Copper Age

From Wikipedia, the free encyclopedia

The Chalcolithic (Greek khalkos + lithos 'copper stone') period, also known as the Eneolithic (Aeneolithic) or Copper Age period, is a phase in the development of human culture in which the use of early metal tools appeared alongside the use of stone tools.

During 4300 - 3200 BC of chalcolithic period (Copper Age), Indus Valley Civilization area shows ceramic similarities with southern Turkmenistan and northern Iran which suggest considerable mobility and trade. ^[1]

The literature of European archaeology generally avoids the use of 'chalcolithic' (they prefer the term 'Copper Age'), while Middle-Eastern archaeologists regularly use it. The Copper Age began much earlier in the Middle East, while the transition from the European Copper Age to its own full-fledged Bronze Age is far more rapid.

The period is a transitional one outside of the traditional three-age system, and occurs between the neolithic and bronze age. It appears that copper was not widely exploited at first and that efforts in alloying it with tin and other metals began quite soon, making distinguishing distinct Chalcolithic cultures and periods difficult.

Because of this it is usually only applied by archaeologists in some parts of the world, mainly south-east Europe and Western and Central Asia where it appears around the 4th millennium BC. Less commonly, it is also applied to American civilizations which already used copper and copper alloys at the time of European conquest. The Old Copper Complex, located in present day Michigan and Wisconsin, is the oldest known site in the new world, and one of the oldest sites in the world, where copper was utilized for tools and other implements. Artefacts from these sites have been dated from 6000 to 3000 BC. [1]

The European Beaker people are often considered Chalcolithic as were the cultures which first adopted urbanisation in south west Asia. Many megaliths in Europe were erected during this period and it has been suggested that Proto-Indo-European linguistic unity dates to around the same time.

Knowledge of the use of copper was far wider spread than the metal itself. The European Battle Axe culture used stone axes modelled on copper axes, with imitation "mold marks" carved in the stone.

Ötzi the Iceman, found in the Ötztaler Alps and whose remains have been dated to about 3300 BC, carried a copper axe and flint knife. He appears to have been in a region of Europe which was transitioning through this period at that time.
