In another legend, Viracocha had two sons, Imahmana Viracocha and Tocapo Viracocha. After the Great Flood and the Creation, Viracocha sent his sons to visit the tribes to the northeast and northwest to determine if they still obeyed his commandments. Viracocha 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 Cusco (in modern-day Peru) and the Pacific seacoast, where they walked away across the water until they disappeared. The word "Viracocha" literally means "Sea Foam."
