Umm El-Marra
Umm el-Marra, ( ar, أم المرى), east of modern Aleppo in the Jabbul Plain of northern Syria, was one of the ancient Near East's oldest cities, located on a crossroads of two trade routes northwest of Ebla, in a landscape that was much more fertile than it is today. Possibly this is the city of Tuba mentioned in Egyptian inscriptions listing cities that were defeated or destroyed in the Pharaoh Thutmose III's north Syrian campaign. The city of Tuba is also mentioned in epigraphic remains from Ebla, Mari, and Alalakh. History Umm el-Marra probably had three to five thousand inhabitants between 2800 BCE and about 2100/2000 BCE, when Tuba and other cities in the Jabbul Plain experienced a mysterious collapse of central authority that lasted about 200 years. Partial answers to the question, why these early centers were so brittle, may lie in the effects of sustained drought on overstressed primitive agriculture.

Syria
Syria ( ar, سُورِيَا or سُورِيَة, translit=Sūriyā), officially the Syrian Arab Republic ( ar, الجمهورية العربية السورية, al-Jumhūrīyah al-ʻArabīyah as-Sūrīyah), is a Western Asian country located in the Eastern Mediterranean and the Levant. It is a unitary republic that consists of 14 governorates (subdivisions), and is bordered by the Mediterranean Sea to the west, Turkey to the north, Iraq to the east and southeast, Jordan to the south, and Israel and Lebanon to the southwest. Cyprus lies to the west across the Mediterranean Sea. A country of fertile plains, high mountains, and deserts, Syria is home to diverse ethnic and religious groups, including the majority Syrian Arabs, Kurds, Turkmens, Assyrians, Armenians, Circassians, Albanians, and Greeks. Religious groups include Muslims, Christians, Alawites, Druze, and Yazidis. The capital and largest city of Syria is Damascus. Arabs are the largest ethnic group, and Mu ...

Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze Age Sites In Syria
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability. The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Cities Of The Ancient Near East
The earliest cities in history were in the ancient Near East, an area covering roughly that of the modern Middle East: its history began in the 4th millennium BC and ended, depending on the interpretation of the term, either with the conquest by the Achaemenid Empire in the 6th century BC or with that by Alexander the Great in the 4th century BC. The largest cities of the Bronze Age Near East housed several tens of thousands of people. Memphis in the Early Bronze Age, with some 30,000 inhabitants, was the largest city of the time by far. Ebla is estimated to have had a population of 40,000 inhabitants in the Intermediate Bronze age. Ur in the Middle Bronze Age is estimated to have had some 65,000 inhabitants; Babylon in the Late Bronze Age similarly had a population of some 50,000–60,000. Niniveh had some 20,000–30,000, reaching 100,000 only in the Iron Age (around 700 BC). In Akkadian and Hittite orthography, URU became a determinative sign denoting a city, or combi ...

Kunga (equid)
The kunga was a Hybrid (biology), hybrid equid that was used as a draft animal in ancient Syria and Mesopotamia, where it also served as an economic and political status symbol. Cuneiform writings from as early as the mid-third millennium BCE describe the animal as a hybrid but do not provide the precise taxonomical nature of the breeding that produced it. Modern paleogenomics has revealed it to have been the offspring of a female domesticated donkey and a wild male Syrian wild ass. They fell out of favor after the introduction of domesticated horses into the region at the end of the 3rd millennium BCE. Elite equids Third-millennium BCE cuneiform from the kingdom of Ebla and the Mesopotamian region of Diyala name several types of equids (''ANŠE'', ), including one specified as the ''kúnga'' (''ANŠE BAR.AN'', ), which appear between about 2600 and 2000 BCE. These expensive animals, highly valued by the elite, were purpose-bred at Tell Brak, Nagar, the rulers of which used the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geochemistry
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology. History The term ''geochemistry'' was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838: "a comparative geochemistry ought to be launched, before geognosy can become geology, and before the mystery of the genesis of our planets and their inorganic matter may be revealed." However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. Geochemistry emerged as a separate discipline after ...

Hellenistic
In Classical antiquity, the Hellenistic period covers the time in Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Egypt the following year. The Ancient Greek word ''Hellas'' (, ''Hellás'') was gradually recognized as the name for Greece, from which the word ''Hellenistic'' was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great. After the Macedonian invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout south-west Asia ( Seleucid Empire, Kingdom of Pergamon), north-east Africa ( Ptolemaic Kingdom) and South Asia ( Greco-Bactrian Kingdom, Indo-Gree ...

Aleppo Governorate
Aleppo Governorate ( ar, محافظة حلب / ALA-LC: ''Muḥāfaẓat Ḥalab'' / ) is one of the fourteen governorates of Syria. It is the most populous governorate in Syria with a population of more than 4,867,000 (2011 Est.), almost 23% of the total population of Syria. The governorate is the fifth in area with an area of , or 18,498 sq. km, about 10% of the total area of Syria. The capital is the city of Aleppo. History Ancient In Classical Antiquity, the region was made up of three regions: Chalybonitis (with its centre at Chalybon or Aleppo), Chalcidice (with its center at Qinnasrīn العيس), and Cyrrhestica (with its center at Cyrrhus النبي حوري). This was the most fertile and populated region in Syria. Under the Romans the region was made in 193 CE part of the province of Coele Syria or Magna Syria, which was ruled from Antioch. The province of Euphratensis was established in the 4th century CE in the east, its centre was Hierapolis Bambyce (Manbij). Under th ...
