The Oromo are today the most important ethnic group of Ethiopia. Until the 19th century expansion of Ethiopia most Oromo groups were living outside the Christian Ethiopian Empire. There is a general lack of older documentations of their oral traditions and literature, as this rich heritage has been started to be documented only very recently. It is the more interesting and fascinating, that a group of young Oromo living in Germany in the early 19th century have left collections of letters and accounts, in which they refer to the oral literature of their time. These texts are presented in this volume.
