The authors investigate the origins of the earliest script of the Cherokees, using inscriptions in the Red Bird River Shelter. Their analysis suggests that the engravings in the cave show the experimental creation of a syllabary (alphabet of signs). This in turn offers support for the historical notion that this writing system was not an ancestral practice preserved through missionaries, but an invention of the early nineteenth century; one that should be credited to the Native American pioneer scholar, Sequoyah.
