Faustino, 56, was struck by a lightning at the age of five in his hometown of Challapampa. This is how he gained his powers and became the shaman of Isla del Sol, a vast and mystical land that dominates the horizon on lake Titicaca, at more than 4000 meters above sea level on the Bolivian plateau. During his long walks he carries a small radio with him, so as not to feel lonely on the abandoned top of this island. He reaches his ceremonial sites, altars that were built all over this land 13,000 years ago by ancient cultures prior to the Tiahuanaco, in an era in which the sacred lake extended along the desert, once covered by jungle and temples.
