A fine example of Thomas Cowperthwait and S. A. Mitchell's 1854 map of South America. The whole is engraved and colored in Mitchell's distinctive style with green border work and vivid pastels. Political and topographical features are noted and color coded with elevation rendered by hachure. The map depicts the whole of South America inclusive of Panama and the Falkland Islands. Ecuador is depicted extending well into central South America along the Amazon River – territory that is now claimed by Brazil. Peruvian and Chilean claims to a small stretch of coastline formerly claimed by Bolivia are noted. Colombia is identified under its former name, New Grenada.
This map was prepared by S. A. Mitchell for publication by the Philadelphia firm of Thomas Cowperthwait & Co. as plate no. 40 in the 1854 edition of Mitchell's New General Atlas. Dated and copyrighted, 'Entered according to act of Congress in the year 1850 by Thomas Cowperthwait & Co. in the Clerk's office of the Eastern District of Pennsylvania.'
Samuel Augustus Mitchell (March 20, 1792 - December 20, 1868) began his map publishing career in the early 1830s. Having worked as a school teacher, Mitchell was frustrated with the low quality and inaccuracy of school texts of the period. His first maps were an attempt to rectify this problem. In the next 20 years Mitchell would become the most prominent American map publisher of the mid-19th century. Mitchell worked with prominent engravers J. H. Young, H. S. Tanner, and H. N. Burroughs before attaining the full copyright on his maps in 1847. In 1849 Mitchell either partnered with or sold his plates to Thomas, Cowperthwait and Company who continued to publish the Mitchell's Universal Atlas. By about 1856 most of the Mitchell plates and copyrights were acquired by Charles Desilver who continued to publish the maps, many with modified borders and color schemes, until Mitchell's son, Samuel Augustus Mitchell Junior, entered the picture. In 1859, S.A. Mitchell Jr. purchased most of the plates back from Desilver and introduced his own floral motif border. From 1860 on, he published his own editions of the New General Atlas. The younger Mitchell became as prominent as his father, publishing maps and atlases until 1887, when most of the copyrights were again sold and the Mitchell firm closed its doors for the final time.
