  skos:definition "The Copper Age, or Chalcolithic time period, generally refers to circa5000 BCE to 2000 BCE. This typology was initiated by Dane Christian Jurgensen Thomsen in 1807 as a three-age system of classifying human prehistory based on toolmaking technologies (i.e., Stone Age, Bronze Age, and Iron Age). These categories were later refined by John Lubbock in 1865. [Source: Encyclopedia of Anthropology; Copper Age]"@en ;
