John Of Lignères
John of Lignéres or Johannes de Lineriis () was a French astronomer who wrote several works on the calculation of moon, sun, and planetary positions. Many of his works are confounded with the works of similar named Parisian astronomer collaborators and students including Johns of Murs, John of Sicily, John of Saxony, and John of Montfort. His works were important in importing Arabic astronomical calculations into European traditions. John was from Amiens and lived in Paris from 1320 to 1335. He may have been born in Ligneres, 37 km southeast of Amiens. Little is known of his life other than his writings. He is considered as the key promoter of the Alfonsine tables The ''Alfonsine Tables'' (, ), sometimes spelled ''Alphonsine Tables'', provided data for computing the position of the Sun, Moon and planets relative to the fixed stars. The tables were named after Alfonso X of Castile, who sponsored their cr ... in Europe. His works include tables, canons to the tables and a trea ...

En:John Of Saxony (astronomer)
John of Saxony (also Johannes de Saxonia, John Danko or Dancowe of Saxony) was a medieval astronomer. Although his exact birthplace is unknown it is believed he was born in Germany, most likely Magdeburg. His scholarly work is believed to date from the end of the 13th century into the mid 14th century. He spent most of his active career, from about 1327 to 1355, at the University of Paris. Scholarship John of Saxony is quoted in various medieval manuscripts and referenced as the author of various astronomical or astrological treatises, even though his authorship in some cases is questionable. A ''computus'' dating back to 1297 is attributed to John of Saxony even though the author is listed as Iohannes Alemanus. The fact that the geographical longitudes of Paris and Magdeburg, considered John's birthplace, among other facts is why some historians consider him the author. Viewed with less suspicion is his commentary on ''Liber Introductorius ad Magisterium Idiciorum Astrorum'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Catholic Diocese Of Amiens
The Diocese of Amiens (Latin: ''Dioecesis Ambianensis''; French: ''Diocèse d'Amiens'') is a Latin Church diocese of the Catholic Church in France. The diocese comprises the department of Somme, of which the city of Amiens is the capital. In 2022 it was estimated that there was one priest for every 6,916 Catholics in the diocese. History The diocese of Amiens was a suffragan of the Archdiocese of Reims during the old regime; it was made subordinate to the diocese of Paris under the Concordat of 1801, from 1802 to 1822; and then in 1822 it became a suffragan of Reims again. Louis Duchesne denies any value to the legend of two Saints Firmin, honoured on the first and twenty-fifth of September, as the first and third Bishops of Amiens. The legend is of the 8th century and incoherent. Regardless of whether a St. Firmin, native of Pampeluna, was martyred during the Diocletianic Persecution, it is certain that the first bishop known to history is St. Eulogius, who defended the d ...

Alfonsine Tables
The ''Alfonsine Tables'' (, ), sometimes spelled ''Alphonsine Tables'', provided data for computing the position of the Sun, Moon and planets relative to the fixed stars. The tables were named after Alfonso X of Castile, who sponsored their creation. They were compiled in Toledo, Spain, and contain astronomical data starting on June 1, 1252, the date of the coronation of the King. Production Alfonso X assembled a team of scholars, known as the Toledo School of Translators, who among other translating tasks, were asked to produce new tables that updated the '' Tables of Toledo''. The new tables were based on earlier astronomical works and observations by Islamic astronomers, adding observations by astronomers Alfonso had gathered in Toledo, among them several Jewish scholars, like Yehuda ben Moshe and Isaac ibn Sid. He also brought Aben Raghel y Alquibicio and Aben Musio y Mohamat, from Seville, Joseph Aben Alí and Jacobo Abenvena, from Córdoba, and fifty more from Gas ...
