Barcelona Astrolabe
The Barcelona astrolabe is the oldest astrolabe with Carolingian characters that has survived in the Christian Occident. The French researcher Marcel Destombes founded the astrolabe, and left it as legacy to the Institute of the Arab World of Paris in 1983. The Academy of Sciences of Barcelona asked the astrolabe in loan to the Musée of l'Institut du Monde Arabe, to make a replica, today this replica is on display at the Academy of Sciences in the Ramblas. Description This astrolabe presents some unusual characteristics. All the engraved characters are in Latin, this fact made the scholars think that the instrument was made in the Christian Europe. The pointers of his "spider" indicate eighteen stars: ten boreal stars and eight austral stars (that is to say, situated beneath of the equator). Eleven of them correspond to the date of 980 AD. Still like this, the names of the stars are not engraved on the brass. The words ROMA and FRANCIA are engraved in Latin characters in one ...

Astrolabe
An astrolabe (; ; ) is an astronomy, astronomical list of astronomical instruments, instrument dating to ancient times. It serves as a star chart and Model#Physical model, physical model of the visible celestial sphere, half-dome of the sky. Its various functions also make it an elaborate inclinometer and an analog computer, analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. It is able to measure the horizontal coordinate system, altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulation, triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe, ...

Caroline Minuscule
Carolingian minuscule or Caroline minuscule is a script which developed as a calligraphic standard in the medieval European period so that the Latin alphabet of Jerome's Vulgate Bible could be easily recognized by the literate class from one region to another. It is thought to have originated before 778 CE at the scriptorium of the Benedictine monks of Corbie Abbey, about north of Paris, and then developed by Alcuin of York for wide use in the Carolingian Renaissance. Alcuin himself still wrote in a script which was a precursor to the Carolingian minuscule, which slowly developed over three centuries. He was most likely responsible for copying and preserving the manuscripts and upkeep of the script. It was used in the Holy Roman Empire between approximately 800 and 1200. Codices, Christian texts, and educational material were written in Carolingian minuscule. After blackletter developed out of it, the Carolingian minuscule became obsolete, until the 14th century Italian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arab World Institute
The Institut du Monde Arabe (, ''Arab World Institute''; abbr. IMA) is an organisation founded in Paris in 1980 by France with 18 Arab countries to research and disseminate information about the Arab world and its cultural and spiritual values. The Institute was established as a result of a perceived lack of representation for the Arab world in France, and seeks to provide a secular location for the promotion of Arab civilization, art, knowledge, and aesthetics. Housed within the institution are a museum, library, auditorium, restaurant, offices and meeting rooms. History The IMA is located in a building known as the ''Institut du Monde Arabe'', the same name as the institute, on Rue des Fossés Saint Bernard in the 5th arrondissement of Paris, France. Originally, the project was conceived in 1973 by President Valéry Giscard d'Estaing. The museum was constructed between 1981 and 1987 under the presidency of French President Francois Mitterrand as part of his urban development ...

Lupitus Of Barcelona
Lupitus of Barcelona, identified with a Christian archdeacon called Sunifred, was an astronomer in late 10th century Barcelona, then part of the '' Marca Hispanica'', the borderland of Christian France fronting Islamic al-Andalus. Lupitus was instrumental in the transfer of Arabic mathematics, including the astrolabe and the Hindu–Arabic numeral system to Christian Europe. Gerbert of Aurillac in a letter of 984 asks Lupitus for a translation of an Arabic astronomical Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos.

Principality Of Catalonia
The Principality of Catalonia (; ; ; ) was a Middle Ages, medieval and early modern state (polity), state in the northeastern Iberian Peninsula. During most of its history it was in dynastic union with the Kingdom of Aragon, constituting together the Crown of Aragon. Between the 13th and the 18th centuries, it was bordered by the Kingdom of Aragon to the west, the Kingdom of Valencia to the south, the Kingdom of France to the north and by the Mediterranean Sea to the east. The term Principality of Catalonia was official until the 1830s, when the Spanish government implemented the centralized provincial division, but remained in popular and informal contexts. Today, the term ''Principat'' (Principality) is used primarily to refer to the Autonomous communities of Spain, autonomous community of Catalonia in Spain, as distinct from the other Catalan Countries, and often including the historical region of Roussillon in Southern France. The first reference to Catalonia and the Catalans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Gerbert Of Aurillac
Pope Sylvester II (; – 12 May 1003), originally known as Gerbert of Aurillac, was a scholar and teacher who served as the bishop of Rome and ruled the Papal States from 999 to his death. He endorsed and promoted study of Moorish and Greco-Roman arithmetic, mathematics and astronomy, reintroducing to Western Christendom the abacus, armillary sphere, and water organ, which had been lost to Latin Europe since the fall of the Western Roman Empire. He is said to be the first in Christian Europe (outside of Al-Andalus) to introduce the decimal numeral system using the Hindu-Arabic numeral system. Early life Gerbert was born about 946, or at any rate between 945 and 950. His exact birthplace is unknown, but it must have been in what was then the Duchy of Aquitaine, part of the Kingdom of France. More precise proposals include the town of Belliac, near the present-day commune of Saint-Simon, Cantal, or Aurillac. Another speculated location is the province of Auvergne. Gerbert's ...

Historical Scientific Instruments
History is the systematic study of the past, focusing primarily on the Human history, human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on Primary source, primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives o ...
