Seid Moustapha, “Diatribe de lIngénieur Séid Monstapha sur létat actuel de lart militaire, du genie et des sciences a Constantinople, imprimee dans la nouvelle Typographie de Scutari fondee par le Sultan Selim II, 1803, publie d’après l’edition originale… par L. Langles”, Paris, Ferra, 1810. Complete. 8vo, pp. 52. Half title. Modern binding. 3rd edition but in reality the 2nd and the only accessible. Seid (Seyyid) Moustapha was a Turkish official who studied mathematics and had first hand information about the political, economic and military structure of the Ottoman Empire, for which he proposed reforms. The implementation of such innovations had triggered the janissaries revolution in 1807, during which the Scutari press has been burned and Said has been killed. The book is firstly printed in Scutari (Constantinople) in 1803 (the second ever Turkish printing effort) and few years later Langles, a professor of oriental languages, has added notes and republished it in Paris. In 1807 he made the first impression attempt (only one known copy, of his personal collection) and republished the book in 1810. Only 4 known copies in international institutions. Extremely rare. Not in Atabey or Blackmer.
