Ross Island, Killarney
Ross Island is a claw-shaped peninsula in Killarney National Park, County Kerry. Ross Castle is located here and it is also the site of abandoned copper mines, including some believed to be the earliest in north-western Europe. Copper extraction on the site is believed to be the source of the first known Irish Pre-Bronze Age metalwork, namely copper axe heads, halberds and knife/dagger blades dating from 2,400 - 2,200 BC. These finds have been distributed throughout Ireland and in the West of Britain - in South Britain the metalwork was imported from across the English Channel.p142-146, Richard Bradley ''The prehistory of Britain and Ireland,'' Cambridge University Press, 2007, Excavations of the site have unearthed both mining operations and a smelting camp where the Copper ore was processed into a type of metal distinctive enough to be traced to these early tools. As there is no evidence that the complex technology had developed spontaneously, this early metallurgy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governors Rock, Ross Island, Lough Leane (geograph 4487175)
A governor is an administrative leader and head of a polity or political region, ranking under the head of state and in some cases, such as governors-general, as the head of state's official representative. Depending on the type of political region or polity, a ''governor'' may be either appointed or elected, and the governor's powers can vary significantly, depending on the public laws in place locally. The adjective pertaining to a governor is gubernatorial, from the Latin root ''gubernare''. Ancient empires Pre-Roman empires Though the legal and administrative framework of provinces, each administrated by a governor, was created by the Romans, the term ''governor'' has been a convenient term for historians to describe similar systems in antiquity. Indeed, many regions of the pre-Roman antiquity were ultimately replaced by Roman 'standardized' provincial governments after their conquest by Rome.

Killarney National Park
Killarney National Park ( ga, Páirc Náisiúnta Chill Airne), near the town of Killarney, County Kerry, was the first national park in Ireland, created when the Muckross Estate was donated to the Irish Free State in 1932. The park has since been substantially expanded and encompasses over 102.89 km2 (25,425 acres) of diverse ecology, including the Lakes of Killarney, oak and yew woodlands of international importance, and mountain peaks. It has the only red deer herd on mainland Ireland and the most extensive covering of native forest remaining in Ireland. The park is of high ecological value because of the quality, diversity, and extensiveness of many of its habitats and the wide variety of species that they accommodate, some of which are rare. The park was designated a UNESCO Biosphere Reserve in 1981. The park forms part of a Special Area of Conservation and a Special Protection Area. The National Parks and Wildlife Service is responsible for the management and adm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ross Castle
Ross Castle ( ga, Caisleán an Rois) is a 15th-century tower house and keep on the edge of Lough Leane, in Killarney National Park, County Kerry, Ireland. It is the ancestral home of the Chiefs of the Clan O'Donoghue, later associated with the Brownes of Killarney. The castle is operated by the Office of Public Works, and is open to the public seasonally with guided tours. History Ross Castle was built in the late 15th century by local ruling clan the O'Donoghues Mór (Ross), though ownership changed hands during the Second Desmond Rebellion of the 1580s to the MacCarthy Mór. He then leased the castle and the lands to Sir Valentine Browne, ancestor of the Earls of Kenmare. The castle was amongst the last to surrender to Oliver Cromwell's Roundheads during the Irish Confederate Wars, and was only taken when artillery was brought by boat via the River Laune. Lord Muskerry (MacCarthy) held the castle against Edmund Ludlow who marched to Ross with 4,000 foot-soldiers and 200 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Extraction
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Age
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 ...

Halberds
A halberd (also called halbard, halbert or Swiss voulge) is a two-handed pole weapon that came to prominent use during the 13th, 14th, 15th, and 16th centuries. The word ''halberd'' is cognate with the German word ''Hellebarde'', deriving from Middle High German ''halm'' (handle) and ''barte'' (battleaxe) joined to form ''helmbarte''. Troops that used the weapon were called halberdiers. The halberd consists of an axe blade topped with a spike mounted on a long shaft. It always has a hook or thorn on the back side of the axe blade for grappling mounted combatants. It is very similar to certain forms of the voulge in design and usage. The halberd was usually 1.5 to 1.8 metres (5 to 6 feet) long. The word has also been used to describe a weapon of the Early Bronze Age in Western Europe. This consisted of a blade mounted on a pole at a right angle. History The halberd was inexpensive to produce and very versatile in battle. As the halberd was eventually refined, its point was mor ...

Prehistoric Ireland
The prehistory of Ireland has been pieced together from archaeological evidence, which has grown at an increasing rate over the last decades. It begins with the first evidence of permanent human residence in Ireland around 10,500 BC (although there is evidence of human presence as early as 31,000 BC) and finishes with the start of the historical record around 400 AD. Both the beginning and end dates of the period are later than for much of Europe and all of the Near East. The prehistoric period covers the Palaeolithic, Mesolithic, Neolithic, Bronze Age and Iron Age societies of Ireland. For much of Europe, the historical record begins when the Romans invaded; as Ireland was not invaded by the Romans its historical record starts later, with the coming of Christianity. The two periods that have left the most spectacular groups of remains are the Neolithic, with its megalithic tombs, and the gold jewellery of the Bronze Age, when Ireland was a major centre of gold mining.

Copper Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
