"Essai Sur L'Architecture Militaire Au Moyen Age" by M. Viollet Le Duc. Rare work printed 1854 in Paris, France. Presumed to be the first edition or a very early edition. 1854 listed as the sole date of publication. Many excellent illustrations within. Quarter bound in leather. Features bright marbled orange and papers. Very unusual for this time period. Top edge starting and light general wear. Otherwise binding sound and condition very good. Would be highly valued by the right collector for its military illustrations. Castles, trenches, cannons, etc. Questions welcome.
