The legendary Viracocha brought civilization and enlightenment to the Peruvian Indians. Before his arrival, people lived in chaos, were naked, had no homes, and survived solely by foraging. Viracocha changed all of this, ushering in a golden age of civilization in Peru that included advancements in medicine, metallurgy, agriculture, livestock, and writing. With a compassionate heart, he taught the people rather than using force. He also introduced a profound knowledge of engineering and architecture to Peru. The Inca-style stone buildings in the city of Cusco showcase exceptional craftsmanship, but some of these structures were not built by the Incas; they are remnants of earlier civilizations. The Incas primarily contributed by restoring ancient buildings and maintaining the road network, rather than constructing new ones. The legendary Viracocha also sent 'apostles' to spread messages across the land, adding to the mystery surrounding the origins of Peruvian civilization.
