On the borders of Ethiopia, Kenya and Sudan, the lower Omo Valley is a lost world. Far from any city and with a cruel climate, this land remains one of the wildest in Africa. This magnificently produced, two-volume publication is a superb chronicle of the Omo Valley’s fast-vanishing and excruciatingly hard way of life, focusing on the fifteen or so ethnic groups who have lived there since time immemorial. Hans Silvester’s photographs, as beautiful as they are fascinating, are accompanied by a text that documents the culture and daily life of the Omo tribes. 2 volumes presented in a slipcase: Volume I Customs and Ceremonies; Volume II Face and Body Decoration. 304pp, UK.
