Byzantine Agriculture
The Byzantine economy was among the most robust economies in the Mediterranean and the world for many centuries. Constantinople was a prime hub in a trading network that at various times extended across nearly all of Eurasia and North Africa. It could be argued that, up until the arrival of the Arabs in the 7th century, the Eastern Roman Empire had the most powerful economy in the world. The Arab conquests, however, would represent a substantial reversal of fortunes contributing to a period of decline and stagnation. Constantine V's reforms (c. 765) marked the beginning of a revival that continued until 1204. From the 10th century until the end of the 12th, the Byzantine Empire projected an image of luxury, and travelers were impressed by the wealth accumulated in the capital. All this changed with the arrival of the Fourth Crusade, which was an economic catastrophe. The Palaiologoi tried to revive the economy, but the late Byzantine state would not gain full control of either the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia Minor
Anatolia (), also known as Asia Minor, is a peninsula in West Asia that makes up the majority of the land area of Turkey. It is the westernmost protrusion of Asia and is geographically bounded by the Mediterranean Sea to the south, the Aegean Sea to the west, the Turkish Straits to the northwest, and the Black Sea to the north. The eastern and southeastern limits have been expanded either to the entirety of Asiatic Turkey or to an imprecise line from the Black Sea to the Gulf of Alexandretta. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus and the Dardanelles, and separates Anatolia from Thrace in Southeast Europe. During the Neolithic, Anatolia was an early centre for the development of farming after it originated in the adjacent Fertile Crescent. Beginning around 9,000 years ago, there was a major migration of Anatolian Neolithic Farmers into Neolithic Europe, Europe, with their descendants coming to dominate the continent a ...

Pestle
A mortar and pestle is a set of two simple tools used to prepare ingredients or substances by compression (physics), crushing and shear force, grinding them into a fine Paste (rheology), paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hardwood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, or rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since the Stone Age; today they are typically associated with the pharmacy profession due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making Grog (clay), grog; ...

Wheel
A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for a wheel to rotate, a Moment (physics), moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque. Terminology The English word '':wikt:wheel, wheel'' comes from the Old English word , from Proto-Germanic language, Proto-Germanic , ...

Works And Days
''Works and Days'' ()The ''Works and Days'' is sometimes called by the Latin translation of the title, ''Opera et Dies''. Common abbreviations are ''WD'' and ''Op'' for ''Opera''. is a didactic poem written by ancient Greek poet Hesiod around 700 BC. It is in dactylic hexameter and contains 828 lines. At its center, the ''Works and Days'' is a Almanac, farmer's almanac in which Hesiod instructs his brother Perses in the agricultural arts. Scholars have seen this work against a background of agrarian crisis in mainland Greece, which inspired a wave of Greek colonies, colonial expeditions in search of new land. In the poem, Hesiod also offers his brother extensive moralizing advice on how he should live his life. ''Works and Days'' is perhaps best known for its two mythological aetiology, aetiologies for the toil and pain that define the human condition—the story of Prometheus and Pandora, and the so-called Ages of Man, Myth of Five Ages.

Hesiod
Hesiod ( or ; ''Hēsíodos''; ) was an ancient Greece, Greek poet generally thought to have been active between 750 and 650 BC, around the same time as Homer.M. L. West, ''Hesiod: Theogony'', Oxford University Press (1966), p. 40.Jasper Griffin, "Greek Myth and Hesiod", J.Boardman, J.Griffin and O. Murray (eds.), ''The Oxford History of the Classical World'', Oxford University Press (1986), p. 88. Several of Hesiod's works have survived in their entirety. Among these are ''Theogony'', which tells the origins of the gods, their lineages, and the events that led to Zeus's rise to power, and ''Works and Days'', a poem that describes the five Ages of Man, offers advice and wisdom, and includes myths such as Pandora's box. Hesiod is generally regarded by Western authors as 'the first written poet in the Western tradition to regard himself as an individual persona with an active role to play in his subject.' Ancient authors credited Hesiod and Homer with establishing Greek relig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illuminated Manuscripts
An illuminated manuscript is a formally prepared manuscript, document where the text is decorated with flourishes such as marginalia, borders and Miniature (illuminated manuscript), miniature illustrations. Often used in the Roman Catholic Church for prayers and liturgical books such as psalters and courtly literature, the practice continued into secular texts from the 13th century onward and typically include proclamations, enrolled bills, laws, charters, inventories, and deeds. The earliest surviving illuminated manuscripts are a small number from late antiquity, and date from between 400 and 600 CE. Examples include the Vergilius Romanus, Vergilius Vaticanus, and the Rossano Gospels. The majority of extant manuscripts are from the Middle Ages, although many survive from the Renaissance. While Islamic manuscripts can also be called illuminated and use essentially the same techniques, comparable Far Eastern and Mesoamerican works are described as ''painted''. Most manuscripts, ...

Arabic Numerals
The ten Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) are the most commonly used symbols for writing numbers. The term often also implies a positional notation number with a decimal base, in particular when contrasted with Roman numerals. However the symbols are also used to write numbers in other bases, such as octal, as well as non-numerical information such as trademarks or license plate identifiers. They are also called Western Arabic numerals, Western digits, European digits, Ghubār numerals, or Hindu–Arabic numerals due to positional notation (but not these digits) originating in India. The ''Oxford English Dictionary'' uses lowercase ''Arabic numerals'' while using the fully capitalized term ''Arabic Numerals'' for Eastern Arabic numerals. In contemporary society, the terms ''digits'', ''numbers'', and ''numerals'' often implies only these symbols, although it can only be inferred from context. Europeans first learned of Arabic numerals , though their spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windmill
A windmill is a machine operated by the force of wind acting on vanes or sails to mill grain (gristmills), pump water, generate electricity, or drive other machinery. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines have been known earlier, the Babylonian emperor Hammurabi had used wind mill power for his irrigation project in Mesopotamia in the 17th century BC. Later, Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen zur westlichen Windmühle", ''Archiv für Kulturgeschichte'', Vol. 77, Issue 1 (1995), pp. 1–30 (10f.) ...

Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically, mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind ( windmill) or water (watermill). In the modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
