Since the III Millennium ad, in Egypt are Grand, monumental buildings, temple complexes, irrigation and other facilities . Major construction of monumental stone buildings — wall and beam rack, which served as the basis of post-and-beam system . Of solid masonry were built with relatively simple funeral facilities — mastaba (bench), and then more complex — the ziggurats and pyramids ; post-and-beam system was used to build temples.
The Egyptians had carved huge stone blocks, which turned into obelisks, pillars and columns equal to the height of three, four storey building. Individual stone blocks were hewn diagonalise to each other without mortar. The unfolding of these blocks post-and-beam system acquired a different art form, which gradually turned into the constructive strict proportional composition (Fig. 1, a), later to be known as the order (. In the development of the Egyptian order is most clearly formed columns (pillars) and in particular the heads (capitals) (Fig. 1,b). Continue reading
“History, carved in stone,” it’s a common expression is fully applicable to the Metropolitan Museum-reserve “Kolomenskoye”. The snow-white Church of the ascension built in the XVI century the Grand Duke Vasily III. Luxurious Royal gates built in the reign of Alexei Mikhailovich.

Usually the edges of the arch emphasized the projecting rows of stones, and the use of Lancet arches to maintain the arches that were known in previous periods. But together these and other parts of the Gothic design has received a new Boolean value.
Scheme of ribbed vault
In Gothic has changed the system of a masonry ribbed vault. The ribs are now completed with the erection of the arch, and preceded him. 4 support was originally connected jaw arches (the arches at the ends of the arch), then threw two diagonal arches of ogive. This design was the skeleton of a future set. Forming the arch are called ribs. They were designed to bear and seal Stripping posted from lightweight slabs of stone. Ribbed arch favorably with a massive Romanesque by the fact that the point of application of the forces of gravity and thrust has Continue reading
