text: Minerals of copper were known from ancient times. In Crete, little fragments of malachite and azurite were powdered and used as make up or to decorate ceramic as early as 6000 BCE.
  Therefore, the minerals were not collected because people were looking for copper but for virtues like those mentioned or simply because of its brightness and colour, but this knowledge of the minerals is critical since they already knew how to recognize them and where to collect them when, later, they started the systematic search for ores.
  Numerous examples of mines are known all over Europe, from the east: Rudna Glava (Serbia), Ai Bunar (Bulgaria); to the west: Mount Gabriel (Ireland), Great Orme, Alderley Edge (United Kingdom); crossing Central Europe: Mitterberg (Salzach, Austria), Neuchâtel (Switzerland), Cabrierés (France); to the south: Riotinto, Mola Alta de Serelles (Spain); and the Mediterranean: Corsica, Cyprus, and the Cyclades islands. It is remarkable that, usually, it is not a single mine but a complex, with a variable, large number of mineshafts, as in Rudna Glava (30) or Mount Gabriel (31).
