Uwe Carlson, Dipl.-Ing. (Civil Engineer * 1939) worked professionally in Peru in the 1970’s and 1080’s, gaining interest in the archeology of the country. During these years and during many later trips he explored, studied, and reflected on the country’s ancient cultures. He has since put forward a rigorous hypothesis for interpreting the iconography of the reliefs, wall paintings, textile and other art objects. In his interpretation, the divine images together with their accompanying symbolism bear a direct relation to the water management and cultural engineering of that time.
