Henry Of Langenstein
Henry of Langenstein, also known as Henry of Hesse the Elder (german: Heinrich von Langenstein; born Heinrich Heinbuche; c. 1325 – 11 February 1397), was a German scholastic philosopher, theologian and mathematician. Biography Henry was born at Hainbuch (Hembuche), near Langenstein, in the Landgraviate of Hesse. He studied at the University of Paris, where he finished his M.A. in 1363 and his M.Th. in 1376, and became professor of philosophy there this same year. In 1368, on the occasion of the appearance of a comet, which the astrologers of his times claimed to be a sure foreboding of certain future events, he wrote a treatise entitled ''Quaestio de cometa'', in which he refutes the then prevalent astrological beliefs. At the instance of the university he wrote three other treatises on the same subject, completed in 1373. On his scientific work, A. C. Crombie writes :''Oresme extended the impetus theory to psychology. One of his followers, Henry, while doubting whet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''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 natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...

Council Of Pisa
The Council of Pisa was a controversial ecumenical council of the Catholic Church held in 1409. It attempted to end the Western Schism by deposing Benedict XIII (Avignon) and Gregory XII (Rome) for schism and manifest heresy. The College of Cardinals, composed of members of both the Avignon Obedience and the Roman Obedience, who were recognized by each other and by the Council, then elected a third papal claimant, Alexander V, who lived only a few months. He was succeeded by John XXIII. Preliminaries During the Conclave of November 1406, Cardinal Angelo Correr had promised, along with all the other cardinals who signed the Electoral Capitulations, that if elected Pope, he would not create new cardinals except to keep the college of the Roman Obedience on a par with the Avignon Obedience. When he was elected Pope Gregory XII, he signed and ratified those capitulations. But in May 1408, without need, he insisted on creating four new cardinals, two of whom were his nephews. Th ...

Pietro Philargi
Peter of Candia, also known as Peter Phillarges (c. 1339 – May 3, 1410), named as Alexander V ( la, Alexander PP. V; it, Alessandro V), was an antipope elected by the Council of Pisa during the Western Schism (1378–1417). He reigned briefly from June 26, 1409 to his death in 1410, in opposition to the Roman pope Gregory XII and the Avignon antipope Benedict XIII. In the 20th century, the Catholic Church reinterpreted the Western Schism by recognizing the Roman popes as legitimate. Gregory XII's reign was extended to 1415, and Alexander V is now regarded as an antipope. Life Alexander V was born near present-day Neapoli in Crete, then part of the Republic of Venice, in 1339. He was baptised Pietro Filargo, but is often known by the names Pietro di Candia and Peter Philarges. He entered the Franciscan order, and his abilities were such that he was sent to study at the universities of Oxford and Paris. While he was in Paris the Western Schism occurred; Philarges supported Pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conrad Of Gelnhausen
Conrad of Gelnhausen ( 1320 – 1390) was a German theologian and canon lawyer, and one of the founders of the conciliar movement of the late fourteenth century. Details of his life are sketchy. He was ''baccalaureus'' at the University of Paris in 1344. For the two decades after then he can be tracked by prebends he is known to have had, in various places in Germany. He turned towards the law later in his career. His influence was through writings from around 1380, after the Western Schism of 1378, the ''Epistola brevis'' and the ''Epistola concordiae''. These appealed for the calling of an autonomous General Council to settle matters. This idea was taken up by others, such as Henry of Langenstein Henry of Langenstein, also known as Henry of Hesse the Elder (german: Heinrich von Langenstein; born Heinrich Heinbuche; c. 1325 – 11 February 1397), was a German scholastic philosopher, theologian and mathematician.

General Council (Christianity)
An ecumenical council, also called general council, is a meeting of bishops and other church authorities to consider and rule on questions of Christian doctrine, administration, discipline, and other matters in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church. The word "ecumenical" derives from the Late Latin ''oecumenicus'' "general, universal", from Greek ''oikoumenikos'' "from the whole world", from ''he oikoumene ge'' "the inhabited world" (as known to the ancient Greeks); the Greeks and their neighbors, considered as developed human society (as opposed to barbarian lands); in later use "the Roman world" and in the Christian sense in ecclesiastical Greek, from ''oikoumenos'', present passive participle of ''oikein'' ("inhabit"), from ''oikos'' ("house, habitation"). The first seven ecumenical councils, recognised by both the eastern and western denominations comprising Chalcedonian Christianity ...

Clement VII
Pope Clement VII ( la, Clemens VII; it, Clemente VII; born Giulio de' Medici; 26 May 1478 – 25 September 1534) was head of the Catholic Church and ruler of the Papal States from 19 November 1523 to his death on 25 September 1534. Deemed "the most unfortunate of the popes", Clement VII's reign was marked by a rapid succession of political, military, and religious struggles—many long in the making—which had far-reaching consequences for Christianity and world politics. Elected in 1523 at the end of the Italian Renaissance, Clement came to the papacy with a high reputation as a statesman. He had served with distinction as chief advisor to Pope Leo X (1513–1521), Pope Adrian VI (1522–1523), and commendably as gran maestro of Florence (1519–1523). Assuming leadership at a time of crisis, with the Protestant Reformation spreading; the Church nearing bankruptcy; and large, foreign armies invading Italy, Clement initially tried to unite Christendom by making peace among the ...

Urban VI
Pope Urban VI ( la, Urbanus VI; it, Urbano VI; c. 1318 – 15 October 1389), born Bartolomeo Prignano (), was head of the Catholic Church from 8 April 1378 to his death in October 1389. He was the most recent pope to be elected from outside the College of Cardinals. His pontificate began shortly after the end of the Avignon Papacy. It was marked by immense conflict between rival factions as part of the Western Schism, with much of Europe recognizing Antipope Clement VII, Clement VII, based in Avignon, as the true pope. Early life Born in Itri, then part of the Kingdom of Naples, Prignano was a devout monk and learned casuist, trained at Avignon. On 21 March 1364 he was consecrated Archbishop of Acerenza in the Kingdom of Naples. He became Archbishop of Bari in 1377. Prignano had developed a reputation for simplicity and frugality and a head for business when acting vice-chancellor. He also demonstrated a penchant for learning, and, according to Cristoforo di Piacenza, he had no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Schism
The Western Schism, also known as the Papal Schism, the Vatican Standoff, the Great Occidental Schism, or the Schism of 1378 (), was a split within the Catholic Church lasting from 1378 to 1417 in which bishops residing in Rome and Avignon both claimed to be the true pope, and were joined by a third line of Pisan claimants in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy. These rival claims to the papal throne damaged the prestige of the office. The papacy had resided in Avignon since 1309, but Pope Gregory XI returned to Rome in 1377. However, the Catholic Church split in 1378 when the College of Cardinals declared it had elected both Urban VI and Clement VII pope within six months of Gregory XI's death. After several attempts at reconciliation, the Council of Pisa (1409) declared that both rivals were illegitimate and declared elected a third purported pope. The schism was f ...

Oresme
Nicole Oresme (; c. 1320–1325 – 11 July 1382), also known as Nicolas Oresme, Nicholas Oresme, or Nicolas d'Oresme, was a French philosopher of the later Middle Ages. He wrote influential works on economics, mathematics, physics, astrology and astronomy, philosophy, and theology; was Bishop of Lisieux, a translator, a counselor of King Charles V of France, and one of the most original thinkers of 14th-century Europe. Life Nicole Oresme was born c. 1320–1325 in the village of Allemagnes (today's Fleury-sur-Orne) in the vicinity of Caen, Normandy, in the diocese of Bayeux. Practically nothing is known concerning his family. The fact that Oresme attended the royally sponsored and subsidised College of Navarre, an institution for students too poor to pay their expenses while studying at the University of Paris, makes it probable that he came from a peasant family. Oresme studied the "arts" in Paris, together with Jean Buridan (the so-called founder of the French school of natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
