Carlos Prado performing a coca ritual in Cochabamba, Bolivia, 2005. Photo by Vance Gellert from the "Smoke and Mirrors" exhibition at the Minneapolis Institute of the Arts. As a photographer and a scientist, Vance Gellert has traveled to Bolivia and Peru to observe native healing rituals, environments and plants. The photographs and actual healing objects from these journeys of discovery evoke a spirit of place, culture, and healing traditions. They transcend cultural differences to create a receptive and stimulating environment in which to consider new directions and methodology in health care. Gellert's exhibition illustrates how art can contribute to scientific understanding of our world.
