Emma Kunz was born into a family of Swiss weavers in 1892. Kunz who was loosely considered a visionary or spiritualist artist, created these complex patterns that employed strict symmetry and geometric transformations of lines and crystalline shapes. Kunz created these mandala-like grids with colored pencil on graph paper which she used as visual instruments for healing.
