This mid-nineteenth-century historical map depicts the Roman Empire at its maximum territorial extent. Published in New York by Alvin Jewett Johnson, the map delineates ancient provinces, tribal regions, and classical geographical features spanning from the British Isles and Hispania across the Mediterranean basin to Parthia and Mesopotamia. Regions are distinctly highlighted using original pastel hand-coloring in shades of pink, green, and yellow.\n\nThe map features Johnson's trademark geometric fretwork border and includes two detailed inset maps in the upper right quadrant showing Ancient Greece (Graecia) and Ancient Italy (Italia). A key in the lower-left corner explains the administrative conventions, including capitals of the empire, kingdom seats, and historical cities.
