Secondary Products Revolution
Andrew Sherratt's model of a secondary products revolution involved a widespread and broadly contemporaneous set of innovations in Old World farming. The use of domestic animals for primary carcass products (meat) was broadened from the 4th–3rd millennia BCE (c. Middle Chalcolithic) to include exploitation for renewable 'secondary' products: milk, wool, traction (the use of animals to drag ploughs in agriculture), riding and pack transport. The SPR model incorporates two key elements: # the discovery and diffusion of secondary products innovations # their systematic application, leading to a transformation of Eurasian economy and society Many of these innovations first appeared in the Near East during the fourth millennium BCE and spread to Europe and the rest of Asia soon afterwards. They appeared in Europe by the beginning of the third millennium BCE. These innovations became available in Europe due to the westwards diffusion of new species (horse, donkey), breeds (e.g. w ...

Andrew Sherratt
Andrew George Sherratt (8 May 1946 – 24 February 2006) was an English archaeologist, one of the most influential of his generation. He was best known for his theory of the secondary products revolution. Early life and education Sherratt was born in Oldham, Lancashire on 8 May 1946. From 1965, he studied archaeology and anthropology at Peterhouse, Cambridge University, completing his degree in 1968. He received his PhD from Cambridge in 1976, writing his thesis on ''The Beginning of the Bronze Age in south-east Europe''. Academic career He moved to Oxford, having been appointed Assistant Keeper of Antiquities at the Ashmolean Museum in 1973. He was a reader at the University of Oxford from 1997 and Professor from 2002. Oxford remained his academic home until 2005, when he took up a professorship at the University of Sheffield. Sherratt travelled widely and received international recognition for his work. He was invited to give the prestigious Human Context and Society lec ...

Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, '' Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Of Marmara
The Sea of Marmara,; grc, Προποντίς, Προποντίδα, Propontís, Propontída also known as the Marmara Sea, is an inland sea located entirely within the borders of Turkey. It connects the Black Sea to the Aegean Sea via the Bosporus and Dardanelles straits, separating the country's European and Asian sides. The Sea of Marmara is a small sea with an area of , and dimensions of . Its greatest depth is . Name The Sea of Marmara is named after the largest island to its south side which is called Marmara Island because it is rich in marble (Greek (''mármaron'') "marble)." In classical antiquity it was known as the Propontis, which is derived from the Greek words ''pro-'' (before) and ''pontos'' (sea) and reflects the fact that the Ancient Greeks used to sail through it to reach the Black Sea that they called Pontos. Mythology In Greek mythology, a storm on the Propontis brought the Argonauts back to an island they had left, precipitating a battle in whic ...

Terminus Ante Quem
''Terminus post quem'' ("limit after which", sometimes abbreviated to TPQ) and ''terminus ante quem'' ("limit before which", abbreviated to TAQ) specify the known limits of dating for events or items.. A ''terminus post quem'' is the earliest date the event may have happened or the item was in existence, and a ''terminus ante quem'' is the latest. An event may well have both a ''terminus post quem'' and a ''terminus ante quem'', in which case the limits of the possible range of dates are known at both ends, but many events have just one or the other. Similarly, ''terminus ad quem'' ("limit to which") is the latest possible date of a non-punctual event (period, era, etc.), while ''terminus a quo'' ("limit from which") is the earliest. The concepts are similar to those of upper and lower bounds in mathematics. These terms are often used in archaeological and historical studies, such as dating layers in excavated sites, coins, historical events, authors, inscriptions or texts wher ...

Iconography
Iconography, as a branch of art history, studies the identification, description and interpretation of the content of images: the subjects depicted, the particular compositions and details used to do so, and other elements that are distinct from artistic style. The word ''iconography'' comes from the Greek ("image") and ("to write" or ''to draw''). A secondary meaning (based on a non-standard translation of the Greek and Russian equivalent terms) is the production or study of the religious images, called "icons", in the Byzantine and Orthodox Christian tradition (see Icon). This usage is mostly found in works translated from languages such as Greek or Russian, with the correct term being "icon painting". In art history, "an iconography" may also mean a particular depiction of a subject in terms of the content of the image, such as the number of figures used, their placing and gestures. The term is also used in many academic fields other than art history, for example semioti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land ( rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals ( grains), vegetables, fruits, cooking oils, m ...

Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as " livestock") are released onto large vegetated outdoor lands ( pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastora ...

Ard (plough)
The ard, ard plough, or scratch plough is a simple light plough without a mouldboard. It is symmetrical on either side of its line of draft and is fitted with a symmetrical share that traces a shallow furrow but does not invert the soil. It began to be replaced in China by the heavy carruca turnplough in the 1st century, and in most of Europe from the 7th century. In its simplest form it resembles a hoe, consisting of a ''draft-pole'' (either composite or a single piece) pierced with a nearly vertical, wooden, spiked ''head'' (or ''stock'') which is dragged through the soil by draft animals and very rarely by people. The ard-head is at one end a ''stilt'' (handle) for steering and at the other a ''share'' (cutting blade) which gouges the surface ground. More sophisticated models have a composite pole, where the section attached to the head is called the ''draft-beam'', and the share may be made of stone or iron. Some have a cross-bar for handles or two separate stilts for handle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the 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 are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word '' wheel'' comes from the Old English word , from Proto-Germanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order (biology), order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and sheep milk, milk. A sheep's wool is the most widely used animal fiber, and is usually harvest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donkey
The domestic donkey is a hoofed mammal in the family Equidae, the same family as the horse. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries. A male donkey is known as a ''jack'' or ''jackass'', a female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a ''foal''. Jacks are often mated with female horses (mares) to produce ''mules''; the less common hybrid of a male horse (stallion) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
