Cassini Map
The Cassini Map or Academy's Map is the first topographic and geometric map made of the Kingdom of France as a whole. It was compiled by the Cassini family, mainly César-François Cassini (Cassini III) and his son Jean-Dominique Cassini (Cassini IV) in the 1700s. It was on a scale of one line to 100 toises, i.e. 1/86,400. The map was, for the time, a real innovation and a decisive technical advance. It is the first map to be based on a geodesic triangulation. Four generations of the Cassini carried out the work, taking more than 6 decades to complete. The map does not precisely locate dwellings or the boundaries of swamps and forests, but the level of precision of the road network represented is such that by superimposing satellite photos onto map sheets of France, spectacular results are obtained. The work of the Cassinis even left its mark on the land where today you can still find toponyms such as "''Signal of Cassini."'' Such landmarks correspond to the corners of th ...

Versailles 0 Carte Cassini
The Palace of Versailles ( ; french: Château de Versailles ) is a former royal residence built by King Louis XIV located in Versailles, about west of Paris, France. The palace is owned by the French Republic and since 1995 has been managed, under the direction of the French Ministry of Culture, by the Public Establishment of the Palace, Museum and National Estate of Versailles. Some 15,000,000 people visit the palace, park, or gardens of Versailles every year, making it one of the most popular tourist attractions in the world. Louis XIII built a simple hunting lodge on the site of the Palace of Versailles in 1623 and replaced it with a small château in 1631–34. Louis XIV expanded the château into a palace in several phases from 1661 to 1715. It was a favorite residence for both kings, and in 1682, Louis XIV moved the seat of his court and government to Versailles, making the palace the ''de facto'' capital of France. This state of affairs was continued by Kings Louis XV an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of France
The Kingdom of France ( fro, Reaume de France; frm, Royaulme de France; french: link=yes, Royaume de France) is the historiographical name or umbrella term given to various political entities of France in the medieval and early modern period. It was one of the most powerful states in Europe since the High Middle Ages. It was also an early colonial power, with possessions around the world. France originated as West Francia (''Francia Occidentalis''), the western half of the Carolingian Empire, with the Treaty of Verdun (843). A branch of the Carolingian dynasty continued to rule until 987, when Hugh Capet was elected king and founded the Capetian dynasty. The territory remained known as ''Francia'' and its ruler as ''rex Francorum'' ("king of the Franks") well into the High Middle Ages. The first king calling himself ''rex Francie'' ("King of France") was Philip II, in 1190, and officially from 1204. From then, France was continuously ruled by the Capetians and their cadet lin ...

César-François Cassini De Thury
César-François Cassini de Thury (17 June 1714 – 4 September 1784), also called Cassini III or Cassini de Thury, was a French astronomer and cartographer. Biography Cassini de Thury was born in Thury-sous-Clermont, in the Oise department, the second son of Jacques Cassini and Suzanne Françoise Charpentier de Charmois. He was a grandson of Giovanni Domenico Cassini, and would become the father of Dominique, comte de Cassini, Jean-Dominique Cassini, Comte de Cassini. In 1739, he became a member of the French Academy of Sciences as a supernumerary adjunct astronomer, in 1741 as an adjunct astronomer, and in 1745 as a full member astronomer. In January, 1751 he was elected a Fellow of the Royal Society. He succeeded to his father's official position in 1756 and continued the hereditary surveying operations.Jonathan Powell, ''From Cave Art to Hubble: A History of Astronomical Record Keeping'', (Springer Nature Switzerland AG, 2019), 115 In 1744, he began the construction ...

Dominique, Comte De Cassini
Jean-Dominique, comte de Cassini (30 June 174818 October 1845) was a French astronomer, son of César-François Cassini de Thury and great-grandson of Giovanni Domenico Cassini. Cassini was born at the Paris Observatory. He succeeded his father as director of the observatory in 1784; but his plans for its restoration and re-equipment were wrecked in 1793 by the animosity of the National Assembly. His position having become intolerable, he resigned on 6 September and was thrown into prison in 1794, but released after seven months. He then withdrew to Thury, where he died in 1845. In 1770, he published an account of a voyage to America in 1768, undertaken as the commissary of the French Academy of Sciences with a view to testing Pierre Le Roy’s watches at sea. In 1783, he sent a memoir to the Royal Society in which he proposed a trigonometric survey connecting the observatories of Paris and Greenwich for the purpose of better determining the latitude and longitude of the latt ...

Ligne
The ''ligne'' ( ), or line or Paris line, is a historic unit of length used in France and elsewhere prior to the adoption of the metric system in the late 18th century, and used in various sciences after that time. The ''loi du 19 frimaire an VIII'' (Law of 10 December 1799) states that one metre is equal to exactly 443.296 French lines. It is vestigially retained today by French and Swiss watchmakers to measure the size of watch casings, in button making and in ribbon manufacture. Current use Watchmaking There are 12 ''lignes'' to one French inch (''pouce''). The standardized conversion for a ligne is 2.2558291 mm (1 mm = 0.443296 ''ligne''), and it is abbreviated with the letter L or represented by the triple prime, . One ligne is the equivalent of 0.0888 international inch. This is comparable in size to the British measurement called "line" (one-twelfth of an English inch), used prior to 1824. (The French inch at that time was slightly larger than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toise
A toise (; symbol: T) is a unit of measure for length, area and volume originating in pre-revolutionary France. In North America, it was used in colonial French establishments in early New France, French Louisiana (''Louisiane''), Acadia (''Acadie'') and Quebec. The related () was used in Portugal, Brazil, and other parts of the Portuguese Empire until the adoption of the metric system. Definition Unit of length * 1 toise was divided in 6 feet (french: pieds) or 72 inches () or 864 lines () in France until 1812. : In 1799 the metre was defined to be exactly 443.296 or toise, with the intention that the metre should equal of the distance from the pole to the equator. This had the effect of making the toise approximately 1949.03631 mm. : According to an article written in 1866, during measurement of various standard length artefacts from several countries, the toise was measured as 1,949.03632 mm. :Since before 1394, the standard for the toise of Paris was an iron ...

Geodesic
In geometry, a geodesic () is a curve representing in some sense the shortest path ( arc) between two points in a surface, or more generally in a Riemannian manifold. The term also has meaning in any differentiable manifold with a connection. It is a generalization of the notion of a "straight line". The noun '' geodesic'' and the adjective ''geodetic'' come from ''geodesy'', the science of measuring the size and shape of Earth, though many of the underlying principles can be applied to any ellipsoidal geometry. In the original sense, a geodesic was the shortest route between two points on the Earth's surface. For a spherical Earth, it is a segment of a great circle (see also great-circle distance). The term has since been generalized to more abstract mathematical spaces; for example, in graph theory, one might consider a geodesic between two vertices/nodes of a graph. In a Riemannian manifold or submanifold, geodesics are characterised by the property of having vanishin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliothèque Nationale De France
The Bibliothèque nationale de France (, 'National Library of France'; BnF) is the national library of France, located in Paris on two main sites known respectively as ''Richelieu'' and ''François-Mitterrand''.

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Colbert
Jean-Baptiste Colbert (; 29 August 1619 – 6 September 1683) was a French statesman who served as First Minister of State from 1661 until his death in 1683 under the rule of King Louis XIV. His lasting impact on the organization of the country's politics and markets, known as Colbertism, a doctrine often characterized as a variant of mercantilism, earned him the nickname ''le Grand Colbert'' (; "the Great Colbert"). A native of Reims, he was appointed Intendant of Finances on 4 May 1661. Colbert took over as Controller-General of Finances, a newly elevated position, in the aftermath of the arrest of Nicolas Fouquet for embezzlement, an event that led to the abolishment of the office of Superintendent of Finances. He worked to develop the domestic economy by raising tariffs and encouraging major public works projects, as well as to ensure that the French East India Company had access to foreign markets, so that they could always obtain coffee, cotton, dyewoods, fur, pepper, ...

French Cartography
The history of French cartography can be traced to developments in the Middle Ages. This period was marked by improvements in measuring instruments and also by an upgrade of work in registers of all types. What is thought to be the oldest land map in Europe, the Saint-Bélec slab, representing an area of the Odet valley, was found in 1900, and rediscovered in a castle cellar in France in 2014. The Bronze-Age stone is thought to be 4,000-years old. The first map of France was drawn by Oronce Finé and printed in woodcuts in 1525. It testifies to the will of the political power to mark its presence on the territory; to affirm, to build limits, borders, to arrange its territory, and to consolidate the internal economic markets. In the 16th century, Dieppe appeared as an important school of cartography. Pierre Desceliers allowed the realization of many maps. At the same time, the Portolan maps of the Portuguese sailors had the most recent knowledge obtained by the Dieppois sailors in ...
