Maps Charts Index

Hub

Maps and charts are among the most revealing primary sources in historical research — every map carries the assumptions, knowledge limits, and intelligence priorities of the people and institutions that made it. The subdomain indexes cartographic primary sources across every era and tradition: Babylonian world maps, the Ptolemaic Geographia and its medieval transmission, the Roman Peutinger Table, Islamic Golden Age cartography (al-Idrisi, al-Khwarizmi), portolan charts of the Mediterranean trading powers, the dramatic European cartographic expansion 1450–1750 (Waldseemüller, Mercator, Hondius, Blaeu), the great naval hydrographic programmes of the seventeenth and eighteenth centuries (the British Hydrographic Office founded 1795, the French Dépôt des cartes et plans de la Marine, the Spanish Dirección de Hidrografía), nineteenth-century imperial mapping (Ordnance Survey, the Great Trigonometrical Survey of India), and twentieth-century military cartography and satellite imagery. Notes catalogue where charts survive, how to access them, what they show and don’t show, and how they relate to the events any given subdomain covers. The charts available to Trafalgar-era commanders — many decades old, hand-corrected from generations of observations — that the current vault focus examines are one slice of this much longer story.
