This volume collates and analyses petroglyphs from the eastern desert of Egypt. Images of wild animals, domestic animals, anthropoids and boats, together with geometric patterns, are classified and assessed by statistical means to reach conclusions about the preferences of the artists in terms of subject matter, style, context and geographical distribution. The dataset is compared with petroglyphs from the Nile Valley and further afield to establish possible connections, contacts and influences. Issues of dating and meaning are also addressed.
