Fine, original, steel-engraved plan of Toulon, with fine panorama of the town and port at the bottom, by the Society for the Diffusion of Useful Knowledge (SDUK). Very attractive map. The SDUK began its map publishing project under the leadership of Captain Francis Beaufort R.N. in 1829, and published the maps in parts, haltingly, over the next 15 years, completing the series in 1844, finally permitting the publication of a whole atlas. Many of the maps were actually drawn by Beaufort, who at the time was the Hydrographer to the Royal Navy, and all were closely supervised by him. J. & C. Walker worked closely with Beaufort in engraving the maps. The idea for the town plans, of which the SDUK published many dozens, was that of W. B. Clarke, an architect, who became an enthusiastic advocate for the plans, and who executed most of them himself, often on the basis of personal on-site observations. The plans are highly decorative, and often have accompanying vignettes, inset maps, and sketches of the main buildings. Finely engraved, carefully researched, the maps set a standard of excellence for commercial map-makers in England for decades to come. Dimensions 13 1/4" x 16 1/4" overall. Minor edgewear, otherwise excellent.
