David Léon Cahun (23 June 1841 – 30 March 1900) was a French traveler, Orientalist and writer. Life Cahun's family, who came originally from Lorraine, destined him for a military career. However, owing to family affairs he was compelled to relinquish this, and he devoted himself to geographical and historical studies. In 1863 he began to publish a series of geographical articles and accounts of his travels in Egypt and neighboring countries in the Revue Française. About the same time he published letters of travel, and a geographical review which was the first of its kind in the daily press. In 1864 Cahun set out to explore Egypt, Nubia, the western coast of the Red Sea, and Asia Minor. Returning to France in 1866, he became a political writer on the staff of La Liberté. When that paper supported the Empire, Cahun left it, joining the staff of La Réforme (1869) and La Loi. During the Franco-Prussian War he was a correspondent for several papers. On 4 September 1870, he entered the army as a volunteer, and was appointed sublieutenant of the 46th Foot the following November. When peace was established he resumed his Oriental studies, devoting himself chiefly to research concerning the Turks and the Tatars. In 1875, he was appointed to the Bibliothèque Mazarine, where he was specially engaged in the compilation of an analytical catalogue from the year 1874. Meanwhile, Cahun had begun to publish a series of historical novels dealing with ancient history, in the style of the journeys of Anacharsis in Greece. They are said by one critic to be written in temperate and pure French, combining interest with genuine archeological knowledge. It was Cahun's intention to present facts of ancient history that were not generally known, and thus make contributions to general history and geography. These novels include: Les Aventures du Capitaine Magon, on Phoenician explorations one thousand years before the common era (Paris, Hachette, 1875); La Bannière Bleue, the adventures of a Muslim, a Christian, and a pagan at the time of the Crusades and the Mongolian conquest (ib. 1876); Les Pilotes d'Ango, dealing with French history in the sixteenth century (ib. 1878); Les Mercenaires, set during the Punic Wars (ib. 1881); Les Rois de Mer, on the Norman invasions (Chasavay, 1887); Hassan le Janissaire, on Turkish military life in the sixteenth century (crowned by the French Academy); La Tueuse, scenes from the
