She died in her twenties some 1,700 years ago, and is believed to have ruled over a desert valley in ancient Peru where her elaborately tattooed body was buried with weapons and gold objects. Using 3D imaging technology and forensics archaeology, the replica was based on the Lady of Cao's skull structure and ethnographic research and took 10 months to create, Peru's culture ministry said. The goal, said Culture Minister Salvador del Solar, was to bring the world closer to one of Peru's best archaeological finds and remind Peruvians of their rich cultural heritage.
