Unknown Ethiopia attracted his attention, and he engaged with his brother Arnould in archaeological researches. Archæology proved unfruitful, and the two brothers took up geodesy. For eleven years Antoine d'Abbadie traveled though Ethiopia, living the life of the natives, and making himself master of the five Abyssinian dialects. The exploration was difficult and sown with dangers. Antoine d'Abbadie covered the country from Massouah, on the shore of the Red Sea, to the interior of the land of Kaffa, which he was the first to visit, with a triangulation that involved the fixing of five thousand positions at five hundred and twenty-five successive stations. The distance between Massouah and Mount Wocho in southern Kaffa is

With his noble character he made himself esteemed and loved during his whole
