John Curcuas (catepan)
John Kourkouas or Curcuas ( gr, Ἰωάννης Κουρκούας) was the Byzantine catepan of Italy from 1008–1010. John belonging to the Kourkouas family of Armenian descent. According to a deed of grant to the monastery of San Giovanni in Lamis, he bore the titles of and .. Kourkouas arrived at Bari in May 1008, as a replacement for Alexios Xiphias, who had died sometime between April and August of the previous year. He served as catepan of Italy until some time before March 1010, when his successor, Basil Mesardonites, is attested in office. According to the Italian chronicles of Lupus Protospatharius and Anonymus Barensis, he died in office in 1010. Nothing is known of his tenure, as the only information about him comes from deeds confirmed by his successors, and brief references in Italian sources. John's government coincided with the first revolt of the Lombards in Greek Apulia, under Melus of Bari. A possible descendant or relative, the notary John Kourkouas, is ...

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 Rome ...

Anonymus Barensis
''Anonymi Barensis Chronicon'' is a medieval Italian annalistic chronicle. Composed in Latin by an anonymous author from Bari in the first quarter of the 12th century, it covers the years 855–1118, concentrating first and foremost on the events in Bari and Apulia. The First Crusade is followed in some detail, however, as are the Byzantine affairs. ''Anonymi Barensis Chronicon'' has much content in common with two other Bariot chronicles, ''Annales Barenses'' and, especially, '' Annales Lupi Protospatharii'' (with which it also shares the beginning). Therefore, all three are assumed to be based on some older chronicle that no longer survives. The ''Chronicon'' becomes more detailed from the 1040s on, also diverging in coverage from the other chronicles. No medieval copy of ''Anonymi Barensis Chronicon'' is known. The survival of the chronicle is due to the 17th-century Italian historian Camillo Pellegrino who transcribed the text from a manuscript in Salerno and published it in ...

Byzantine Generals
A Byzantine fault (also Byzantine generals problem, interactive consistency, source congruency, error avalanche, Byzantine agreement problem, and Byzantine failure) is a condition of a computer system, particularly distributed computing systems, where components may fail and there is imperfect information on whether a component has failed. The term takes its name from an allegory, the "Byzantine generals problem", developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system's actors must agree on a concerted strategy, but some of these actors are unreliable. In a Byzantine fault, a component such as a server can inconsistently appear both failed and functioning to failure-detection systems, presenting different symptoms to different observers. It is difficult for the other components to declare it failed and shut it out of the network, because they need to first reach a consensus regarding which component has failed in the first pla ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
