Another legend however states Manco Cápac was the son of Viracocha.
Myths Associated with Viracocha Creation Myths:
Viracocha created the universe, sun, moon and stars, time (by commanding the sun to move over the sky) and civilization itself. At first, the Earth was populated by a handful of giants made when he breathed life into stones. These beings defied Viracocha’s Rule Which Must Be Obeyed and were then wiped out by a giant vengeful storm/great flood (known as Unu Pachakuti). Then Viracocha went to Lake Titicaca and commanded the Sun and Moon to rise from the waters and tried for a second time to create civilization. (Sometimes it is said that he himself rose from this lake as well or sometimes the cave of Pacaritambo to bring forth light into this world). At Tiwanaku (also known as the center of the world) he carved the names and locations of every tribe and nation on a great piece of stone, spread the people he created and bid his servants to create civilization as we know it.
After creating civilization, he wandered the Earth disguised as a beggar, teaching his new creations the basics of civilization, as well as working numerous miracles.
Eventually, Viracocha disappeared by walking on the water/across the ocean.
Viracocha himself fathered the first eight civilized human beings.
Viracocha had two sons, Imahmana Viracocha and Tocapo Virachocha. After the Great Flood and the Creation, he sent his sons to visit the tribes to the Northeast and Northwest to determine if they still obeyed his commandments. Viracocha himself traveled North. During their journey, Imaymana and Tocapo gave names to all the trees, flowers, fruits and herbs. They also taught the tribes which of these were edible, which had medicinal properties, and which were poisonous. Eventually, Viracocha, Tocapo and Imahmana arrived at Cuzco (in modern day Peru) and the Pacific seacoast where they walked across the water until they disappeared.
He still walks the Earth at times disguised as a beggar to check up on the state of the world which usually causes him to cry. One day, if we become too wicked, his tears will cause a flood of total destruction.
Much like King Arthur, it was thought that Viracocha would re-appear in times of trouble.
Pedro Sarmiento de Gamboa noted that Viracocha was described as "a man of medium height, white and dressed in a white robe like an alb secured round the waist, and that he carried a staff and a book in his hands."
Representation of Viracocha at Ollantaytambo:
According to local myth, a representation of Viracocha – ‘The Creator of Civilization’ is shown in the small village of Ollantaytambo, Southern Peru (located along the Urubamba Valley, also known as the Sacred Valley of the Incas). Facing the ancient Inca ruins of Ollantaytambo in the rock face of 'Cerro Pinkuylluna' is the 140 meter high figure of Wiracocha. The angry looking formation of his face is made up of indentations that form the eyes and mouth, whilst a protruding carved rock denotes the nose. Inca ruins built on top of the face are also considered to represent a crown on his head. Artist impressions of the rock face also include a heavy beard and a large sack upon his shoulders.
