A0047: How were the megalithic stones of the Inca fortress Sacsayhuaman near Cuzco shaped?

They were not chiseled, but formed in clay by clay-like earth. They received their metallic coating through a series of refinements that are no longer known today. Let us take the large main stones at the gate, where several layers of clay were placed on top of one another, pressed and then brought into their final shape. The burning of the big stones was done on site. Traces of it can still be found today and the sound carrier for the stones is only a few kilometers away. The mystery of these stones is great, but if the clay is properly understood, many, not all, but many puzzles will be solved.
