Where the majestic Andes Mountains separate Amazon jungles from barren Pacific shores there was once a pageantry of vibrant cultures that flourished and vanished long before Europeans arrived.

Covering 3,000 years of Peruvian prehistory, examine how cultures reveal their natural and supernatural worlds through art and architecture, and how people who engaged in dire rituals left an artistic legacy unsurpassed in the ancient world.
