Economy Of Ancient Tamil Country
The economy of the ancient Tamil country ( Sangam era: 600 BCE – 300 CE) describes the ancient economy of a region in southern India that mostly covers the present-day states of Tamil Nadu and Kerala. The main economic activities were agriculture, weaving, pearl fishery, manufacturing and construction. Paddy was the most important crop; it was the staple cereal and served as a medium of exchange for inland trade. Pepper, sugarcane, millets, and various other cereals were other commonly grown crops. Madurai and Urayur were important centers for the textile industry; Korkai was the center of the pearl trade. Industrial activity flourished. Inland trading was conducted primarily through barter in busy market places by merchant associations and commercial lending institutions. Merchants formed associations that operated autonomously, without interference from the state. The people of ancient Tamil country engaged in brisk overseas trade with Rome; the trade reached a peak af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, 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 controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Grain Millet, Early Grain Fill, Tifton, 7-3-02
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached husk, hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantain (cooking), plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and mill (grinding), milled for flour or expeller pressing, pressed for Seed oil, oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains. Cereal and non-cereal grains In the grass family, a grain (narrowly defined) is a caryopsis, a fruit with its wall fused on to the single seed ...

Vertisol
A vertisol is a Soil Order in the USDA soil taxonomy and a Reference Soil Group in the World Reference Base for Soil Resources (WRB). It is also defined in many other soil classification systems. In the Australian Soil Classification it is called vertosol. The natural vegetation of vertisols is grassland, savanna, or grassy woodland. The heavy texture and unstable behaviour of the soil makes it difficult for many tree species to grow, and forest is uncommon. Composition Vertisols have a high content of expansive clay minerals (many of them belonging to the montmorillonites) that form deep cracks in drier seasons or years. In a phenomenon known as argillipedoturbation, alternate shrinking and swelling causes ''self-ploughing'', where the soil material consistently mixes itself, causing some vertisols to have an extremely deep A horizon and no B horizon. (A soil with no B horizon is called an ''A/C soil''). This heaving of the underlying material to the surface often create ...

Alluvial Soil
Alluvium (, ) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined '' alluvion'' (the French term for alluvium) as new land formed by deposition of ...

Sangam Landscape
The Sangam landscape (Tamil language, Tamil: அகத்திணை "inner classification") is the name given to a poetic device that was characteristic of love poetry in classical Tamil language, Tamil Sangam literature. The core of the device was the categorisation of poems into different ''tiṇai''s or modes, depending on the nature, location, mood and type of relationship represented by the poem. Each ''tiṇai'' was closely associated with a particular landscape, and imagery associated with that landscape—its flowers, trees, wildlife, people, climate and geography—was woven into the poem in such a way as to convey a mood, associated with one aspect of a romantic relationship. Symbolism Classical Tamil love poetry assigns the human experiences it describes, and in particular the subjective topics that those experiences relate to, to specific habitats. Every situation in the poems is described using themes in which the time, the place and the floral symbols of each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sangam Literature
The Sangam literature (Tamil language, Tamil: சங்க இலக்கியம், ''caṅka ilakkiyam''), historically known as 'the poetry of the noble ones' (Tamil language, Tamil: சான்றோர் செய்யுள், ''Cāṉṟōr ceyyuḷ''), connotes the early classical Tamil literature and is the earliest known literature of South India. The Tamil tradition links it to Legendary Tamil Sangams, legendary literary gatherings around Madurai in the ancient Pandya dynasty, Pandya kingdom. It is generally accepted by most scholars that the historical Sangam literature era, also known as the Sangam period, spanned from 100 BCE to 250 CE, on the basis of linguistic, epigraphic, archaeological, numismatic and historical data; though some scholars give a broader range of 300 BCE to 300 CE. The Eighteen Greater Texts (Patiṉeṇmēlkaṇakku), along with the Tamil grammar work Tolkāppiyam, Tolkappiyam, are collectively considered as Sangam literature. These tex ...

Tamil People
The Tamils ( ), also known by their endonym Tamilar, are a Dravidian ethnic group who natively speak the Tamil language and trace their ancestry mainly to the southern part of the Indian subcontinent. The Tamil language is one of the longest-surviving classical languages, with over two thousand years of written history, dating back to the Sangam period (between 300 BCE and 300 CE). Tamils constitute about 5.7% of the Indian population and form the majority in the South Indian state of Tamil Nadu and the union territory of Puducherry. They also form significant proportions of the populations in Sri Lanka (15.3%), Malaysia (7%) and Singapore (5%). Tamils have migrated world-wide since the 19th century CE and a significant population exists in South Africa, Mauritius, Fiji, as well as other regions such as the Southeast Asia, Middle East, Caribbean and parts of the Western World.

Agriculture
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Currency
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum#Numismatics, orichalcum and copper coinage. From its introduction during the Roman Republic, Republic, in the third century BC, through Roman Empire, Imperial times, Roman currency saw many changes in form, denomination, and composition. A feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued with Byzantine currency. Due to the economic power and longevity of the Roman state, Roman currency was widely used throughout western Eurasia and northern Africa from classical times into the Middle Ages. It served as a model for the currencies of the List of Muslim states and dynasties, Muslim caliphates and the European states during the Middle Ages and the Modern Era. Roman currency names survive today in many countries via the Carolingian monetary system, such as the dinar (from the ''denari ...

Topaz
Topaz is a silicate mineral made of aluminium, aluminum and fluorine with the chemical formula aluminium, Alsilicon, Sioxygen, O(fluorine, F, hydroxide, OH). It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden-brown to yellow-orange. Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple. Topaz is a nesosilicate mineral, and more specifically, an aluminosilicate mineral. It is one of the hardest naturally occurring minerals and has a relatively low index of refraction. It has the orthorhombic crystal system and a dipyramidial crystal class. It occurs in many places in the world. Some of the most popular places where topaz is sourced are Brazil and Russia. Topaz is often mined in open pit or alluvial settings. Etymology The word "topaz" is usually believed to be derived (via Old French: Topace and Latin: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
