Beda Venerabilis' Easter Cycle
In the year 616 an anonymous scholar extended Dionysius Exiguus' Easter table to an Easter table covering the years 532 up to and including 721. Dionysius' table was published in 525 and only a century later accepted by the church of Rome, which from the third century up till then had given preference to go on using her own, relatively inadequate, Easter tables. From about the middle of the seventh century all controversy between Alexandria and Rome as to the correct date of Easter ceased, as both churches were now using identical tables. In the year 725 Bede (Latin name Beda Venerabilis) published a new extension of Dionysius’ Easter table to a great Easter cycle, which is periodic in its entirety and in which consequently not only the sequence of (Julian calendar) dates of Alexandrian Paschal full moon but also the sequence of (Julian calendar) dates of Alexandrian Easter Sunday is periodic. Bede's Easter cycle contains lunar cycles (of 19 years) as well as solar cycles (of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dionysius Exiguus' Easter Table
Dionysius Exiguus's Easter table was constructed in the year 525 by Dionysius Exiguus for the years 532–626. He obtained it from an Easter table attributed to Patriarch Cyril of Alexandria for the years 437–531. The latter was constructed around the year 440 by means of extrapolation from an Alexandrian Easter table constructed around the year 390 by Patriarch Theophilus of Alexandria. The great historical importance of Dionysius' Easter table is twofold: # From this Easter table Bede's Easter cycle would ultimately be developed by means of which all future Julian calendar dates of Easter Sunday were determined (as in column G of Dionysius' table); # With his Easter table Dionysius introduced in passing the Christian era (see column A of Dionysius' table) which would be developed into a full system for dating historical events by Bede Bede ( ; ang, Bǣda , ; 672/326 May 735), also known as Saint Bede, The Venerable Bede, and Bede the Venerable ( la, Beda Venerabil ...

State Church Of The Roman Empire
Christianity became the official religion of the Roman Empire when Emperor Theodosius I issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy of Nicene Christians in the Great Church as the Roman Empire's state religion. Most historians refer to the Nicene church associated with emperors in a variety of ways: as the catholic church, the orthodox church, the imperial church, the imperial Roman church, or the Byzantine church, although some of those terms are also used for wider communions extending outside the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church, all claim to stand in continuity from the Nicene church to which Theodosius granted recognition. Earlier in the 4th century, following the Diocletianic Persecution of 303–313 and the Donatist controversy that arose in consequence, Constantine the Great had convened councils of bishops to define the orthodoxy of the Christian faith and to expand on earlier Chr ...

Date Of Easter
As a moveable feast, the date of Easter is determined in each year through a calculation known as (). Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon on or after 21 March (a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the tropical year, solar year, while also accounting for the month, date, and weekday of the Julian calendar, Julian or Gregorian calendar. The complexity of the algorithm arises because of the desire to associate the date of Easter with the date of the Jewish feast of Passover which, Christians believe, is when Jesus was crucified. It was originally feasible for the entire Christian Church to receive the date of Easter each year through an annual announcement by the Pope. By the early third century, however, communications in the Roman Empire had deteriorated to the point that the church put great value in a system that woul ...

Bede
Bede ( ; ang, Bǣda , ; 672/326 May 735), also known as Saint Bede, The Venerable Bede, and Bede the Venerable ( la, Beda Venerabilis), was an English monk at the monastery of St Peter and its companion monastery of St Paul in the Kingdom of Northumbria of the Angles (contemporarily Monkwearmouth–Jarrow Abbey in Tyne and Wear, England). Born on lands belonging to the twin monastery of Monkwearmouth–Jarrow in present-day Tyne and Wear, Bede was sent to Monkwearmouth at the age of seven and later joined Abbot Ceolfrith at Jarrow. Both of them survived a plague that struck in 686 and killed a majority of the population there. While Bede spent most of his life in the monastery, he travelled to several abbeys and monasteries across the British Isles, even visiting the archbishop of York and King Ceolwulf of Northumbria. He was an author, teacher ( Alcuin was a student of one of his pupils), and scholar, and his most famous work, '' Ecclesiastical History of the Engli ...

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematics, Greek mathematicians and Ancient Greek astronomy, astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated #Replacement by the Gregorian calendar, a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the Tropical year, solar year. adoption of the Gregorian calendar, Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic Church, Catholic countries and subsequently in Protestantism, Protestant countries of the Western Christianity, West ...

Paschal Full Moon
An ecclesiastical full moon is formally the 14th day of the ecclesiastical lunar month (an ecclesiastical moon) in an ecclesiastical lunar calendar. The ecclesiastical lunar calendar spans the year with lunar months of 30 and 29 days which are intended to approximate the observed phases of the Moon. Since a true synodic month has a length that can vary from about 29.27 to 29.83 days, the moment of astronomical opposition tends to be roughly 14.75 days after the previous conjunction of the Sun and Moon (the new moon). The ecclesiastical full moons of the Gregorian lunar calendar tend to agree with the dates of astronomical opposition, referred to a day beginning at midnight at 0 degrees longitude, to within a day or so. However, the astronomical opposition happens at a single moment for the entire Earth: The hour and day at which the opposition is measured as having taken place will vary with longitude. In the ecclesiastical calendar, the 14th day of the lunar month, reckoned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Easter Sunday
Easter,Traditional names for the feast in English are "Easter Day", as in the '' Book of Common Prayer''; "Easter Sunday", used by James Ussher''The Whole Works of the Most Rev.

Byzantine Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient ...

Annianus Of Alexandria
Annianus of Alexandria ( grc-gre, italic=yes, Annianos) was a monk who flourished in Alexandria during the bishopric of Theophilus of Alexandria around the beginning of the 5thcentury. He criticized the world history of his contemporary monk Panodorus of Alexandria for relying too much on secular sources rather than biblical sources for his dates. As a result, Annianus developed his own chronology which placed Creation on . This created the Alexandrian Era whose first day was the first day of the proleptic Alexandrian civil year in progress, . This year was eleven Paschal cycles of 532 years each before the Alexandrian year beginning , which itself was four 19-year cycles after the epoch of the Diocletian Era on . The former is known as the Era of Grace in the Coptic Church, whereas the latter is known as the Era of Martyrs. He was the first computist to recognize the 532-year cycle of Easters in the Julian calendar. This cycle is often attributed to Victorius of Aquitaine in 45 ...

Chronology
Chronology (from Latin ''chronologia'', from Ancient Greek , ''chrónos'', "time"; and , '' -logia'') is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".Memidex/WordNet, "chronology,memidex.com (accessed September 25, 2010). Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale. Related fields Chronology is the science of locating historical events in time. It relies upon chronometry, which is also known as timekeeping, and historiography, which examines the writing of history and the use of historical methods.
