85-637: The Daysan River or Daisan River was the name of the river that flowed through Urfa , a tributary of the Khabur . Historically known as the Scirtus ( Ancient Greek : Σκίρτος ), Procopius describes it as a river of Mesopotamia, a western tributary of the Chaboras (modern Khabur). It flowed from 25 sources, and ran past Edessa . ( Chron. Edess. in Asseman, Bibl. Or. i. p. 388.) Its name, which signifies
170-476: A Roman client kingdom. Ma'nu VIII died in 177 and was succeeded by Abgar VIII , also called Abgar the Great. Abgar was stripped of most of his domains except for Edessa, and Osrhoene became a Roman province, when his ally Pescennius Niger lost the civil war to Septimius Severus . Abgar devoted his remaining time to fostering arts and learning. In 201, much of Edessa was destroyed by a major flood. According to

The city is located 30 miles from the Atatürk Dam , at the heart of the Southeast Anatolia Project , which draws thousands of job-seeking rural villagers to the city every year. The oldest name for the city is the Syriac Orhay , which is derived from either the Semitic root -r-w-ʿ , meaning "to bring water", or
340-421: A fire starter. The exact mode of formation of flint is not yet clear, but it is thought that it occurs as a result of chemical changes in compressed sedimentary rock formations during the process of diagenesis . One hypothesis is that a gelatinous material fills cavities in the sediment, such as holes bored by crustaceans or molluscs and that this becomes silicified . This hypothesis would certainly explain
425-453: A letter he wrote to his followers in Edessa. Manichaeism's spread to Edessa was attributed to two of Mani's disciples named Addai and Thomas. Edessa's Manichaean community remained prominent until the 5th century. Abgar the Great died in 212 and was succeeded by Abgar IX , also called Severus as a sign of Roman influence. Abgar IX only reigned for a year – in 213, he was summoned to Rome by
510-408: A majority of its population. The city's culture remained predominantly Semitic (specifically Aramaic), and any Hellenization was minimal. Edessa was an important commercial center in the 3rd and 2nd centuries BC. Previously, the main east-west trade route across Upper Mesopotamia had gone through Harran , but the founding of Edessa caused that route to shift northwards. In 132 BC, following
595-536: A military base in the Mesopotamian limes , although it was secondary to Nisibis in that system. In the 4th through 6th centuries AD, Edessa went through arguably its period of greatest prosperity. It was again an important commercial center, and merchants grew rich on trade in luxury goods from the east, particularly silk. As with later periods, the city had a council of notable citizens who were at least partly in charge of local government and administration. In
680-491: A presence in Edessa, the pagan planet-worshippers increasingly emigrated to Harran. By the early 6th century, a small lake had formed on the west side of the city. In 525, a flood destroyed part of the western city wall and damaged some of the city. Afterwards, a deep ditch was dug on the north and east sides of the city to act as a flood channel . In normal weather, a low dam kept the Daisan river in its original course, but if
765-533: A trigger, strikes a hinged piece of steel (" frizzen ") at an angle, creating a shower of sparks and exposing a charge of priming powder. The sparks ignite the priming powder and that flame, in turn, ignites the main charge, propelling the ball, bullet, or shot through the barrel. While the military use of the flintlock declined after the adoption of the percussion cap from the 1840s onward, flintlock rifles and shotguns remain in use amongst recreational shooters. Flint and steel used to strike sparks were superseded in
850-461: Is a city in southeastern Turkey and the capital of Şanlıurfa Province . The city was known as Edessa from Hellenistic times and into Christian times. Urfa is situated on a plain about 80 km east of the Euphrates . Its climate features extremely hot, dry summers and cool, moist winters. About 12 km (7 mi) northeast of the city is the famous Neolithic site of Göbekli Tepe ,
935-412: Is commonly included in survival kits . Ferrocerium is used in many cigarette lighters, where it is referred to as "a flint". Flint's utility as a fire starter is hampered by its property of uneven expansion under heating, causing it to fracture, sometimes violently, during heating. This tendency is enhanced by the impurities found in most samples of flint that may expand to a greater or lesser degree than

#17327726085681020-577: Is one of the primary materials used to define the Stone Age . During the Stone Age, access to flint was so important for survival that people would travel or trade long distances to obtain the stone. Grime's Graves was an important source of flint traded across Europe. Flint Ridge in Ohio was another important source of flint, and Native Americans extracted the flint from hundreds of quarries along
1105-529: Is the southernmost tower of the Bey Kapısı, on the east side of the city walls. This was completing the rebuilding that Toros had begun before the crusaders seized Edessa and was finished in 1122-3, while the count Joscelin I was in captivity at Harput . The County of Edessa had survived largely because their Muslim rivals were disunited. The rise of a single powerful Muslim rival – namely Imad ad-Din Zangi ,

With permission from the caliph al-Muttaqi , the people of Edessa handed over the mandylion and signed a truce with the Byzantines. The mandylion was translated to Constantinople; it arrived "triumphantly" on 15 August 944. The Numayrid emir Waththab ibn Sabiq declared independence in 990 and annexed Edessa early in his reign. Waththab appointed his cousin 'Utayr as governor of

In October 1031, the Byzantine general George Maniakes conquered Edessa. This would ultimately be the last significant territorial acquisition by the Byzantine Empire in Mesopotamia. The accounts of this event differ heavily. According to one version, Ibn 'Utayr had entered into negotiations with Maniakes, intending to sell him
1360-511: The Chronicle of Edessa , over 2,000 people died. Abgar granted a remission of taxes for people affected by the flood and immediately began a large-scale reconstruction project of the city after the old Seleucid plan. Abgar repaired the old royal palace by the river, which had been damaged by the flood, but he also built a new palace on higher ground. Ancient Edessa was an eclectic melting pot of different religious groups. Unlike Harran, where

In 1938, a project of the Ohio Historical Society , under the leadership of H. Holmes Ellis began to study the knapping methods and techniques of Native Americans . Like past studies, this work involved experimenting with actual knapping techniques by creation of stone tools through
1530-600: The 11th century, there was a large influx of Armenian immigrants into the region, especially the towns. In Urfa, they supplanted Syrians as the leading citizens and wealthiest landowners. Urfa was capital of the crusader County of Edessa for about half a century beginning in 1098. The crusaders' subjects were a mix of Armenians and Syrians. In Urfa itself, Armenians were the dominant group. The crusaders themselves don't seem to have undertaken much construction in Urfa. The only extant structure that can be attributed to them
1615-542: The 1950s when the village was being evacuated to build a base for the Urfa Brigade. The pedestal contains an inscription with an invocation to the god Tarhunza and mentions a city whose name is only partly visible, but which Bahattin Çelik restores as "Umalia", in the country of Bit Adini . Urfa was founded as a city under the name Edessa by the Seleucid king Seleucus I Nicator in 302 or 303 BC. Seleucus named
1700-436: The 20th century by ferrocerium (sometimes referred to as "flint", although not true flint, " mischmetal ", "hot spark", "metal match", or "fire steel"). This human-made material, when scraped with any hard, sharp edge, produces sparks that are much hotter than obtained with natural flint and steel, allowing use of a wider range of tinders. Because it can produce sparks when wet and can start fires when used correctly, ferrocerium
1785-796: The 5th century there were three different theological schools in Edessa: the School of the Syrians (affiliated with the patriarchate of Antioch), the School of the Armenians, and the famous School of the Persians (whose teachers were not actually Persians but rather members of the Church of the East ). The School of the Persians was closed down in 489 and its staff relocated to Nisibis. There were many churches in

#17327726085681870-475: The Byzantine emperor Heraclius captured Edessa. Urfa surrendered to the Rashidun general Iyad ibn Ghanm in 639 without resistance, supposedly when Iyad "stood at its gate riding a brown horse" according to al-Baladhuri . Several versions of the terms of surrender appear in historical sources, mentioning the citizens would be responsible for "repairing 'bridges and roads'". The pact also guaranteed that
1955-484: The Early Bronze Age (2900-2600 BCE) Urfa had grown into a walled city of 200ha. This city is located at the archeological site Kazane Tepe adjacent to modern Urfa. There is a tentative, yet unproven identification of ancient Urfa (Kazane Tepe) with the city of Urshu. A much later artifact is a black stone pedestal with a double bull relief, found at a hill called Külaflı Tepe in the former village of Cavşak in
2040-541: The Greek name "Orrha", meaning "beautiful flowing water". James Silk Buckingham claimed that in earlier times, the city was known as Ruha , and with the Arabic article, it became Ar-Ruha , evolving into Urha , and eventually Urfa . Carsten Niebuhr observed that Turks called the city El-Rohha in the 18th century, although Buckingham who later visited Urfa, disagreed and noted that all Turks, and most Arabs and Kurds in
2125-488: The Neolithic period. In Urfa itself, there was a prehistoric settlement at Yeni Mahalle Höyüğü (aka Balıklıgöl Höyüğü), located immediately north of Balıklıgöl in the heart of the old town. Now buried under single-story houses, the site was accidentally discovered during road construction in the 1990s and then excavated in 1997 by the Şanlıurfa Museum Directorate. The findings included flint tools, arrowheads dated to
2210-656: The Romans captured and destroyed Edessa, and Abgar VII was killed. The Romans installed a Parthian prince, Parthamaspates , on the Edessan throne as a puppet ruler in 117, but the Abgarids were later restored to power. Similarly, the Parthians captured Edessa in 163 and installed Wa'el bar Sharu as a puppet king. The deposed Ma'nu VIII went to the Romans, who took Edessa in 165 and restored Ma'nu to power. In 166, Osrhoene became
2295-548: The Ruṣāfāyē. During the reign of the Abbasid caliph al-Mansur , the city walls were demolished after the local Muslim governor revolted. The old walls had already been damaged by floods in the 7th and 8th centuries. In 812, Urfa's citizens had to pay a large sum to the anti-Abbasid rebel Nasr ibn Shabath al-Uqayli to prevent him from attacking the unprotected city. Afterwards, the citizens had new defensive walls built around
2380-466: The Seljuk citadel commander refused. Tutush's forces seized the citadel and made their encampment on the west side of the city. Fearing an attack from them, Toros apparently tried to cut the citadel off by building a wall between it and the city. After Tutush died in 1095, however, his forces abandoned the citadel and Toros now took control of the whole city as a de facto independent ruler. During
2465-540: The Seljuks, but the Byzantine emperor Romanos Diogenes was deposed and in the political chaos its katepano Paulus ended up siding with the new emperor. In 1077 or 1078, Basil Apokapes besieged and captured Edessa, displacing the Byzantine governor Leo Diabatenos. He was an agent of Philaretos Brachamios , the main Byzantine agent in the region who governed from Marash; however, Basil ruled Edessa independently. In 1081-2, an amir named Khusraw unsuccessfully besieged
2550-498: The Syriac Chronicle of 1234 , this happened in 1087, while Matthew of Edessa wrote that it happened after Buzan's death in 1094. Toros appears to have begun a rebuilding project on the Bey Kapısı fortress, but it wasn't finished until after his rule. Meanwhile, Malik Shah had died in 1092 and a Seljuk dynastic crisis had broken out. In 1094, Malik Shah's brother Tutush demanded the city's surrender, but both Toros and

As a result of Diocletian 's reorganization of the empire in 293, a state-run factory was built at Edessa to make weapons and equipment for the soldiers stationed along the border. In 298, after Galerius Maximianus 's victory over the Sasanians, Edessa was made capital of the new province of Osrhoene. It served as

2805-520: The chalky-soil country of France, the British filled sandbags with flint and used these sandbags as breastworks. Flint pebbles are used as the media in ball mills to grind glazes and other raw materials for the ceramics industry. The pebbles are hand-selected based on colour; those having a tint of red, indicating high iron content, are discarded. The remaining blue-grey stones have a low content of chromophoric oxides and so are less deleterious to
2890-580: The citadel fell two days later on the 26th. Zengi's forces spared the native Christian population and their churches, but the Franks were killed and their churches destroyed. Zengi then appointed Zayn ad-Din Ali Küçük , the commander of his guard, as governor of the city. The fall of Edessa was a direct motivator for the Second Crusade . Christian pilgrims returning to Europe brought news of
2975-449: The citadel. His desire to sell was apparently motivated by a threat from Shibl ad-Dawla. In John Skylitzes 's version, however, Maniakes had bribed Salman, a deputy of Nasr ad-Dawla's, into surrendering the city to him in the middle of the night. If this was the case, then Salman either had some authority over Ibn 'Utayr or had otherwise deposed him. Whoever Maniakes had been negotiating with, Byzantine forces gained control of some of
3060-409: The city Edessa after the ancient capital of Macedonia . Ancient sources describe Seleucid Edessa as following the typical plan for Hellenistic military colonies: its streets were laid out in a grid pattern, with four main streets that intersected each other. There were four city gates, and the main citadel was outside the walls. Macedonian soldiers were settled in the new city, but they never formed
3145-547: The city and monasteries in the area. Just outside the walls were several infirmaries and hospitals. When the Roman emperor Jovian surrendered Nisibis to the Sasanians in 363, an influx of refugees came to Edessa, including many Christians. One of these refugees was the writer and theologian Ephrem the Syrian , who was a co-founder of the School of the Persians in Edessa. According to T.A. Sinclair, as Christianity gained more of
3230-518: The city was attacked by the Turkish leader Khurasan-Salar. For 50 days beginning on 10 March 1071, Urfa was besieged by the Seljuk sultan Alp Arslan . Alp Arslan eventually lifted the siege in return for a large payment and possibly also the submission of its ruler, the doux Basilios Alousianos (son of Alusian of Bulgaria ). After the Battle of Manzikert , Edessa was intended to be handed over to
3315-501: The city's Christians would keep ownership of the cathedral. Sometime shortly after Urfa submitted to Muslim rule, a mosque was built in the city, although its location is unknown. In the early centuries of Arab rule, and particularly under the Umayyads, Urfa was still a major Christian city. It formed part of the province of Diyar Mudar . The city reportedly had 300 or 360 churches, and there were many monasteries. The population
3400-480: The city's conquest, and emissaries from the crusader states also came to appeal for help. The pope responded by issuing the papal bull Quantum praedecessores on 1 December 1145, which directly called for another crusade. Meanwhile, in the Muslim world, news of this victory made Zengi a hero. The caliph gave him many gifts and titles, including al-malik al-mansūr – "the victorious king". In May 1146, there
3485-672: The city. 'Utayr installed someone named Ahmad ibn Muhammad as his na'ib (deputy) here, but then later had him assassinated. This evidently made 'Utayr unpopular with the locals, since Ahmad had treated them well. In 1025/6 (416 AH), the city's inhabitants rebelled and appealed to Nasr ad-Dawla , the Marwanid emir of Diyar Bakr. At first, Nasr ad-Dawla appointed someone named Zangi to be his deputy in Edessa, but Zangi died in 1027. Meanwhile, 'Utayr had been assassinated. This time, Nasr ad-Dawla ended up appointing two deputies to jointly control Edessa: he chose 'Utayr's son, known only by

3570-530: The city. According to Bar Hebraeus , the walls were commissioned by someone named Abu Shaykh and paid for by the citizens. The walls and towers visible today belong to this rebuilding effort, albeit with later renovations. The citadel was likely begun at the same time, probably with the addition of a moat on the south side. When the caliph al-Ma'mun came to power in 813, he dispatched his general Tahir ibn Husayn to Urfa to put down Nasr ibn Shabath's rebellion. The rebels besieged Tahir's forces in Urfa, but
3655-473: The city. After Basil's death in 1083, the citizens of Edessa elected an Armenian named Smbat to succeed him. Smbat was in charge for six months before Philaretos came in person on 23 September 1083. He appointed a Greek eunuch as governor and gave him the title parakoimomenos ; this eunuch was later assassinated by an official named Barsauma. However, Edessa was in a particularly vulnerable position "caught between two blocks of Uqaylid territory", and it

Moreover, the city's population was massacred – the men were put to death, while the women and children were sold into slavery. The city's Christian community, one of the oldest in the world, had been destroyed and never recovered. Although Nur ad-Din

This heating process both removed organic impurities and induced certain physical reactions, including converting some of the quartz to cristobalite . After calcination the flint pebbles were crushed and milled to a fine particle size. However, the use of flint has now been superseded by quartz . Because of

In clay bodies , calcined flint attenuates the shrinkage whilst drying, and modifies the fired thermal expansion. Flint can also be used in glazes as a network former. In preparation for use flint pebbles, frequently sourced from

Certain types of flint, such as that from the south coast of England and its counterpart on the French side of the Channel , contain trapped fossilised marine flora. Pieces of coral and vegetation have been found preserved inside the flint similar to insects and plant parts within amber . Thin slices of

Edessa's Jewish community was probably partly responsible for the rapid spread of Christianity in the city. Abgar the Great reportedly converted to Christianity around the turn of the 3rd century, which if true would make Edessa the first Christian polity in the world. More religions joined
4165-447: The crafty atabeg of Mosul – spelled disaster for the county. The tipping point came in late 1144, when Joscelin II left Edessa with a big chunk of his soldiers to assist Zengi's rival Kara Arslan . Upon becoming aware of the city's weakness, Zengi led a series of forced marches and laid siege to the city on 24 November. By 24 December, he had successfully gained entry to the city;
4250-649: The cult of the moon god Sin predominated, the people of Edessa worshipped a whole pantheon of gods that can generally be identified with planets. In addition to polytheists, Edessa also had a prominent Jewish community. Many of Edessa's Jews were merchants, involved in long-distance trade between the Persian Gulf and the Mediterranean. By the end of the 2nd century, a small Christian community had appeared in Edessa. Christianity also resonated with several religious themes already present in Edessa – besides
4335-470: The dam overflowed, then the floodwaters would flow through the artificial channel instead of into the city. At some point later on, the flood channel became the normal course of the river. Edessa successfully held out during a siege in 544. In 609, however, the Sasanian emperor Khosrow II captured Edessa during his campaign in Mesopotamia. Many of the city's Monophysites were deported to Iran. In 628,

#17327726085684420-710: The decline of the Seleucids, Edessa became the capital of the kingdom of Osrhoene , which was ruled by the Abgarids , an Arabized tribal dynasty with origins in Nisibis . The Abgarids were generally allied with the Parthian Empire and were under Parthian cultural influence as well. In the early second century AD, Abgar VII supported the Roman emperor Trajan 's campaign in Mesopotamia and received him "sumptously" at his court, but later rebelled. In retaliation,
4505-589: The destruction of several churches, claiming that they had illegally been built after the Muslim conquest. That same year, he also had a new mosque built in the tetrapylon in front of the city's Melkite cathedral. Before its conversion into a mosque, the tetrapylon had been a meeting place for church leaders. The locations of the mosque and cathedral are unknown. In the spring of 943, the Byzantine army campaigned in upper Mesopotamia, capturing several cities and either threatening Urfa or, according to Symeon Magister , besieging it outright. The Byzantines demanded that

A son of Abgar IX, known as Ma'nu IX, appears to have been nominally a king until 240; he received an embassy from India in 218, during the reign of Elagabalus , but he did nothing else of note. The monarchy seems to have been restored to power at some point – and Abgar IX
4760-465: The emperor", Niccolò Zorzi remarks that this "does not necessarily imply that Edessa 'enjoyed a certain amount of independence from Byzantium'". The citadel became known as "Maniakes's citadel" at some point. In May 1036, the Numayri prince Ibn Waththab plundered the city and took the patricius of Edessa as prisoner, but the fortress remained in the hands of the Byzantine garrison. A peace treaty

During their six-day-long reoccupation of Urfa, the Franks indiscriminately looted shops belonging to Christians and Muslims alike. The city's Muslims either fled to Harran or took shelter in the citadel with the Turkish garrison. Meanwhile, Imad ad-Din's successor Nur ad-Din Zengi had arrived with an army of 10,000 soldiers and surrounded

A later, major use of flint and steel was in the flintlock mechanism , used primarily in flintlock firearms, but also used on dedicated fire-starting tools. A piece of flint held in the jaws of a spring-loaded hammer, when released by

Exactly which parts Maniakes had taken control of are unclear – Skylitzes described Maniakes had taken possession of "three heavily fortified towers", but his description of Edessa's geography is completely inaccurate and he clearly had never been to the city himself. Matthew of Edessa 's account, which is more reliable, mentions "three citadels"; according to Tara Andrews,
5100-445: The large stronghold of Framlingham Castle . Many different decorative effects have been achieved by using different types of knapping or arrangement and combinations with stone ( flushwork ), especially in the 15th and early 16th centuries. Because knapping flints to a relatively flush surface and size is a highly skilled process with a high level of wastage, flint finishes typically indicate high status buildings. During World War I, in

Flint breaks and chips into sharp-edged pieces, making it useful in constructing a variety of cutting tools, such as knife blades and scrapers. The use of flint to make stone tools dates back more than three million years; flint's extreme durability has made it possible to accurately date its use over this time. Flint

Flint, knapped or unknapped, has been used from antiquity (for example at the Late Roman fort of Burgh Castle in Norfolk) up to the present day as a material for building stone walls, using lime mortar, and often combined with other available stone or brick rubble. It
6035-481: The upper citadel must have been one of them. According to T.A. Sinclair, Maniakes had already gained control of the upper citadel. That winter, Nasr ad-Dawla came with an army in an attempt to drive out the Byzantines. Nasr ad-Dawla tried to besiege the Byzantine positions but was unsuccessful and decided to loot the city and tear down buildings, then burn the city to the ground while retreating with camels carrying off precious objects. According to Skylitzes, Maniakes
6120-487: The use of techniques like direct freehand percussion, freehand pressure and pressure using a rest. Other scholars who have conducted similar experiments and studies include William Henry Holmes , Alonzo W. Pond , Francis H. S. Knowles and Don Crabtree . To reduce susceptibility to fragmentation, flint/chert may be heat-treated, being slowly brought up to a temperature of 150 to 260 °C (300 to 500 °F) for 24 hours, then slowly cooled to room temperature. This makes
6205-405: The variety of chert that occurs in chalk or marly limestone . Historically, flint was widely used to make stone tools and start fires . Flint occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones . Inside the nodule, flint is usually dark grey or black, green, white, or brown in colour, and has a glassy or waxy appearance. A thin, oxidised layer on
6290-429: The world's oldest known temple, which was founded in the 10th millennium BC. The area was part of a network of the first human settlements where the agricultural revolution took place. Because of its association with Jewish , Christian , and Islamic history , and a legend according to which it was the hometown of Abraham , Urfa is nicknamed the "City of Prophets." Religion is important in Urfa. The city "has become
6375-559: Was a plot by Urfa's Armenian community to overthrow the Turks and restore the city to Joscelin II. The Turks suppressed this plot and settled 300 Jewish families in the city. However, after Zengi was assassinated on 14 September 1146, the Armenians again conspired with Joscelin II to take the city. Sometime in October, Joscelin II and Baldwin of Marash came and laid siege to the city. This second siege proved far more destructive than
6460-482: Was a smaller settlement present prior to 303 BC. Perhaps Orhai's absence from earlier written sources is due to the settlement having been small and unfortified prior to the Seleucid period. In prehistoric times, the Urfa Region was attractive for human habitation because of its dense grazing areas and the presence of wild animals on migration routes. As a result, the area became densely populated, particularly in
6545-431: Was able to then capture the citadel and, summoning external reinforcements, secure the whole city. Maniakes remained in charge of Edessa for several years and, according to Honigmann and Bosworth, appears to have been relatively autonomous from the Byzantines, merely sending an annual tribute to Constantinople. On the other hand, while Skylitzes does mention that "Maniakes sent an annual tribute of 50 pounds [of gold] to
6630-461: Was an active builder elsewhere, only one building at Urfa can be attributed to him: the "rather plain" Great Mosque, which was probably on the site of an earlier church. After Nur ad-Din's death in 1174, Urfa was captured by his nephew Sayf al-Din Ghazi II . Flint Flint , occasionally flintstone , is a sedimentary cryptocrystalline form of the mineral quartz , categorized as
6715-576: Was apparently king until 248, when the emperor Philip the Arab had him banished after Edessa rebelled. In 260, the Sasanian emperor Shapur I defeated the Romans in the Battle of Edessa and captured the emperor. However, either Shapur never actually captured the city or he only held it for a very short time – it is not listed among the cities he captured in his inscription on the Ka'ba-ye Zartosht , and in
6800-440: Was deposited at the bottom of inland Paleozoic seas hundreds of millions of years ago that hardened into limestone and later became infused with silica . The flint from Flint Ridge is found in many hues like red, green, pink, blue, white, and grey, with the colour variations caused by minute impurities of iron compounds. Flint can be coloured: sandy brown, medium to dark grey, black, reddish brown or an off-white grey. Flint
6885-423: Was most common in those parts of southern England where no good building stone was available locally, and where brick-making was not widespread until the later Middle Ages. It is especially associated with East Anglia , but also used in chalky areas stretching through Hampshire , Sussex, Surrey and Kent to Somerset . Flint was used in the construction of many churches, houses, and other buildings, for example,
6970-511: Was mostly Syrian Orthodox but with significant Melkite and Jewish minorities; there were relatively few Muslims. The city was led by a group of distinguished citizens, including magnates and agricultural landowners, who "formed a partly self-governing body" that dealt with the caliphal government rather than the bishop. Some of the leading families in this period included the Gūmāyē, the Telmaḥrāyē, and
7055-531: Was particularly vulnerable to the Seljuks. In 1086-7, the Seljuk sultan Malik Shah I sent his general Buzan to take the city while he himself campaigned in Syria. A three-month siege followed, with Barsauma defending the city. The city surrendered in March 1087 and Buzan appointed a Seljuk commander to head the citadel. At some point, an Armenian named Toros in charge of the city administration – according to
7140-498: Was reached in 1037; under its terms, Edessa came directly under Byzantine control and it was refortified. Edessa now became an important Byzantine command placed under a series of katepanos and dukes. The "duchy" of Edessa probably comprised the whole area beyond the Euphrates under their control with several fortresses north of the river. The city "was still inhabited by many Christians" at this point. In 1065-6 and 1066-7,
7225-557: Was used in the manufacture of tools during the Stone Age as it splits into thin, sharp splinters called flakes or blades (depending on the shape) when struck by another hard object (such as a hammerstone made of another material). This process is referred to as knapping . Flint mining is attested since the Paleolithic , but became more common since the Neolithic (Michelsberg culture, Funnelbeaker culture ). In Europe, some of
