San Xavier del Bac Mission is considered the finest example of mission architecture in the United States. Located nine miles south of Tucson, on the San Xavier Indian Reservation, it spiritual home to their people since 1797. It is currently difficult to do justice to its striking Moorish and Byzantine architecture with a photograph, since it is undergoing extensive restoration, and much of the exterior is under scaffold. To express the feeling of this magical place, I concentrated instead on its interior, which is covered with richly colored murals and life sized carvings of religious figures. The timing of our visit coincided with the flow of light through a mission window, projecting a softly shadowed cross on the opposite wall of the church. I moved my position so that the silhouetted hand of one of the carvings seems to be gesturing towards the symbol of its faith.
