Sangarius Bridge
The Sangarius Bridge or Bridge of Justinian (Turkish language, Turkish: ''Justinianos Köprüsü'' or ''Beşköprü'') is a late Roman bridge over the river Sakarya River, Sakarya ( la, Sangarius, Greek language, Greek Σαγγάριος) in Anatolia, in modern-day Turkey. It was built by the Byzantine Empire, East Roman Emperor Justinian I (527-565 AD) to improve communications between the capital Constantinople and the Praetorian prefecture of the East, eastern provinces of his empire. With a remarkable length of 430 m, the bridge was mentioned by several contemporary writers, and has been associated with a supposed project, first proposed by Pliny the Younger to Emperor Trajan, to construct a navigable canal that would bypass the Bosporus. Location and history The Sangarius Bridge is located in northwestern Anatolia, in the ancient region of Bithynia, ca. 5 km southwest of the town of Adapazarı. Today, the bridge spans the small Çark Deresi stream (called Mel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adapazarı
Adapazarı () is a city in northwestern Turkey and the central district of Sakarya Province. The province itself was originally named Adapazarı as well. Adapazarı is a part of the densely populated region of the country known as the Marmara Region. In 2014, the city had a population of 462,087. History The history of Adapazarı dates back to 378 BC, when it was called Agrilion (Ἀγρίλιον in Greek). Ancient settlers included Phrygians, Bithynians, Cimmerians, Lydians, Greeks, and Persians, but Adapazarı got its identity from the ancient Hellenistic, Romans, and Greek Byzantine rulers. After Alexander the Great's conquests, the Persians were forced out of the region. One of the most important remains of historical significance is the Justinianus Bridge ( tr, Beş Köprü) built by Byzantine Emperor Justinian in 533 AD. Historically, it was situated on the old military road from Constantinople (now Istanbul) to the east, connected in Late Antiquity by the important Sang ...

Bosporus
The Bosporus Strait (; grc, Βόσπορος ; tr, İstanbul Boğazı 'Istanbul strait', colloquially ''Boğaz'') or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul in northwestern Turkey. It forms part of the continental boundary between Asia and Europe, and divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation. Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks. The Bosporus Strait and the Dardanelles Strait at the opposite end of the Sea of Marmara are together known as the Turkish Straits. Sections of the shore of the Bosporus in Istanbul have been reinforced with concrete or rubble and those sections of the Strait prone to deposition are periodically dredged. Name The name of th ...

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PLRE
''Prosopography of the Later Roman Empire'' (abbreviated as ''PLRE'') is a work of Roman prosopography published in a set of three volumes collectively describing many of the people attested to have lived in the Roman Empire from AD 260, the date of the beginning of Gallienus' sole rule, to 641, the date of the death of Heraclius. Sources cited include histories, literary texts, inscriptions, and miscellaneous written sources. Individuals who are known only from dubious sources (e.g., the ''Historia Augusta''), as well as identifiable people whose names have been lost, are included with signs indicating the reliability. A project of the British Academy, the work set out with the goal of doing The volumes were published by Cambridge University Press, and involved many authors and contributors. Arnold Hugh Martin Jones, John Robert Martindale, and John Morris were the principal editors. *Volume 1, published on March 2, 1971, comes to 1,176 pages and covers the years from 260 to 3 ...

Etos Kosmou
The Byzantine calendar, also called the Roman calendar, the Creation Era of Constantinople or the Era of the World ( grc, Ἔτη Γενέσεως Κόσμου κατὰ Ῥωμαίους, also or , abbreviated as ε.Κ.; literal translation of Ancient Greek Roman year since the creation of the universe), was the calendar used by the Eastern Orthodox Church from c. 691 to 1728 in the Ecumenical Patriarchate.

Theophanes The Confessor
Theophanes the Confessor ( el, Θεοφάνης Ὁμολογητής; c. 758/760 – 12 March 817/818) was a member of the Byzantine aristocracy who became a monk and chronicler. He served in the court of Emperor Leo IV the Khazar before taking up the religious life. Theophanes attended the Second Council of Nicaea in 787 and resisted the iconoclasm of Leo V the Armenian, for which he was imprisoned. He died shortly after his release. Theophanes the Confessor, venerated on 12 March in both the Eastern Orthodox and the Roman Catholic churches, should not be confused with Theophanes of Nicaea, whose feast is commemorated on 11 October. Biography Theophanes was born in Constantinople of wealthy and noble iconodule parents: Isaac, governor of the islands of the Aegean Sea, and Theodora, of whose family nothing is known. His father died when Theophanes was three years old, and the Byzantine Emperor Constantine V (740–775) subsequently saw to the boy's education and upbringing at t ...

Agathias
Agathias or Agathias Scholasticus ( grc-gre, Ἀγαθίας σχολαστικός; Martindale, Jones & Morris (1992), pp. 23–25582/594), of Myrina (Mysia), an Aeolian city in western Asia Minor (Turkey), was a Greek poet and the principal historian of part of the reign of the Roman emperor Justinian I between 552 and 558. Biography Agathias was a native of Myrina (Mysia). His father was Memnonius. His mother was presumably Pericleia. A brother of Agathias is mentioned in primary sources, but his name has not survived. Their probable sister Eugenia is known by name. The ''Suda'' clarifies that Agathias was active in the reign of the Roman emperor Justinian I, mentioning him as a contemporary of Paul the Silentiary, Macedonius of Thessalonica and Tribonian. Agathias mentions being present in Alexandria as a law student at the time when an earthquake destroyed Berytus (Beirut). The law school of Berytus had been recognized as one of the three official law schools of the empire ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul The Silentiary
Paul the Silentiary, also known as Paulus Silentiarius ( el, , died AD 575–580), was a Greek Byzantine poet and courtier to the emperor Justinian at Constantinople. Life What little we know of Paul's life comes largely from the contemporary historian and poet Agathias, a friend and admirer, who describes him as coming from a rich and illustrious family, with a father, Cyrus, and a grandfather, Florus, who both probably held public office. Paul also entered public life and became a ''silentiary'' – one of a group of 30 court officials of privileged backgrounds organised under three officers (''decurions'') whose first duty was maintaining order and silence in the Great Palace of Constantinople. They also fulfilled important commissions, especially in church matters, and by the sixth century their order had attained the social rank of ''illustris'', the highest in the late empire. Paul himself may have risen to become their chief (''primicerius''). He died some time between 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procopius
Procopius of Caesarea ( grc-gre, Προκόπιος ὁ Καισαρεύς ''Prokópios ho Kaisareús''; la, Procopius Caesariensis; – after 565) was a prominent late antique Greek scholar from Caesarea Maritima. Accompanying the Roman general Belisarius in Emperor Justinian's wars, Procopius became the principal Roman historian of the 6th century, writing the ''History of the Wars'', the ''Buildings'', and the ''Secret History''. Life Apart from his own writings the main source for Procopius's life was an entry in the ''Suda'',Suda pi.2479. See under 'Procopius' oSuda On Line a Byzantine Greek encyclopaedia written sometime after 975 which discusses his early life. He was a native of Caesarea in the province of ''Palaestina Prima''. He would have received a conventional upper class education in the Greek classics and rhetoric, perhaps at the famous school at Gaza. He may have attended law school, possibly at Berytus (present-day Beirut) or Constantinople (now Istanbul), a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
