Hammer is a tribe which occupies the large territory of South Omo. They speak a language which belongs to the Omotic group of languages and display an elaborate and unique style of body decorations and clothes. Women wear leather skirts decorated with cowri shells. Their braided hair is painted with ochre, and their arms are decorated with 15 or more copper bracelets. The most important event in the Hamer society is the Bull Jumping Ceremony, the rite which marks a passage of men from one age group to another. This ceremony can be attended by tourists visiting the Hamer territory. Two principal settlements of Hamer are Dimeka and Turmi, especially colorful and interesting to visit on the market days.
