A map of Persia, modern Iran and surrounds, engraved by the Walkers for the Society for the Diffusion of Useful Knowledge (SDUK). The map is very detailed, providing, in addition to the expected towns, villages, and regional titles, details of topography, paths of caravans and trade routes, distances in days by loaded camel, notes on Persian history and culture, locations of water sources, springs, and wells, and comments about various tribes and peoples. In the bottom left corner, covering the Arabian peninsula is a large glossary of Persian, Arabic, and Turkish words.
The Society for the Diffusion of Useful Knowledge (SDUK), founded in 1826 lasting only until 1848, was a Whiggish London organisation that published inexpensive texts intended to adapt scientific and similarly high-minded material for the rapidly expanding reading public. The Society's main purpose was to encourage universal literacy by publishing numbers of books of good quality that would be affordable to all. It was established mainly at the instigation of Lord Brougham with the object of publishing information to people who were unable to obtain formal teaching, or who preferred self-education.
John Walker (fl. 1813-1873) and Charles Walker (1799-1872) were British cartographers, geographers, and map engravers, and the sons of the engraver and Admiralty hydrographer, John Walker (fl. 1783-1831). John, the better known of the two sons, was a founding member of the Royal Geographic Society. A third brother, Thomas (fl. 1805-1865), succeeded his father as a hydrographer to the Admiralty.
