The ancient building techniques. Fixtures and cultured marble
More than six years have a blog devoted to the issues of ancient history. One of the themes is the study of ancient building techniques. Not everything was primitive then, as it seems at first glance, as they say the textbooks. In this topic, there is much to ponder.
It turns out that there are many examples where in the elements of ancient buildings visible fittings. Yes, metal, even and smooth, but the fittings. Which for historical periods, which include facilities - should not be. Because there was not that rolling mills, but even in such a quantity of iron.
Oh, and the very existence of the alleged reinforcement structure of rock, says that it is not natural rocks and artificial. Die-cast marble, for example. This was discussed in a separate article. And this article I want to open section "Ancient building technologies."
I take a look a few examples of the presence of reinforcement in the ancient buildings:
Marble columns. Reinforcing mesh at the base of the columns and trim. In this case, it plays a role just as the plaster grid framework. The photos below shows that smooth fittings, i.e. does not work as a reinforcement, concrete, for it does not cling at tensile strains. And it is necessary to hold the outer layer of the substrate solution. Solution, simulating marble. This technology is not described in the history books.
View close-up. Perhaps this is not ancient antique columns from the Bronze Age, and the reconstruction of the late 19th century., When they tried to restore something of the destroyed ancient buildings. Fittings, by the way, like in appearance was to the 19th century. In laying the ruined buildings of the 19th century churches. It can often be seen just such a smooth fitting.
There are more fantastic hypothesis: the antiquity did not end in the year, we are told the story. And there is reason to. During the excavations at Pompeii have been found quite medieval ironwork, which in antiquity not carry. On the Web you can find the article "The Last Days of Pompeii."
Another example: the ancient Gippos on the territory of modern Israel
Armature sticking out from the column. metal yield place to the increase:
It's not like a metal rod driven into the column. Although the photos on this 100% I do not presume to argue.
Iron rods in buildings Palmyra
Most likely, it was some kind of plaster artificial conglomerate that archaeologists call limestone. Rods themselves - covering, which is attached to formwork. Which remained after casting.
During the excavation of the abbey was found destroyed the statue, which sticks out from fittings.
If this artificial marble, it is still in the 19th century. known compounds that mimic natural rocks. Here is an excerpt from the book I.Sinelnikova "artificial marble":
A huge number of recipes for imitation, under the natural rock can be found in the book "Handbook of craftsman", 1931.
Visible rusted armature to fall off from the surface of age. Maybe the rust expands, chipped portion of the block.
Again, I have two versions: either reconstruction or antiquity is not so ancient times with the presence of then part of the modern technologies of construction and metal melting.
And finally a very interesting example of St. Petersburg:
Granite pillars on the quay (or one of the channels). Location unknown. The photograph on the left is visible cleavage column tops. And it is bent tube. The fact is that with a bend of the pipe can not be put in a post hole. In this position, the metallic enclosure can be filled only. But this granite!
Or city builders were able to simulate granite rock? Why are not preserved such recipes? Pour only on the basis of cement, gypsum and polymers (resins and acrylics). Questions in this regard, there are many.
