Relation d’un voyage dans la Marmarique, la Cyrénaïque, et les oasis d’Audjelah et de Maradèh, accompagnée de cartes géographiques et topographiques, et de planches représentant les monuments de ces contrées
Paris, Librairie de Firmin Didot père et fils, 1827-1828
First edition of an account of the author’s exploration of Cyrenaica, accomplished between November 1824 and July 1825. On his return to France, Pacho claimed a prize of 3000 francs sponsored by the Société de Géographie in Paris for an account of that part of ancient Libya. A prospectus for the work was circulated in July 1826, projecting fourteen fascicules: four parts of text, imposed in quarto; and ten of plates, in folio, each fascicule priced on papier ordinaire 10 francs and on papier vélin with the engraved plates on papier de Chine 20 francs (“Après le Ier janvier 1827, les prix seront augmentés d’un tiers”). The first fascicules were issued in April 1827; one fascicule of text and three of plates had yet to appear when on 26th January 1829 the author committed suicide. This copy is printed on papier ordinaire, as was the only copy seen in the market in recent times. The same plates were coloured in all copies.
