protestation from German Lutheran princes in 1529 against an edict of the Diet of Speyer condemning the teachings of Martin Luther as heretical. Although there were earlier breaks and attempts to reform the Roman Catholic Church—notably by Peter Waldo, John Wycliffe, Jan Hus—only Luther succeeded in sparking a wider and modern movement. In the 16th century, Lutheranism spread from Germany into Denmark, Sweden, Latvia and Iceland. Reformed denominations spread in Germany, the Netherlands, Scotland and France by reformers such as John Calvin, Huldrych Zwingli, John Knox; the political separation of the Church of England from the pope under King Henry VIII began Anglicanism, bringing England and Wales into this broad Reformation movement. Protestants have developed their own culture, with major contributions in education, the humanities and sciences, the political and social order, the economy and the arts, many other fields. Protestantism is diverse, being more divided theologically and ecclesiastically than either the Roman Catholic Church, the Eastern Orthodox Church, or Oriental Orthodoxy.
Without structural unity or central human authority, Protestants developed the concept of an invisible church, in contrast to the Roman Catholic view of the Catholic Church as the visible one true Church founded by Jesus Christ. Some denominations do have a worldwide scope and distribution of membership, while others are confined to a single country. A majority of Protestants are members of a handful of Protestant denominational families: Adventists, Anglicans, Reformed, Lutherans and Pentecostals. Nondenominational, charismatic and other churches are on the rise, constitute a significant part of Protestant Christianity. Proponents of the branch theory consider Protestantism one of the three major divisions of Christendom, together with the Roman Catholic Church and Orthodoxy. Six princes of the Holy Roman Empire and rulers of fourteen Imperial Free Cities, who issued a protest against the edict of the Diet of Speyer, were the first individuals to be called Protestants; the edict reversed concessions made to the Lutherans with the approval of Holy Roman Emperor Charles V three years earlier.
The term protestant, though purely political in nature acquired a broader sense, referring to a member of any Western church which subscribed to the main Protestant principles. However, it is misused to mean any church outside the Roman and Eastern Orthodox communions. Protestantism as a general term is now used in contradistinction to the other major Christian traditions, i.e. Roman Catholicism and Orthodoxy. During the Reformation, the term protestant was hardly used outside of German politics. People who were involved in the religious movement used the word evangelical. For further details, see the section below. Protestant became a general term, meaning any adherent of the Reformation in the German-speaking area, it was somewhat taken up by Lutherans though Martin Luther himself insisted on Christian or evangelical as the only acceptable names for individuals who professed Christ. French and Swiss Protestants instead preferred the word reformed, which became a popular and alternative name for Calvinists.
The word evangelical, which refers to the gospel, was used for those involved in the religious movement in the German-speaking area beginning in 1517. Nowadays, evangelical is still preferred among some of the historical Protestant denominations in the Lutheran and United Protestant traditions in Europe, those with strong ties to them. Above all the term is used by Protestant bodies in the German-speaking area, such as the Evangelical Church in Germany. In continental Europe, an Evangelical is either a Calvinist, or a United Protestant; the German word evangelisch means Protestant, is different from the German evangelikal, which refers to churches shaped by Evangelicalism. The English word evangelical refers to evangelical Protestant churches, therefore to a certain part of Protestantism rather than to Protestantism as a whole; the English word traces its roots back to the Puritans in England, where Evangelicalism originated, was brought to the United States. Martin Luther always disliked the term Lutheran, preferring the term evangelical, derived from euangelion, a Greek word meaning "good news", i.e. "gospel".

Montpellier is a city near the south coast of France on the Mediterranean Sea. It is the capital of the Hérault department, it is located in the Occitanie region. In 2016, 607,896 people lived in 281,613 in the city itself. Nearly one third of the population are students from three universities and from three higher education institutions that are outside the university framework in the city. Montpellier is the third-largest French city on the Mediterranean coast after Nice, it is the 7th-largest city of France, is the fastest-growing city in the country over the past 25 years. In the Early Middle Ages, the nearby episcopal town of Maguelone was the major settlement in the area, but raids by pirates encouraged settlement a little further inland. Montpellier, first mentioned in a document of 985, was founded under a local feudal dynasty, the Guilhem, who combined two hamlets and built a castle and walls around the united settlement; the two surviving towers of the city walls, the Tour des Pins and the Tour de la Babotte, were built around the year 1200.
Montpellier came to prominence in the 12th century—as a trading centre, with trading links across the Mediterranean world, a rich Jewish cultural life that flourished within traditions of tolerance of Muslims and Cathars—and of its Protestants. William VIII of Montpellier gave freedom for all to teach medicine in Montpellier in 1180; the city's faculties of law and medicine were established in 1220 by Cardinal Conrad of Urach, legate of Pope Honorius III. This era marked the high point of Montpellier's prominence; the city became a possession of the Kings of Aragon in 1204 by the marriage of Peter II of Aragon with Marie of Montpellier, given the city and its dependencies as part of her dowry. Montpellier gained a charter in 1204 when Peter and Marie confirmed the city's traditional freedoms and granted the city the right to choose twelve governing consuls annually. Under the Kings of Aragon, Montpellier became a important city, a major economic centre and the primary centre for the spice trade in the Kingdom of France.
It was the second or third most important city of France at that time, with some 40,000 inhabitants before the Black Death. Montpellier remained a possession of the crown of Aragon until it passed to James III of Majorca, who sold the city to the French king Philip VI in 1349, to raise funds for his ongoing struggle with Peter IV of Aragon. In the 14th century, Pope Urban VIII gave Montpellier a new monastery dedicated to Saint Peter, noteworthy for the unusual porch of its chapel, supported by two high, somewhat rocket-like towers. With its importance increasing, the city gained a bishop, who moved from Maguelone in 1536, the huge monastery chapel became a cathedral. In 1432, Jacques Cœur established himself in the city and it became an important economic centre, until 1481 when Marseille overshadowed it in this role. At the time of the Reformation in the 16th century, many of the inhabitants of Montpellier became Protestants and the city became a stronghold of Protestant resistance to the Catholic French crown.
In 1622, King Louis XIII besieged the city which surrendered after a two months siege, afterwards building the Citadel of Montpellier to secure it. Louis XIV made Montpellier capital of Bas Languedoc, the town started to embellish itself, by building the Promenade du Peyrou, the Esplanade and a large number of houses in the historic centre. After the French Revolution, the city became the capital of the much smaller Hérault. During the 19th century the city thrived on the wine culture that it was able to produce due to the abundance of sun throughout the year; the wine consumption in France allowed Montpellier's citizens to become wealthy until in the 1890's a fungal disease had spread amongst the vineyards and the people were no longer able to grow the grapes needed for wine. After this the city had grown because it welcomed immigrants from Algeria and other parts of northern Africa after Algeria's independence from France. In the 21st century Montpellier is between 8th largest city; the city had another influx in population more largely due to the student population, who make up about one-third of Montpellier's population.
The school of medicine is what kickstarted the city's thriving university culture,however many other universities have been well established in the coastal city that has developments such as the Corum and the Antigone that too have been drawing in more and more students.

Montpellier's highest point is the Place du Peyrou, at an altitude of 57 m; the city is built on two hills and Montpelliéret, thus some o
England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England and made popular by its use in Arthurian legend; the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximate
Florida is the southernmost contiguous state in the United States. The state is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Atlantic Ocean, to the south by the Straits of Florida. Florida is the 22nd-most extensive, the 3rd-most populous, the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and the largest city by area in the contiguous United States; the Miami metropolitan area is Florida's most populous urban area. Tallahassee is the state's capital. Florida's $1.0 trillion economy is the fourth largest in the United States. If it were a country, Florida would be the 16th largest economy in the world, the 58th most populous as of 2018. In 2017, Florida's per capita personal income was ranking 26th in the nation; the unemployment rate in September 2018 was 3.5% and ranked as the 18th in the United States. Florida exports nearly $55 billion in goods made in the 8th highest among all states.
The Miami Metropolitan Area is by far the largest urban economy in Florida and the 12th largest in the United States with a GDP of $344.9 billion as of 2017. This is more than twice the number of the next metro area, the Tampa Bay Area, which has a GDP of $145.3 billion. Florida is home to 51 of the world's billionaires with most of them residing in South Florida; the first European contact was made in 1513 by Spanish explorer Juan Ponce de León, who called it la Florida upon landing there in the Easter season, known in Spanish as Pascua Florida. Florida was a challenge for the European colonial powers before it gained statehood in the United States in 1845, it was a principal location of the Seminole Wars against the Native Americans, racial segregation after the American Civil War. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, as well as for its increasing environmental issues; the state's economy relies on tourism and transportation, which developed in the late 19th century.
Florida is renowned for amusement parks, orange crops, winter vegetables, the Kennedy Space Center, as a popular destination for retirees. Florida is the flattest state in the United States. Lake Okeechobee is the largest freshwater lake in the U. S. state of Florida. Florida's close proximity to the ocean influences many aspects of daily life. Florida is a reflection of multiple inheritance. Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, continues to attract celebrities and athletes, it is internationally known for golf, auto racing, water sports. Several beaches in Florida have emerald-colored coastal waters. About two-thirds of Florida occupies a peninsula between the Gulf of the Atlantic Ocean. Florida has the longest coastline in the contiguous United States 1,350 miles, not including the contribution of the many barrier islands. Florida has a total of 4,510 islands; this is the second-highest number of islands of any state of the United States.
It is the only state that borders both the Gulf of the Atlantic Ocean. Much of the state is characterized by sedimentary soil. Florida has the lowest high point of any U. S. state. The climate varies from subtropical in the north to tropical in the south; the American alligator, American crocodile, American flamingo, Roseate spoonbill, Florida panther, bottlenose dolphin, manatee can be found in Everglades National Park in the southern part of the state. Along with Hawaii, Florida is one of only two states that has a tropical climate, is the only continental state with either a tropical climate or a coral reef; the Florida Reef is the only living coral barrier reef in the continental United States, the third-largest coral barrier reef system in the world. By the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee of the Florida Panhandle, the Timucua of northern and central Florida, the Ais of the central Atlantic coast, the Tocobaga of the Tampa Bay area, the Calusa of southwest Florida and the Tequesta of the southeastern coast.
Florida was the first region of the continental United States to be visited and settled by Europeans. The earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2, 1513, he named the region Florida. The story that he was searching for the Fountain of Youth is mythical and only appeared long after his death. In May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land, he described seeing a thick wall of red mangroves spread mile after mile, some reaching as high as 70 feet, with intertwined and elevated roots making landing difficult. The Spanish introduced Christianity, horses, the Castilian language, more to Florida. Spain established several settlements with varying degrees of success. In 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561.
In 1565, the settlement of St. Augustine was established under the leadership of admiral and
The Cévennes is a cultural region and range of mountains in south-central France, on the south-east edge of the Massif Central. It covers parts of the départements of Gard, Hérault and Lozère. Rich in geographical and cultural significance, portions of the region are protected within the Cévennes National Park, the Cévennes Biosphere Reserve, as well as the Causses and the Cévennes, Mediterranean agro-pastoral Cultural Landscape; the area has been inhabited since 400,000 BCE and has numerous megaliths which were erected beginning around 2500 BCE. The name Cévennes comes from the Gaulish Cebenna; as of 1999, there were 165,707 inhabitants in the region, with 20,847 living inside the UNESCO protected zone. Inhabitants of the region are known as Cévenols, from the adjective Cévenol Too poor to host cities, too rich to be abandoned, the landscape of Causses and Cévennes are the result of the modification of the natural environment by agro-pastoral systems over a millennium; the Causses and Cévennes demonstrate every type of pastoral organisation to be found around the Mediterranean The mountain range gives its name to a meteorological effect when cold air from the Atlantic coast meets warm air of southern winds from the Mediterranean and causes heavy autumnal downpours leading to floods.
These are called épisodes cévenols. The origin of the name Cévennes is Celtic, coming from the Gaulish Cebenna, Latinized by Julius Caesar to Cevenna; the Cévennes are named Cemmenon in Strabo's Geographica. The word in Gaulish meant ridgeline and is related to the Breton word kein meaining back; the -vennes part of the name is related to the Gaelic word beinn meaning mountain or hill. There are several popular false etymologies, one of, that the name is derived for the words seven veins, supposed to be a reference to the seven rivers flowing through the region. Historical references to the name that predate the French Language itself, preclude this possibility. Another false etymology suggests that the name comes from the occitan word ceba which means « onion », supposed to reference the layered structure of slate which makes up the mountains, but this isn't possible as the occitan ceba derives from latin cepa which does not phonetically fit the references to the region in Latin and Greek Literature.
Additionally, the suffix -enna Celtic was brought over into latin, was never used for words of Latin Origin. In the larger sense, the Cevennes include 9 départements: le Tarn, l'Aude, l'Hérault, l'Aveyron, le Gard, la Lozère, l'Ardèche, le Rhône et la Loire. More the Cevennes encompasses the Lozère and the Gard; the Parc national des Cévennes is entirely within Lozère. The principal towns and villages of the Cevennes are Alès, Le Vigan, Sumène, Ganges, Saint-Hippolyte-du-Fort, Lasalle, Saint-André-de-Valborgne, Saint-Jean-du-Gard, Florac, Saint-Germain-de-Calberte, le Pont-de-Montvert, Villefort, Génolhac, Bessèges, Saint-Ambroix, Gagnières, Les Vans, Mende; the Cévennes mountains run from southwest to northeast, with the highest point being the Mont Lozère. The Mont Aigoual is on the border of two departments; the Loire and Allier flowing towards the Atlantic Ocean, as well as the Ardèche and tributary Chassezac, Cèze, the different rivers Gardons to the Rhône, Vidourle, Hérault and Dourbie that flow to the Mediterranean Sea, have their headwaters in the Cévennes.
Cévennes National Park was created in the region in 1970 and the Parc Naturel Régional des Monts d'Ardèche preserves some of the natural areas. Two canyons are near the region: the Gorges du Tarn; this is a socio-economic marginal region, while bio-geographically, there is altitudinal stratification and a gradient between the mountainous centre and the mediterranean littoral ecologies. The Cévennes form the south eastern fragment of the Massif Central, separated from the related Montagnes Noires by the limestone Causses; the basement rocks of Granites and Schistes were uplifted by the Variscan Orogeny forming a discontinuity, with the subsequent erosion infilling the lower voids for much of Permian and Triassic period, while changing sea levels added a thick limestone covering, with only the tops of the Cévennes protruding as islands in the Jurassic sea. This in turn was eroded, The Cévennes forms the watershed between the Mediterranean. In late Cretaceous and early Tertiary times further mountain building occurred.
The Alpine orogeny lifted and deformed the Alps and the Pyrenees though the Massif Central acted as a rigid block, the cover rocks remained horizontal. Some have been folded through faulting at the time of the opening of the western Mediterranean in Tertiary times; the principal rivers of the region have cut into the limestone forming deep gorges: Gorges du Tarn, Gorges de la Jonte, Gorges de l'Ardèche, Cèze etc. "Before silk, before Calvin, a prehistory" Transhumance is most the beginning of human activity in the Cevennes but little trace has been found of humans from the Paleolithic era except in the southern portion around Ganges and Saint-Hippolyte-du-Fort which contains a large quantity of caves rich with archeological evidence such as "La Roque Aynier", "Baume Dolente" which suggest the presence of Magdalenian peoples. By the Neolithic epoch, which lasted from about 12,000 BCE to around 2,300 BCE in France and hunting were prevalent throughout the entire Cevennes with developments such as pottery moving from south to north in the regi
