"Douze ans de séjour dans la Haute-Éthiopie" by Arnauld d'Abbadie is a travel account published between 1868 and 1999. The work chronicles the adventures of brothers Arnauld and Antoine d'Abbadie in Abyssinia from 1837 to 1849. They navigated treacherous political landscapes, religious conflicts, and hostile territories while pursuing scientific goals: mapping the region, searching for the Nile's source, and supporting Christianity against Islamic expansion. Their observations captured ethnographic details, military battles, and vivid portraits of Ethiopian personalities in this largely unmapped corner of Africa.
