An image of a Hopewell textile retrieved from Ohio Seip burial mounds in southern Ohio. Photographed in simulated daylight (top left), some patterns can be seen by the unaided eye. Ultraviolet reflectance (top right) and fluorescence (bottom right) images reveal better, previously invisible views of lighter patterns near the center of the textile. Infrared (bottom left), however, exposes darker patterns in sharp contrast to lighter decorations. Such information could help archaeologists more wisely choose areas to sample ancient textiles and other artifacts. All photos by Christel Baldia and Kathryn Jakes.
