India has always been associated by most Europeans with something mystical and even fabulous, as has happened since the time of Alexander the Great, and this was the case in later eras - geographical discoveries or Napoleonic wars. The century KhІKh raised on the shield the question of the ancestral home of the Aryans - the heroes of the ancient Indian legends "Mahabharata" and "Ramayana," which, as science has proven, were the ancestors of all Indo-European peoples. Well, lovers of historical mysteries for many decades worried about the fate of the most famous precious stones in the history of mankind, whose homeland was the same India. Our book, intended for the widest circle of readers, tells about all this.
