I am very excited to show you this because this rock cutting technique is completely mindboggling, and I believe you have never seen this before, in any other ancient site. Look at the ceiling of this hallway, look at the shape of this ceiling, it is an arch, in architecture, we call this a vault. But something is very strange about these rocks, pay attention to the top most pieces of this ceiling. This is extraordinary, because these are actual arch shaped stone blocks made of solid sandstone. Ancient builders have actually taken solid sandstone blocks and converted them into curved arches. The top blocks are known as Keystones and the keystones of this hallway have been bent like pieces of rubber. If we horizontally tilt this picture, you can see how curved these arches are, the degree of curve is just incredible. But is this really unique? Throughout most ancient civilizations, arches have been used, in fact, Romans used arches more than 2000 years ago, but you are in for a surprise. Let us look at this underground tunnel recently found in Scotland, this was built 300 years after this temple, and at first glance, you think this is a good archway, but look at the top most blocks. There is not one keystone, but two of them, and the blocks are not curved, the builders have merely tried to give an appearance of an arch, these are 2 rectangular blocks with very little curves. Here is the ancient Olympic stadium in Greece, and look at this arch, again it looks like a nice curved arch, but when you zoom in, you realize that the blocks are actually just rectangular blocks and are merely arranged to give you the appearance of an arch. I have looked at many many examples of arches and vaults in ancient and medieval Europe and I am surprised that no true arches exist in Megalithic structures, meaning none of the top most blocks are actually curved as arches. But here, in this remote part of Cambodia, we see how ancient Hindus have bent rocks and created true arches. Forget ancient times, what about today, do we create true arches, today? This is an ancient vault in Greece, and the top blocks have fallen and have been repaired with new stone blocks, but again look, even the new blocks are actually rectangular blocks with very little curve. Why? Why is it such a problem to create arches, or curves in stone? Did ancient builders soften stone and create these perfect arches? If so, how did they convert hard sandstone into soft material? Hindus believe that rocks were softened using herbs, then cut into desired shapes, and the blocks became hardened again, after some time. People think of this as a strange theory, but think about this right? How do seeds grow on solid rock? Every once in a while, you will see the smallest seed beginning to gain roots on even the hardest rock. How is this possible? Because herbs and even seeds have natural acids like oxalic acid, which are quite strong. And they can soften even the hardest rocks, this is why you see seeds taking root and eventually demolishing even the largest stone structures. Ancient Cambodians must have definitely used some kind of herbs or acids to soften these stones. Otherwise making hundreds of identical stone arches is impossible. But this is not just a guess, there is actual evidence of acid treatment. Look at the corner stone of the ceiling, this is shocking, because this gigantic block has completely turned black, as though it was treated with some kind of acid or chemical. Look at the surface of this rock, it is full of ridges, as though it was damaged with some chemical, which has burnt the surface. Ancient builders definitely used herbs or some type of chemicals to soften stones. When I scrape on these sandstone blocks, I realize that their natural hardness has been altered. #Cambodia #AncientTechnology #PraveenMohan
