Copper engraving, approximately 220 x 300 cm. Large topographic and military map of Italy in excellent condition, with the sheets still intact. The map was prepared in two separate parts. Here we present only the southern section, with the Kingdoms of Naples, Sicily, and Sardinia, as well as the islands of Malta and Gozo. This work, of primary importance for Napoleonic military cartography and produced under the direction of the French Topographical Bureau, is accompanied by an elaborate allegorical frontispiece. Twenty-four large sheets of varying sizes, most approximately 55 x 70 cm. This document is considered one of the greatest achievements of ancient cartography. First edition of the most comprehensive, extensive, and complete map of Italy during the Napoleonic era, produced at a scale of 1:256,000 by the military strategist and commander Louis-Albert-Guislain Bacler D’Albe. The maps appear innovative due to the presence of strictly technical elements: the rendering of the mountains obtained through a series of shadow plays, the precision in rendering the communication routes and departmental and cantonal borders, the location of the divisions of the French army on Italian territory with reference to the generals who led them. To realize this ambitious project it took about four years, from 1798 to 1802, with an interruption caused by the return of the Austrians to Milan in April 1799: fleeing towards Paris, Bacler d'Albe, attacked by the Austro-Russian troops, lost much of the material (later returned with the Peace of Luneville after the second Italian Campaign) and was only able to finish the publication of the work at a later time. Louis Albert Ghislain Bacler D'Albe (*Saint-Pol-sur-Ternoise 1761 - †Sèvres 1824) draftsman, cartographer, battle painter, worked in Napoleon's entourage from 1796 to 1814, becoming head of the bureau topographique in 1804. He was one of the few collaborators to be admitted to the Emperor's strategic meetings: gifted with great intuition, he was entrusted with the task of collecting and organizing the topographical documentation necessary for military campaigns. Napoleon's great esteem for him was confirmed in his will, in which he recommended that his son use Bacler D'Albe's maps for his education. He was also an engraver, author of numerous views of Savoy and of places he crossed during his military campaigns. The maps appear innovative due to the presence of strictly technical elements: the rendering of mountains achieved through a series of shadow plays, the precision in rendering communication routes and departmental and cantonal boundaries, the location of the French army divisions on Italian territory with reference to the generals who led them.
