Rich deposits of metals, created by the dynamic geologic environment that built the rugged Andes Mountains, became intertwined with Andean cultures in the New World. The Incas and their ancestors created metal products primarily for aesthetic uses and for religious goods. This contrasts with Old World cultures, where the emphasis was on the mechanical properties of metals -- strength, hardness and sharpness—for tools and weapons.
