France the French Republic, is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories. The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea, from the Rhine to the Atlantic Ocean, it is bordered by Belgium and Germany to the northeast and Italy to the east, Andorra and Spain to the south. The overseas territories include French Guiana in South America and several islands in the Atlantic and Indian oceans; the country's 18 integral regions span a combined area of 643,801 square kilometres and a total population of 67.3 million. France, a sovereign state, is a unitary semi-presidential republic with its capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban areas include Lyon, Toulouse, Bordeaux and Nice. During the Iron Age, what is now metropolitan France was inhabited by a Celtic people. Rome annexed the area in 51 BC, holding it until the arrival of Germanic Franks in 476, who formed the Kingdom of Francia.
The Treaty of Verdun of 843 partitioned Francia into Middle Francia and West Francia. West Francia which became the Kingdom of France in 987 emerged as a major European power in the Late Middle Ages following its victory in the Hundred Years' War. During the Renaissance, French culture flourished and a global colonial empire was established, which by the 20th century would become the second largest in the world; the 16th century was dominated by religious civil wars between Protestants. France became Europe's dominant cultural and military power in the 17th century under Louis XIV. In the late 18th century, the French Revolution overthrew the absolute monarchy, established one of modern history's earliest republics, saw the drafting of the Declaration of the Rights of Man and of the Citizen, which expresses the nation's ideals to this day. In the 19th century, Napoleon established the First French Empire, his subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a tumultuous succession of governments culminating with the establishment of the French Third Republic in 1870.
France was a major participant in World War I, from which it emerged victorious, was one of the Allies in World War II, but came under occupation by the Axis powers in 1940. Following liberation in 1944, a Fourth Republic was established and dissolved in the course of the Algerian War; the Fifth Republic, led by Charles de Gaulle, remains today. Algeria and nearly all the other colonies became independent in the 1960s and retained close economic and military connections with France. France has long been a global centre of art and philosophy, it hosts the world's fourth-largest number of UNESCO World Heritage Sites and is the leading tourist destination, receiving around 83 million foreign visitors annually. France is a developed country with the world's sixth-largest economy by nominal GDP, tenth-largest by purchasing power parity. In terms of aggregate household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, human development.
France is considered a great power in global affairs, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a leading member state of the European Union and the Eurozone, a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, La Francophonie. Applied to the whole Frankish Empire, the name "France" comes from the Latin "Francia", or "country of the Franks". Modern France is still named today "Francia" in Italian and Spanish, "Frankreich" in German and "Frankrijk" in Dutch, all of which have more or less the same historical meaning. There are various theories as to the origin of the name Frank. Following the precedents of Edward Gibbon and Jacob Grimm, the name of the Franks has been linked with the word frank in English, it has been suggested that the meaning of "free" was adopted because, after the conquest of Gaul, only Franks were free of taxation.
Another theory is that it is derived from the Proto-Germanic word frankon, which translates as javelin or lance as the throwing axe of the Franks was known as a francisca. However, it has been determined that these weapons were named because of their use by the Franks, not the other way around; the oldest traces of human life in what is now France date from 1.8 million years ago. Over the ensuing millennia, Humans were confronted by a harsh and variable climate, marked by several glacial eras. Early hominids led a nomadic hunter-gatherer life. France has a large number of decorated caves from the upper Palaeolithic era, including one of the most famous and best preserved, Lascaux. At the end of the last glacial period, the climate became milder. After strong demographic and agricultural development between the 4th and 3rd millennia, metallurgy appeared at the end of the 3rd millennium working gold and bronze, iron. France has numerous megalithic sites from the Neolithic period, including the exceptiona
The Vulgate is a late-4th-century Latin translation of the Bible that became the Catholic Church's promulgated Latin version of the Bible during the 16th century. The translation was the work of Jerome, who in 382 had been commissioned by Pope Damasus I to revise the Vetus Latina Gospels in use by the Roman Church. Jerome, on his own initiative, extended this work of revision and translation to include most of the books of the Bible, once published, the new version was adopted and eclipsed the Vetus Latina; the Catholic Church affirmed the Vulgate as its official Latin Bible at the Council of Trent, though there was no authoritative edition at that time. The Clementine edition of the Vulgate of 1592 became the standard Bible text of the Roman Rite of the Catholic Church and remained so until 1979 when the Nova Vulgata was promulgated; the Vulgate has a compound text, not the work of Jerome. While Jerome revised all the Gospels of the Vetus Latina from the Greek, it is unknown who revised the rest of the New Testament.
Several unrevised books of the Vetus Latina Old Testament commonly became included in the Vulgate. Medieval Vulgate Bibles might further include the Prayer of Manasses, 4 Esdras, the Epistle to the Laodiceans and Psalm 151. Jerome himself translated all books of the Jewish Bible from Hebrew; the Vulgate's components include: Independent translation from the Hebrew by Jerome: the books of the Hebrew Bible, including a translation of the Psalms from the Hebrew, found in early medieval Vulgate manuscripts but is supplanted by Jerome's Gallican version in bibles. This was completed in 405. Free translation from a secondary Aramaic version by Jerome: Tobias and Judith. Translation from the Greek of Theodotion by Jerome: The three additions to the Book of Daniel; the Song of the Three Children was retained within the narrative of Daniel, Susanna was moved by Jerome from before the beginning of Daniel to the end of the book along with Bel and the Dragon. These additions he marked with an obelus to distinguish them from the canonical text.
Translation from the Common Septuagint by Jerome: the Additions to Esther. Jerome gathered all these additions together at the end of the Book of Esther, marking them with an obelus. Translation from the Hexaplar Septuagint by Jerome: his Gallican version of the Book of Psalms. Jerome's Hexaplaric revisions of other books of Old Testament continued to circulate in Italy for several centuries, but only Job and fragments of other books survive. Revision of the Old Latin by Jerome: the Gospels, corrected with reference to the best Greek manuscripts Jerome considered available. Revision of the Old Latin: the Roman Psalter including Psalm 151, undertaken prior to Jerome but continuing in liturgical use, included in many medieval Vulgate Old Testaments and liturgical psalters. Revision of the Old Latin by a person or persons unknown, contemporary with Jerome: Acts, Pauline epistles, Catholic epistles and the Apocalypse. Old Latin, wholly unrevised: Epistle to the Laodiceans, Prayer of Manasses, 4 Esdras, Ecclesiasticus, 1 and 2 Maccabees.
The Book of Baruch and the Letter of Jeremiah were excluded by Jerome as non-canonical, but sporadically re-admitted into the Vulgate tradition from the Additions to the Book of Jeremiah of the Old Latin from the 9th century onwards. Independent translation, distinct from the Old Latin, he had been commissioned by Damasus I in 382 to revise the Old Latin text of the four Gospels from the best Greek texts. By the time of Damasus' death in 384, Jerome had completed this task, together with a more cursory revision from the Greek Common Septuagint of the Old Latin text of the Psalms in the Roman Psalter, a version which he disowned and is now lost. How much of the rest of the New Testament he revised is difficult to judge today, but none of his work survived in the Vulgate text of these books; the revised text of the New Testament outside the Gospels is the work of one or more other scholars. This unknown reviser worked more than Jerome had done using older Greek manuscript sources of Alexandrian text-type, had published a complete revised New Testament text by 410 at the latest, when Pelagius quoted from it in his commentary on the letters of Paul.
In 385, Jerome was forced out of Rome and settled in Bethlehem. There he was able to use a surviving manuscript of the Hexapla from the nearby Theological Library of Caesarea Maritima, a column
Muséum de Toulouse
The Muséum de Toulouse, Muséum d'Histoire Naturelle de la ville de Toulouse is a museum of natural history in Toulouse, France. It is located in the Busca-Montplaisir, houses a collection of more than 2.5 million items and has some 3 000 square metres of exhibition space. Its Index Herbariorum code is TLM; the museum was founded in 1796 by the naturalist Philippe-Isidore Picot de Lapeyrouse, with his collections being able to be housed in the former Carmelite monastery in Toulouse. In 1808, the emperor Napoleon formally gifted all the Carmelite buildings and land to the city of Toulouse, in 1865 the museum was opened to the public in its present location and under the directorship of Édouard Filhol. Toulouse museum was the first museum in the world to open a gallery of prehistory thanks to the collaboration of Émile Cartailhac, Jean-Baptiste Noulet, Eugène Trutat. In 1887 the botanical gardens of the university of Toulouse became part of the museum. In 2008, the museum reopened in its present form with the renovations and extensions of the museum, designed by the architectural firm of Jean-Paul Viguier, having been completed.
The permanent exhibition has five linked themes: Sequence 1: Feeling the Earth's power. Nature of the solar system and its formation. Nature of the Earth – plate tectonics and volcanic activity and erosion and mineralogy. Sequence 2: Doing away with our notions of hierarchy; the nature of life – biodiversity and organization. Sequence 3: Getting to grips with the huge scale. Earth history from 3.8 billion years ago. Introduces time and the evolution of life Sequence 4: Admitting the obvious; the main functions of living beings—feeding, locomotion, reproduction and communication. Sequence 5: Inventing the future; the impact of human activity—demographic pressure on ecosystems and natural resources This section presents examples to illustrate the content of each different collection of the Museum de Toulouse. The prehistoric collection includes artefacts excavated in France, they contain comparative material from other parts of Europe and other continents. Notable collectors include Édouard Harlé, Antoine Meillet, Alexis Damour, Félix Regnault, Louis Péringuey, Émile Cartailhac, Daniel Bugnicourt, Edward John Dunn, Henri Breuil, Louis Lartet, as well as the curators Jean-Baptiste Noulet, Eugène Trutat, Édouard Filhol.
The herbarium contains historic specimens collected by Benjamin Balansa. The bird collection of MHNT contains more than 30,000 specimens. About 8,500 bird mounts and 1,500 scientific bird skins are included. Other bird items are around 5,300 eggs; the collection focuses on Europe, but the collection has exotic species. Most are documented on computer systems; the bird mount collection of Victor Besaucèle, with 5,000 specimens, is one of the most important historic collections in Europe. Other collectors represented are R. Bourret, G. Cossaune, M. Gourdon, Hammonville, A. Lacroix, Reboussin; the egg collection of Jacques Perrin de Brichambaut was acquired in 2010. It contains his personal collections, supplemented by those of other ornithologists, notably Georges Guichard, Henri Heim de Balsac, Rene de Naurois, it includes all the palearctic species, about 1,000 species and nearly 15,000 eggs, is one of the most complete and best-documented palearctic egg collections in Europe. The specimens of the collection of paleontology amount to tens of thousands.
They date from the Paleoarchean to the Eocene. Henri Gaussen was botanist; the botanic garden which honours his name is attached to the museum and is part of the Earth and Life Science Research and Training Paul Sabatier University. A second botanical area, The Museum Gardens, extends over 3 hectares, it is notable for "potagers du monde" and a "shade house" which recreates the conditions required by shade plants.

The semipalmated plover is a small plover. The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate, it derives from Ancient Greek kharadrios a bird found in ravines and river valleys. The specific semipalmatus is Latin and comes from semi, "half" and palma, "palm". Like the English name, this refers to its only webbed feet; this species weighs 22 -- measures 14 -- 20 cm in length and 35 -- 56 cm across the wings. Adults have a grey-brown back and wings, a white belly, a white breast with one black neckband, they have a brown cap, a white forehead, a black mask around the eyes and a short orange and black bill. Their breeding habitat is open ground on flats across northern Canada and Alaska, they nest on the ground in an open area with no plant growth. They are migratory and winter in coastal areas of the southern United States, the Caribbean and much of South America, they are rare vagrants to western Europe, have been found in Tierra del Fuego and the Isles of Scilly.
Their true status may be obscured by the difficulty in identifying them from the similar ringed plover of Eurasia, of which it was considered a subspecies. Semipalmated plovers forage for food on beaches, tidal flats and fields by sight, they eat insects and worms. This bird resembles the killdeer but has only one band. Since the semipalmated plover nests on the ground, it uses a "broken-wing" display to lure intruders away from the nest, in a display similar to the related killdeer.

Late Latin is the scholarly name for the written Latin of late antiquity. English dictionary definitions of Late Latin date this period from the 3rd to the 6th centuries AD, continuing into the 7th century in the Iberian Peninsula; this somewhat ambiguously defined version of Latin was used between the eras of Classical Latin and Medieval Latin. There is no scholarly consensus about when Classical Latin should end or Medieval Latin should begin. However, Late Latin is characterized by an identifiable style. Being a written language, Late Latin is not the same as Vulgar Latin; the latter served as ancestor of the Romance languages. Although Late Latin reflects an upsurge of the use of Vulgar Latin vocabulary and constructs, it remains classical in its overall features, depending on the author who uses it; some Late Latin writings are more literary and classical, but others are more inclined to the vernacular. Late Latin is not identical to Christian patristic Latin, used in the theological writings of the early Christian fathers.
While Christian writings used a subset of Late Latin, pagans wrote extensively in Late Latin in the early part of the period. Late Latin formed when mercenaries from non-Latin-speaking peoples on the borders of the empire were being subsumed and assimilated in large numbers, the rise of Christianity was introducing a heightened divisiveness in Roman society, creating a greater need for a standard language for communicating between different socioeconomic registers and separated regions of the sprawling empire. A new and more universal speech evolved from the main elements: Classical Latin, Christian Latin, which featured sermo humilis in which the people were to be addressed, all the various dialects of Vulgar Latin; the linguist Antoine Meillet wrote, "Without the exterior appearance of the language being much modified, Latin became in the course of the imperial epoch a new language", and, "Serving as some sort of lingua franca to a large empire, Latin tended to become simpler, to keep above all what it had of the ordinary".
Neither Late Latin nor Late Antiquity are modern concepts. A notice in Harper's New Monthly Magazine of the publication of Andrews' Freund's Lexicon of the Latin Language in 1850 mentions that the dictionary divides Latin into ante-classic, quite classic, Augustan, post-Augustan and post-classic or late Latin, which indicates the term was in professional use by English classicists in the early 19th century. Instances of English vernacular use of the term may be found from the 18th century; the term Late Antiquity meaning post-classical and pre-medieval had currency in English well before then. Wilhelm Sigismund Teuffel's first edition of History of Roman Literature defined an early period, the Golden Age, the Silver Age and goes on to define other ages first by dynasty and by century. In subsequent editions he subsumed all periods under three headings: the First Period, the Second Period and the Third Period, "the Imperial Age", subdivided into the Silver Age, the 2nd century, Centuries 3–6 together, a recognition of Late Latin, as he sometimes refers to the writings of those times as "late."
Imperial Latin went on into English literature. There are, insoluble problems with the beginning and end of Imperial Latin. Politically the excluded Augustan Period is the paradigm of imperiality, yet the style cannot be bundled with either the Silver Age or with Late Latin. Moreover, in 6th century Italy, the Roman Empire no longer existed. Subsequently the term Imperial Latin was dropped by historians of Latin literature, although it may be seen in marginal works; the Silver Age was extended the final four centuries represent Late Latin. Low Latin is a vague and pejorative term that might refer to any post-classical Latin from Late Latin through Renaissance Latin depending on the author, its origins are obscure but the Latin expression media et infima Latinitas sprang into public notice in 1678 in the title of a Glossary by Charles du Fresne, sieur du Cange. The multi-volume set had many expansions by other authors subsequently; the title varies somewhat. It has been translated by expressions of different meanings.
The uncertainty is understanding what media, "middle", infima, "low", mean in this context. The media is securely connected to Medieval Latin by Cange's own terminology expounded in the Praefatio, such as scriptores mediae aetatis, "writers of the middle age." Cange's Glossary takes words from authors ranging from the Christian period to the Renaissance, dipping into the classical period if a word originated there. Either media et infima Latinitas refers to one age, which must be the middle age covering the entire post-classical range, or it refers to two consecutive periods, infima Latinitas and media Latinitas. Both interpretations have their adherents. In the former case the infimae appears extraneous; the two-period case postulates a second unity of style, infima Latinitas, translated into English as "Low Latin". Cange in the glossarial part of his Glossary identifies some words as being used by purioris Latinitatis scriptores, such as Cicero, he has said in the Preface that he rejects the a
Norfolk is a county in East Anglia in England. It borders Lincolnshire to the northwest, Cambridgeshire to the west and southwest, Suffolk to the south, its northern and eastern boundaries are the North Sea and, to the north-west, The Wash. The county town is Norwich. With an area of 2,074 square miles and a population of 859,400, Norfolk is a rural county with a population density of 401 per square mile. Of the county's population, 40% live in four major built up areas: Norwich, Great Yarmouth, King's Lynn and Thetford; the Broads is a network of lakes in the east of the county, extending south into Suffolk. The area is not a national park, it has similar status to a national park, is protected by the Broads Authority. Norfolk was settled in pre-Roman times, with camps along the higher land in the west, where flints could be quarried. A Brythonic tribe, the Iceni, inhabited the county from the 1st century BC to the end of the 1st century AD; the Iceni revolted against the Roman invasion in AD 47, again in 60 led by Boudica.
The crushing of the second rebellion opened the county to the Romans. During the Roman era roads and ports were constructed throughout the county and farming was widespread. Situated on the east coast, Norfolk was vulnerable to invasions from Scandinavia and Northern Europe, forts were built to defend against the Angles and Saxons. By the 5th century the Angles, after whom East Anglia and England itself are named, had established control of the region and became the "north folk" and the "south folk", hence, "Norfolk" and "Suffolk". Norfolk and several adjacent areas became the kingdom of East Anglia, which merged with Mercia and with Wessex; the influence of the Early English settlers can be seen in the many place names ending in "-ton" and "-ham". Endings such as "-by" and "-thorpe" are common, indicating Danish place names: in the 9th century the region again came under attack, this time from Danes who killed the king, Edmund the Martyr. In the centuries before the Norman Conquest the wetlands of the east of the county began to be converted to farmland, settlements grew in these areas.
Migration into East Anglia must have been high: by the time of the Domesday Book survey it was one of the most densely populated parts of the British Isles. During the high and late Middle Ages the county developed arable woollen industries. Norfolk's prosperity at that time is evident from the county's large number of medieval churches: out of an original total of over one thousand, 659 have survived, more than in the whole of the rest of Great Britain; the economy was in decline by the time of the Black Death, which reduced the population in 1349. By the 16th century Norwich had grown to become the second-largest city in England, but over one-third of its population died in the plague epidemic of 1579, in 1665 the Great Plague again killed around one-third of the population. During the English Civil War Norfolk was Parliamentarian; the economy and agriculture of the region declined somewhat. During the Industrial Revolution Norfolk developed little industry except in Norwich, a late addition to the railway network.
In the 20th century the county developed a role in aviation. The first development in airfields came with the First World War. For the local army regiments the Royal Norfolk Regiment and the Norfolk Yeomanry please click on the links. During the Second World War agriculture intensified, it has remained intensive since, with the establishment of large fields for growing cereals and oilseed rape. Norfolk's low-lying land and eroded cliffs, many of which are composed of chalk and clay, make it vulnerable to weathering by the sea; the most recent major erosion event occurred during the North Sea flood of 1953. The low-lying section of coast between Kelling and Lowestoft Ness in Suffolk is managed by the British Environment Agency to protect the Broads from sea flooding. Management policy for the North Norfolk coastline is described in the "North Norfolk Shoreline Management Plan" published in 2006, but has yet to be accepted by local authorities; the Shoreline Management Plan states that the stretch of coast will be protected for at least another 50 years, but that in the face of sea level rise and post-glacial lowering of land levels in the South East, there is an urgent need for further research to inform future management decisions, including the possibility that the sea defences may have to be realigned to a more sustainable position.
Natural England have contributed some research into the impacts on the environment of various realignment options. The draft report of their research was leaked to the press, who created great anxiety by reporting that Natural England plan to abandon a large section of the Norfolk Broads and farmland to the sea to save the rest of the Norfolk coastline from the impact of climate change. In 1998 Norfolk had a Gross Domestic Product of £9,319 million, which represents 1.5% of England's economy and 1.25% of the United Kingdom's economy. The GDP per head was £11,825, compared to £13,635 for East Anglia, £12,845 for England and £12,438 for the United Kingdom. In 1999–2000 the county had an unemployment rate of 5.6%, compared to 5.8% for England and 6.0% for the UK. Data from 2017 provided a useful update on the county's economy; the median hourly gross pay was £12.17 and the median weekly pay was £496.80. The employm
A chordate is an animal constituting the phylum Chordata. During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, a post-anal tail: these five anatomical features define this phylum. Chordates are bilaterally symmetric; the Chordata and Ambulacraria together form the superphylum Deuterostomia. Chordates are divided into three subphyla: Vertebrata. There are extinct taxa such as the Vetulicolia. Hemichordata has been presented as a fourth chordate subphylum, but now is treated as a separate phylum: hemichordates and Echinodermata form the Ambulacraria, the sister phylum of the Chordates. Of the more than 65,000 living species of chordates, about half are bony fish that are members of the superclass Osteichthyes. Chordate fossils have been found from as early as the Cambrian explosion, 541 million years ago. Cladistically, vertebrates - chordates with the notochord replaced by a vertebral column during development - are considered to be a subgroup of the clade Craniata, which consists of chordates with a skull.
The Craniata and Tunicata compose the clade Olfactores. Chordates form a phylum of animals that are defined by having at some stage in their lives all of the following anatomical features: A notochord, a stiff rod of cartilage that extends along the inside of the body. Among the vertebrate sub-group of chordates the notochord develops into the spine, in wholly aquatic species this helps the animal to swim by flexing its tail. A dorsal neural tube. In fish and other vertebrates, this develops into the spinal cord, the main communications trunk of the nervous system. Pharyngeal slits; the pharynx is the part of the throat behind the mouth. In fish, the slits are modified to form gills, but in some other chordates they are part of a filter-feeding system that extracts particles of food from the water in which the animals live. Post-anal tail. A muscular tail that extends backwards behind the anus. An endostyle; this is a groove in the ventral wall of the pharynx. In filter-feeding species it produces mucus to gather food particles, which helps in transporting food to the esophagus.
It stores iodine, may be a precursor of the vertebrate thyroid gland. There are soft constraints that separate chordates from certain other biological lineages, but are not part of the formal definition: All chordates are deuterostomes; this means. All chordates are based on a bilateral body plan. All chordates are coelomates, have a fluid filled body cavity called a coelom with a complete lining called peritoneum derived from mesoderm; the following schema is from the third edition of Vertebrate Palaeontology. The invertebrate chordate classes are from Fishes of the World. While it is structured so as to reflect evolutionary relationships, it retains the traditional ranks used in Linnaean taxonomy. Phylum Chordata †Vetulicolia? Subphylum Cephalochordata – Class Leptocardii Clade Olfactores Subphylum Tunicata – Class Ascidiacea Class Thaliacea Class Appendicularia Class Sorberacea Subphylum Vertebrata Infraphylum incertae sedis Cyclostomata Superclass'Agnatha' paraphyletic Class Myxini Class Petromyzontida or Hyperoartia Class †Conodonta Class †Myllokunmingiida Class †Pteraspidomorphi Class †Thelodonti Class †Anaspida Class †Cephalaspidomorphi Infraphylum Gnathostomata Class †Placodermi Class Chondrichthyes Class †Acanthodii Superclass Osteichthyes Class Actinopterygii Class Sarcopterygii Superclass Tetrapoda Class Amphibia Class Sauropsida Class Synapsida Craniates, one of the three subdivisions of chordates, all have distinct skulls.
They include the hagfish. Michael J. Benton commented that "craniates are characterized by their heads, just as chordates, or all deuterostomes, are by their tails". Most craniates are vertebrates; these consist of a series of bony or cartilaginous cylindrical vertebrae with neural arches that protect the spinal cord, with projections that link the vertebrae. However hagfish have incomplete braincases and no vertebrae, are therefore not regarded as vertebrates, but as members of the craniates, the group from which vertebrates are thought to have evolved; however the cladistic exclusion of hagfish from the vertebrates is controversial, as they ma
