London: J. Arrowsmith, 1842. Map. Engraving with original hand-coloring. Image measures 24 1/2 x 19 1/2"
This beautifully color-coded and robustly labeled map describes the geology of the British Isles. The colors indicate particular rock materials in accordance with a key at top right of the map, and symbols designate mineralogical deposits. In addition to geological information, the index also includes major cities, rivers, canals, mail coach roads, and railroads. Graphs on the left side depict lines of navigation throughout the area. This map is from Arrowsmith's "London atlas of universal geography" and is in good condition with vivid colors. Some wear and staining in margins not affecting the image. Wear to original center fold. John Arrowsmith (1790-1873) was from a family of London based cartographers and publishers, and was a founding member of the Royal Geographical Society. His "London Atlas," known for its understated elegance, is considered one of the first truly "modern" atlases of the nineteenth century. This finely colored map is a lovely example of his work.
