This book is about the tribes in the low Omo valley, they have characteristic and different uses and way of lives. Many of the photos are about the Bull Jumping ceremony in wich a young boy has to prove to his tribe that is a man. Before the ceremony all his sisters and young female relatives being whipped with sticks before the actual jumping of the bulls takes place so that the scars on her back are said to be proof of her sacrifice for the man and it is therefore impossible for the man to refuse her needs in times of emergencies. With the pictures in this book I try to show the diferences between the tribes how live in the Omo Valley.
