history of the region. The Abbadie brothers not only traveled around Abyssinia, they also saw, listened to and noted a great deal; human geography joins physical geography, but also religion, legislative texts, ethnography, philology, linguistics, numismatics, history, etc. Antoine collects 250 old manuscripts, and creates with the help of the Ethiopian Debtera Tewelde Medhin de Welkait, the first Amharic-French dictionary of 15,000 words and a lexicon of 40,000 words from 30 different languages. Antoine became involved in various controversies relating both to his geographical results and his political intrigues. He was especially attacked by Charles Tilstone Beke, who impugned his veracity, especially with reference to the journey to Kana. But time and the investigations of subsequent explorers have shown that Abbadie was quite trustworthy as to his facts, though wrong in his assertion — hotly contested by Beke — that the Blue Nile was the main stream. The topographical results of his explorations were published in Paris between 1860 and 1873 in Géodésie d'Éthiopie, full of the most valuable information and illustrated by ten maps. Of the Géographie de l'Éthiopie (Paris, 1890) only one volume was published. In Un Catalogue raisonné de manuscrits éthiopiens (Paris, 1859) is a description of 234 Ethiopian manuscripts collected by Antoine. He also compiled various vocabularies, including a Dictionnaire de la langue amariñña (Paris, 1881), and prepared an edition of the Shepherd of Hermas, with the Latin version, in 1860. He published numerous papers dealing with the geography of Ethiopia, Ethiopian coins and ancient inscriptions. Under the title of Reconnaissances magnétiques he published in 1890 an account of the magnetic observations made by him in the course of several journeys to the Red Sea and the Levant. The general account of the travels of the two brothers was published by Arnaud in 1868 under the title of Douze ans dans la Haute Ethiopie. Antoine was responsible for streamlining techniques in geodesy, along with inventing a new theodolite for measuring angles. Basque and bascophile Basque through his father, Abbadie developed a particular interest in the Basque Language after meeting Prince Louis Lucien Bonaparte in London. He started his academic work on Basque in 1852. A speaker of both Souletin and Lapurdian, a resident of Lapurdi, Abbadie considered himself a Basque from Soule. The popularity of the motto Zazpiak Bat is attributed to Abbadie, coined in the framework of the Lore Jokoak Basque festivals that he fostered.
