A very nice photographic tour of the petroglyphs located in two mountain ranges in the southwest corner of Libya in north Africa, this book is filled with hundreds of color photos. Chapters cover the geography and climate of the region, dating the rock art (with discussions of relative chronology, style, technique, patina, erosion, and painting), present day impacts to the rock art, archaeology and wildlife, and the different types of engravings including cattle, buffalo, sheep, goats, man, theriomorphs and therianthrops.
