The BRONZE AGE (around the 2nd Millennium BC)
With the improvement of method of production, there are new tools made of copper and bronze. Occurs the first major social division of labor, increasing wealth inequality. Then the craft separated from agriculture, is the second major division of labor. All this played a crucial role in the development of civilization. In the Nile valley, in Mesopotamia and China established a slave system, the first class of the state. All this led to the development of different spheres of human spiritual activity.
The overwhelming significance of monumental architecture associated with the development of religious beliefs, the cult of ancestors and nature. These were megalithic structures – menhirs (gr. meg). – a large, lit – rock) – single cigar-shaped stone pillars with a height up to 20 m (Brittany, France); sometimes they stretched in parallel rows for several miles (“the Stone army” – the Caucasus, Armenia; the alley of menhirs in Brittany); Continue reading

To the rear of the junction she bent down. But then there is not a decorative treatment and targeted production of different size of stone for buildings. In the Macho Piccho in the mountains, also traces of stone extraction for construction. What tool/tools this was done will probably remain a mystery. From the analysis of the surveyed structures could be accurately determined that their builders could with equal ease to process stone of any kind in any spatial directions. For the ancients it was so easy and relaxed that is simply breathtaking and even imagination can not paint a picture of such works. Such are incredibly difficult to reproduce in the present. Ancient just cut out of rock blocks of the form that they desired and they were immediately used. The drilling installation – they can be used when making various holes, ubiquitous in all ancient complexes.
He could explain the perfectly smooth internal surface units in areas of the joint. However, what these settings could be hard to say. Its use could explain the treatment plots of whole rocks and mining rocks. Such processing methods can also be seen in the structural elements that seem to be poured concrete but are actually monolithic fragments of ancient buildings. Continue reading
Ancient technologies and structures: Peru
Blocks cut out of stone, perfectly adhere to each other. In the joints between two blocks do not pass even an ordinary sheet of paper or a credit card.
For binding the data blocks not used for the solution. Blocks attached by a snug fit and a three-dimensional structure of masonry.
In the video above, perfectly describes possible ways of working stone, but the actual acting method, which was used by the builders, no one knows.
This is due to the fact that the way to cut granite blocks directly from the rock and to Polish them and in modern technology.
Strikes and the high precision with which the blocks were made. Not only that, all of them are best fitted to each other, and have clear, straight edges.
In masonry blocks found rough and well polished. Unusual is that the last slightly protrude above the mass, although if they were worn in a natural way, it ought to be Vice versa. Continue reading
