The Herrman Map of Virginia and Maryland is a detailed, four-sheet map of the Chesapeake Bay region by Prague-born cartographer Augustine Herrman. Herrman worked as a trader in the Chesapeake Bay area and served as an ambassador for New Netherland, conducting boundary discussions with Virginia and Maryland, which convinced him of the need to map the area between the Delaware Bay and Virginia. Herrman spent ten years working on Virginia and Maryland As it is Planted and Inhabited this present Year 1670, which was published in London in 1673. The map reflects his expansive knowledge of both colonies and his experience with Dutch maritime traditions. It was the first accurate map of the Chesapeake Bay coast and it, along with the John Smith Map (1612), served as the basis for most late-seventeenth and early eighteenth-century maps of Virginia.
