Natural stone has always been a crucial part of the material culture of the human race. Mankind faced the need to process stone as early as the beginning of its development.
During the earliest cultural-historical period, the stone age (approx. from 800 to 5 thousand years BC) stone was the main material used to make tools (axes, hoes), weapons (arrow tips, spears), ornaments and attributes symbolizing the meaning of human life, dwellings and religious monuments.
The great importance of stone for human life during the time of the primitive community gave the name of that age, the Paleolithic Age (from the Latin paleo old and lith stone), which started with the appearance of the first stone tools and ended with the discovery of copper during the Bronze Age.
Stone processing during the Paleolithic Age passed through a long evolution from the use of rough unprocessed implements to the invention of various cutting tools.
During that period man gradually acquired the manual operations for stone processing in the following technological-chronological sequence:
• dislodging and breaking off during the Early and Middle Paleolithic (800 鈥�35 thousand years BC);
• splitting and rough hewing during the Late Paleolithic (35 鈥� 10 thousand years BC);
• cutting, grinding and drilling holes during the Neolithic (10 鈥� 5 thousand years BC);
As late as the Bronze (4 鈥� 2 thousand years BC) and Iron Ages (2 鈥� 1 thousand years BC), when metal tools were invented, man managed to master the skill of processing the hardest rock material, i.e. granite.
