Bernard Of Verdun
Little is known of the life of Bernard of Verdun, except that he was a Franciscan friar who may have been born in Verdun and lived in the second half of the thirteenth century. His most significant work was the Treatise on the Whole of Astronomy (''Tractatus super totam astrologiam''), in which he defended Ptolemy's theory of epicycles and eccentrics against al-Bitruji's system of homocentric spheres. Contrary to the criticisms of Averroes and al-Bitruji, Bernard maintained that Ptolemy's theory was consistent with Aristotle's physics Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force.

He further pointed out many technical inadequacies of al-Bitruji's model, and considered it to be insufficiently developed to challenge Ptolemy's system.Bernard of Verdun, "The Reality of Epicyc ...

Franciscan
The Franciscans are a group of related organizations in the Catholic Church, founded or inspired by the Italian saint Francis of Assisi. They include three independent Religious institute, religious orders for men (the Order of Friars Minor being the largest contemporary male order), an order for nuns known as the Order of Saint Clare, and the Third Order of Saint Francis, a Third Order of Saint Francis#Third Order Regular, religious and Secular Franciscan Order, secular group open to male and female members. Franciscans adhere to the teachings and spiritual disciplines of the founder and of his main associates and followers, such as Clare of Assisi, Anthony of Padua, and Elizabeth of Hungary. Several smaller Franciscan spirituality in Protestantism, Protestant Franciscan orders have been established since the late 19th century as well, particularly in the Lutheranism, Lutheran and Anglicanism, Anglican traditions.

Friar
A friar is a member of one of the mendicant orders in the Catholic Church. There are also friars outside of the Catholic Church, such as within the Anglican Communion. The term, first used in the 12th or 13th century, distinguishes the mendicants' itinerant apostolic character, exercised broadly under the jurisdiction of a superior general, from the older monastic orders' allegiance to a single monastery formalized by their vow of stability. A friar may be in holy orders or be a non-ordained brother. The most significant orders of friars are the Dominicans, Franciscans, Augustinians, and Carmelites. Definition Friars are different from monks in that they are called to the great evangelical counsels (vows of poverty, chastity, and obedience) in service to society, rather than through cloistered asceticism and devotion. Whereas monks live in a self-sufficient community, friars work among laypeople and are supported by donations or other charitable support. Monks or nuns m ...

Verdun
Verdun ( , ; ; ; official name before 1970: Verdun-sur-Meuse) is a city in the Meuse (department), Meuse departments of France, department in Grand Est, northeastern France. It is an arrondissement of the department. In 843, the Treaty of Verdun, which divided the Carolingian Empire into three kingdoms—considered the foundation of Germany and France—was signed there. An episcopal principality of the Holy Roman Empire since the 10th century, Verdun was subjugated by France in 1552, during the "Voyage to Austrasia". Along with the other free cities of the Empire, Metz and Toul, it formed the province of the Three Bishoprics, which was attached to the Kingdom of France in 1648 by the Treaty of Münster (1648), Treaty of Münster. Verdun is the biggest city in Meuse, although the capital of the department is Bar-le-Duc, which is slightly smaller than Verdun. It is well known for giving Battle of Verdun, its name to the longest battle in modern history in the World War I, Fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptolemy
Claudius Ptolemy (; , ; ; – 160s/170s AD) was a Greco-Roman mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine science, Byzantine, Islamic science, Islamic, and Science in the Renaissance, Western European science. The first was his astronomical treatise now known as the ''Almagest'', originally entitled ' (, ', ). The second is the ''Geography (Ptolemy), Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian physics, Aristotelian natural philosophy of his day. This is sometimes known as the ' (, 'On the Effects') but more commonly known as the ' (from the Koine Greek meaning 'four books'; ). The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deferent And Epicycle
In the Hipparchian, Ptolemaic, and Copernican systems of astronomy, the epicycle (, meaning "circle moving on another circle") was a geometric model used to explain the variations in speed and direction of the apparent motion of the Moon, Sun, and planets. In particular it explained the apparent retrograde motion of the five planets known at the time. Secondarily, it also explained changes in the apparent distances of the planets from the Earth. It was first proposed by Apollonius of Perga at the end of the 3rd century BC. It was developed by Apollonius of Perga and Hipparchus of Rhodes, who used it extensively, during the 2nd century BC, then formalized and extensively used by Ptolemy in his 2nd century AD astronomical treatise the '' Almagest''. Epicyclical motion is used in the Antikythera mechanism, itation requested/sup> an ancient Greek astronomical device, for compensating for the elliptical orbit of the Moon, moving faster at perigee and slower at apogee than cir ...

Al-Bitruji
Nūr al-Dīn ibn Isḥaq al-Biṭrūjī (, died c. 1204), known in the West by the Latinized name of Alpetragius, was an Arab astronomer and qadi in al-Andalus. Al-Biṭrūjī was the first astronomer to present the concentric spheres model as an alternative to the Ptolemaic system, with the planets borne by geocentric spheres. Another original aspect of his system was proposing a physical cause of celestial motions. His alternative system spread through most of Europe during the 13th century. The crater Alpetragius on the Moon is named after him. Life Almost nothing about his life is known, except that his name probably derives from Los Pedroches (al-Biṭrawsh), a region near Cordoba. He was a disciple of Ibn Tufail (Abubacer) and was a contemporary of Averroes. Planetary model Al-Bitruji proposed a theory on planetary motion in which he wished to avoid both epicycles and eccentrics, and to account for the phenomena peculiar to the wandering stars, by compounding rotati ...

Averroes
Ibn Rushd (14 April 112611 December 1198), archaically Latinization of names, Latinized as Averroes, was an Arab Muslim polymath and Faqīh, jurist from Al-Andalus who wrote about many subjects, including philosophy, theology, medicine, astronomy, physics, psychology, mathematics, neurology, Islamic jurisprudence and Islamic law, law, and linguistics. The author of more than 100 books and treatises, his philosophical works include numerous commentaries on Aristotle, for which he was known in the Western world as ''The Commentator'' and ''Father of Rationalism''. Averroes was a strong proponent of Aristotelianism; he attempted to restore what he considered the original teachings of Aristotle and opposed the Neoplatonism, Neoplatonist tendencies of earlier Muslims, Muslim thinkers, such as al-Farabi and Avicenna. He also defended the pursuit of philosophy against criticism by Ash'ari theologians such as Al-Ghazali. Averroes argued that philosophy was permissible in Islam and eve ...

Aristotle's
Aristotle (; 384–322 BC) was an Ancient Greek philosophy, Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum (classical), Lyceum in Athens, he began the wider Aristotelianism, Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira (ancient city), Stagira in northern Greece during the Classical Greece, Classical period. His father, Nicomachus (father of Aristotle), Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato's Platonic Academy, Academy in Athens and remained there until the age of thirty seven (). Shortly after Plato died, Aristotle left Athens and, at the request ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aristotelian Physics
Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work ''Physics'', Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrialincluding all motion (change with respect to place), quantitative change (change with respect to size or number), qualitative change, and substantial change (" coming to be" existence.html" ;"title="oming into existence">oming into existence, 'generation'or "passing away" [no longer existing, 'corruption']). To Aristotle, 'physics' was a broad field including subjects which would now be called the philosophy of mind, sensory experience, memory, anatomy and biology. It constitutes the foundation of the thought underlying many of his works. Key concepts of Aristotelian physics include the structuring of the cosmos into concentric spheres, with the Earth at the centre and celestial spher ...

Medieval French Astronomers
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire—came und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
