Great Basilica, Pliska
The Great Basilica of Pliska ( bg, Голяма базилика в Плиска, translit=Golyama bazilika v Pliska) is an architectural complex in Pliska, the first capital of the First Bulgarian Empire, which includes the cathedral, an archbishop's palace and a monastery. The basilica was constructed on the orders of the ''knyaz'' of Bulgaria, Boris I (), after his baptism in 864 and the resultant Christianization of Bulgaria. Completed around 875, the basilica was long and wide. The complex includes Great Basilica itself – a basilica used as the cathedral church – and the attached monastery and episcopal palace inhabited by Christian monks and the bishop of Pliska. Description The basilica was built at the place of what is known as the cross-shaped Mausoleum, an older religious building that is thought by some researchers to be an unknown kind of Bulgar heathen temple. According to the Shumen architectural museum's research, an early Christian martyrium that included a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliska
Pliska ( , cu, Пльсковъ, translit=Plĭskovŭ) was the first capital of the First Bulgarian Empire during the Middle Ages and is now a small town in Shumen Province, on the Ludogorie plateau of the Danubian Plain, 20 km northeast of the provincial capital, Shumen. Pliska was the first capital of Bulgaria, and according to legend founded by Asparuh of Bulgaria in the late 7th century; this legend is archaeologically unsubstantiated. The site was originally an encampment, with the first tent-shaped buildings at Pliska of uncertain date. No evidence exists of a settlement before the 9th century, and claims that the site dates from Late Antiquity have been contested. By the early 9th century, Pliska was surrounded by a defensive wall and of land was further enclosed by an outer earthwork with stone revetment long. After the Byzantine army sacked and burned Pliska in 811, led by the emperor Nikephoros I (), Pliska was rebuilt by Omurtag (), who used ''spolia'' from ...

Hypocaust
A hypocaust ( la, hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes. This air can warm the upper floors as well. The word derives from the Ancient Greek meaning "under" and , meaning "burnt" (as in ''caustic''). The earliest reference to such a system suggests that the temple of Ephesus in 350 BC was heated in this manner, although Vitruvius attributes its invention to Sergius Orata in c. 80 BC. Its invention improved the hygiene and living conditions of citizens, and was a forerunner of modern central heating. Roman operation Hypocausts were used for heating hot baths and other public buildings in Ancient Rome. They were also used in private homes. It was a must for the villas of the wealthier merchant class throughout the Roman Empire. The ruins of Roman hypocausts have been found throughout Europe (for example in Ital ...

Late Antique
Late antiquity is the time of transition from classical antiquity to the Middle Ages, generally spanning the 3rd–7th century in Europe and adjacent areas bordering the Mediterranean Basin. The popularization of this periodization in English has generally been credited to historian Peter Brown, after the publication of his seminal work '' The World of Late Antiquity'' (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (235–284) to the early Muslim conquests (622–750), or as roughly contemporary with the Sasanian Empire (224–651). In the West its end was earlier, with the start of the Early Middle Ages typically placed in the 6th century, or earlier on the edges of the Western Roman Empire. The Roman Empire underwent considerable social, cultural and organizational changes starting with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spolia
''Spolia'' (Latin: 'spoils') is repurposed building stone for new construction or decorative sculpture reused in new monuments. It is the result of an ancient and widespread practice whereby stone that has been quarried, cut and used in a built structure is carried away to be used elsewhere. The practice is of particular interest to historians, archaeologists and architectural historians since the gravestones, monuments and architectural fragments of antiquity are frequently found embedded in structures built centuries or millennia later. The archaeologist Philip A. Barker gives the example of a late Roman period (probably 1st-century) tombstone from Wroxeter that could be seen to have been cut down and undergone weathering while it was in use as part of an exterior wall and, possibly as late as the 5th century, reinscribed for reuse as a tombstone. Overview The practice was common in late antiquity. Entire obsolete structures, including underground foundations, are known to ...

Omurtag Of Bulgaria
Omurtag (or Omortag) ( bg, Омуртаг; original gr, Μορτάγων and Ομουρτάγ', Inscription No.64. Retrieved 10 April 2012.) was a Great Khan (''Kanasubigi'') of Bulgaria from 814 to 831. He is known as "the Builder". In the very beginning of his reign he signed a 30-year peace treaty with the neighboring Byzantine Empire which remained in force to the end of his life. Omurtag successfully coped with the aggressive policy of the Frankish Empire to take Bulgaria's north-western lands and suppressed the unrest among several Slavic tribes. He made administrative reforms which increased the power and the authority of the central government. His reign was marked with a strong development of Bulgarian architecture with a number of significant construction projects. Rise to the throne After the death of Khan Krum there was a short period of political instability in the country. Some sources mention that Bulgaria was ruled by three nobles - "Dukum" (Δούκουμος; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikephoros I
Nikephoros I or Nicephorus I ( gr, Νικηφόρος; 750 – 26 July 811) was Byzantine emperor from 802 to 811. Having served Empress Irene as '' genikos logothetēs'', he subsequently ousted her from power and took the throne himself. In reference to his career before becoming emperor, he is sometimes surnamed "the Logothete" (ὁ Λογοθέτης) and "Genikos" or "Genicus" (ὁ Γενικός). Nikephoros pursued wars against the Arabs and Bulgarians, with mixed results; while invading Bulgaria he was defeated and killed at the Battle of Pliska. Background Sources outside the Byzantine context, including Michael the Syrian, al-Tabari, and Mas'udi, preserve the tradition that Nikephoros was of Ghassanid Arab origin. al-Tabari claims that he derived this information from Byzantine sources, but no surviving Byzantine chronicle makes explicit mention of the emperor's ethnic background. The modern scholar Paul Julius Alexander suggests that al-Tabari did transmit informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revetment
A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a ... and protect it from erosion. River or coastal revetments are usually built to preserve the existing uses of the shoreline and to protect the slope. In military engineering it is a sloped structure formed to secure an area from artillery, bombing, or stored explosives. Freshwater revetments Many revetments are used to line the banks of freshwater rivers, lakes, and man-made reservoirs, especially to prevent damage during periods of floods or heavy seasonal rains (see riprap).

Defensive Wall
A defensive wall is a fortification usually used to protect a city, town or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications with towers, bastions and gates for access to the city. From ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as ''letzis'' were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls also had important symbolic functions representing the status and independence of the communities they embraced. Existing ancient walls are almost always masonry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asparuh Of Bulgaria
Asparuh (also ''Ispor''; bg, Аспарух, Asparuh or (rarely) bg, Исперих, Isperih) was а ruler of Bulgars in the second half of the 7th century and is credited with the establishment of the First Bulgarian Empire in 681. Early life The '' Nominalia of the Bulgarian khans'' states that Asparuh belonged to the Dulo clan and reigned for 61 years. This long period cannot be accepted as accurate due to chronological constraints, and may indicate the length of Asparuh's life. According to the chronology developed by Moskov, Asparuh would have reigned 668–695. Other chronologies frequently end his reign in 700 or 701 but cannot be reconciled with the testimony of the ''Namelist''. According to the Byzantine sources, Asparuh was a younger son of Kubrat, who had established a spacious state ("Great Bulgaria") in the steppes of modern Ukraine. Asparuh may have gained experience in politics and statesmanship during the long reign of his father, who probably died in 665 ...
