Map "A new general map of America. Drawn from several accurate particular maps and charts, and regulated by astronomical observations. By Eman. Bowen". An impressive publication by Emanuel Bowen, "A New General Map of America" offers a distinctive perspective on the geography of North and South America during the mid-18th century, underscored by the notable absence of San Diego and San Francisco (although the latter perhaps represented by "Drakes Port"), and the inclusion of the speculative Straits of Anian. Bowen's map serves as a testament to epoch of exploration, featuring several imaginative details such as the "Parts Undiscovered" in the Northwestern part of North America and the "supposed Straits of Anian." Bowen, a prominent English mapmaker and engraver, was known for his careful amalgamation of available geographic and topographic data, making his maps valuable resources for understanding historical views of world geography. Bowen’s detailing of locations such as Cape Mendocino, New Albion, Drake's Port, Monterrey, and the Channel Islands provides insight into the geographic knowledge and misconceptions of the time. The absence of San Diego and San Francisco, cities that would later become pivotal locations in American history, highlights the evolving understanding of the continent’s western coast.
