Nuragic Period
The Nuragic civilization, also known as the Nuragic culture, was a civilization or culture on Sardinia (Italy), the second largest island in the Mediterranean Sea, which lasted from the 18th century BC (Middle Bronze Age) (or from the 23rd century BC ) up to the Roman colonization in 238 BC. Others date the culture as lasting at least until the 2nd century AD and in some areas, namely the Barbagia, to the 6th century AD or possibly even to the 11th century AD. The adjective "Nuragic" is neither an autonym nor an ethnonym. It derives from the island's most characteristic monument, the nuraghe, a tower-fortress type of construction the ancient Sardinians built in large numbers starting from about 1800 BC. Today more than 7,000 nuraghes dot the Sardinian landscape. No written records of this civilization have been discovered, apart from a few possible short epigraphic documents belonging to the last stages of the Nuragic civilization. The only written inf ...

Paleolithic
The Paleolithic or Palaeolithic (), also called the Old Stone Age (from Greek: παλαιός ''palaios'', "old" and λίθος ''lithos'', "stone"), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 cal BP. The Paleolithic Age in Europe preceded the Mesolithic Age, although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, includ ...

Hypogeum
A hypogeum or hypogaeum (plural hypogea or hypogaea, pronounced ; literally meaning "underground", from Greek language, Greek ''hypo'' (under) and ''ghê'' (earth)) is an underground temple or tomb. Hypogea will often contain niche (architecture), niches for cremated human remains or Loculus (architecture), loculi for buried remains. Occasionally tombs of this type are referred to as built tombs. The term ''hypogeum'' can also refer to any antique building or part of building built below ground such as the series of tunnels under the Colosseum which held slaves (particularly enemy captives) and animals while keeping them ready to fight in the gladiatorial games. The animals and slaves could be let up through trapdoors under the sand-covered arena at any time during a fight. Examples An early example of a hypogeum is found at the Minoan civilization, Minoan Bronze Age site of Knossos on Crete. Hogan notes this underground vault was of a beehive shape and cut into the soft r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolmen
A dolmen () or portal tomb is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the early Neolithic (40003000 BCE) and were sometimes covered with earth or smaller stones to form a tumulus (burial mound). Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance.Murphy (1997), 43 In many instances, the covering has eroded away, leaving only the stone "skeleton". The Korean Peninsula is home to the world's highest concentration of dolmens,UNESCO World Heritage List. "Gochang, Hwasun and Ganghwa Dolmen Sites." https://whc.unesco.org/en/list/977 including "cemeteries" consisting of 30–100 examples located in close proximity to each other; with over 35,000 dolmens, Korea alone (for unknown reasons) accounts for approximately 40% of the global total. History It remains unclear when, why and by whom the earliest dolmens were mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menhir
A menhir (from Brittonic languages: ''maen'' or ''men'', "stone" and ''hir'' or ''hîr'', "long"), standing stone, orthostat, or lith is a large human-made upright stone, typically dating from the European middle Bronze Age. They can be found individually as monoliths, or as part of a group of similar stones. Menhirs' size can vary considerably, but they often taper toward the top. They are widely distributed across Europe, Africa and Asia, but are most numerous in Western Europe; particularly in Ireland, Great Britain, and Brittany, where there are about 50,000 examples, and northwestern France, where there are some 1,200 further examples. Standing stones are usually difficult to date. They were constructed during many different periods across pre-history as part of the larger megalithic cultures in Europe and near areas. Some menhirs stand next to buildings that have an early or current religious significance. One example is the South Zeal Menhir in Devon, which formed th ...

Chalcolithic Period
The Copper Age, also called the Chalcolithic (; from grc-gre, χαλκός ''khalkós'', "copper" and ''líthos'', "stone") or (A)eneolithic (from Latin '' aeneus'' "of copper"), is an archaeological period characterized by regular human manipulation of copper, but prior to the discovery of bronze alloys. Modern researchers consider the period as a subset of the broader Neolithic, but earlier scholars defined it as a transitional period between the Neolithic and the Bronze Age. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from (7000 BP). The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late In the Ancient Near East the Copper Age covered about the same period, beginning in the late and lasting for about a millennium before it gave rise to the Early Bronze Age.

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...

Ozieri Culture
The Ozieri culture (or San Michele culture) was a prehistoric pre-Nuragic culture that occupied Sardinia from c. 3200 to 2800 BCE. The Ozieri was the culmination of the island's Neolithic culture and takes its name from the locality where early findings connected with it have been found, the cave of San Michele near Ozieri, in northern Sardinia. The Ozieri existed contemporaneously with the Arzachena culture, sharing some similarities, and its influence also extended to nearby Corsica. History Archaeological excavations have identified some 200 Ozieri sites, located both in plain and mountain areas, but with a preference for low ridges, and largely organized around an economy of Hunter-gatherers mixed with an initial presence of husbandry and agriculture. The settlements consisted of small stone huts, with a circular (rarely rectangular) wall supporting a wooden frame with a ceiling of boughs. One, near Sestu, consisted of 60 huts. Another, near Mogoro, included 267 huts, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglona
Anglona is a historical region of northern Sardinia, Italy. Its main center is Castelsardo. Geography Anglona is bounded by the sea northwards, from east by the Coghinas river, from south by Monte Sassu and from west by the Silis River and the Monte Pilosu. The territory is characterized by a prevalence of hills, with small plateaus of volcanic or limestone origin, lying over a tuff base. The coast shows beaches intermingled with rocky sectors. Economy Economy is mostly based on agriculture, especially after the reclamation of the lower Coghinas valley during the 1920s, which has saved the fertile area from floods. The main crops are artichokes and tomatoes The tomato is the edible Berry (botany), berry of the plant ''Solanum lycopersicum'', commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Mexican Nahuatl word gave rise to th .... Starting from the 1970s, the coastal communes have developed a flou ...
