Known as the "High Priest of modern Sun-worshippers," Auguste Rollier created several outdoor sanatoria in the Swiss mountains for tubercular adults and children. Rollier advocated a total body treatment of natural sunlight, not simply for specific lesions on the surface but for a holistic, immune-boosting regeneration of the whole body. This highly artistic, anatomical drawing of a male figure illustrates his method of sectioning areas of the body according to sunlight exposure. This was a highly systematised, progressive process of exposure to sunlight, starting with the feet and always avoiding the head, for fear of sunstroke.
