Richard D KortumRichard D. Kortum is Professor Emeritus of Philosophy and Humanities at East Tennessee State University. The former Fulbright Scholar obtained his doctorate and taught at Oxford University. Soon after coming to Mongolia in 2001, his interest in prehitoric artforms led to discovery and documentation of previously unknown rock art sites; in 2008 he accomplished the sole survey of southern Bayan Ulgii aimag. His many publications include Ceremony in Stone (Nepko 2018). Kortum has introduced systematic and analytic procedures for recording rock art and is currently working on a novel means of scientifically dating Altai petroglyphs that shows great promise. Kortum, with Fitzhugh, was awarded a National Endowment for the Humanities Three-Year Collaborative Research Grant to conduct the research described in this book. Read More Read Less
