"Full color by Duchy or County. The first edition, first state (see our first edition, second state for comparison) of Lucas' best general atlas and the finest general atlas produced in the U.S. at that time (In asserting this we omit the Tanner and Finley American Atlases of 1823 and 1826 respectively because they were not general atlases - cartographically they may have been superior to the Lucas, but not as broad in coverage). The quality of the engraving (most of the U.S. maps were engraved by B.T. Welch, others by Young & Delker, J.V.N. Throop, Cone & Freeman, and Kneass) is superb, the detail is very fine, and the coloring is delicate and elegant. While the same Lucas drawn base maps were used in this atlas and the 1822 American Atlas by Carey and Lea (and thereby created strained relations between him and Carey and Lea), the maps in this Lucas Atlas are far superior in quality - Welch reengraved many of the maps for Lucas that Young & Delker had engraved for Carey and Lea. It is interesting to note that the Carey and Lea maps are usually earlier states of the Lucas maps. The Atlantic Islands and the West Indies Island Maps are mostly copied from Thomson's General Atlas of 1817 (see our copy) as is the Mountains and Rivers plate (reduced). Many maps are derived from the earlier Lucas Atlas of 1815-17 which copied the Oddy Atlas maps for the non U.S. state maps. Some copies have solid color. Maps of Mexico, Canada, and N. America (updated by Lucas in the arctic), are copied from Arrowsmith's General Atlas of 1823 (first ed. was 1817). The classical maps derive from Melish's Atlas of Ancient Geography of 1815.
