Pre-Hispanic peoples observed the universe as balancing and opposing forces, mind and spirit, earth and sky, life and death, feminine and masculine. However, it is among the Andean peoples that this philosophy is the most entrenched. They developed a structure of social behavior and thought that had a dual character, expressed symbolically through opposites in nature.
The Andean metalwork reveals a particular interest in geometry. Symmetrical compositions may suppose to reveal a deliberate search for order, harmony and balance. The Pastos people consider that women have something masculine and men have something feminine, thereby blurring the gender lines and seeing everyone as an important member of the society.
