Historical Cartography of the Bosphorus Strait and Constantinople

This rare early 19th-century engraved chart presents a strategic nautical rendering of the Thracian Bosphorus, linking the Propontis, or Sea of Marmara, directly to the western shores of the Black Sea. The antique document highlights the historic walled perimeter of Constantinople along the Golden Horn, outlining early defensive batteries, coastal villages, and maritime navigation channels separating the European and Asian continents.

Early Geological Mapping of Volcanic and Schistose Soil Formations

Distinct from standard regional topography, this vintage scientific layout features unique early geological survey annotations across the surrounding Turkish landscape. The hand-drawn map distinguishes areas of “Volcanic Soil” from “Schistose Soil” deposits along the winding waterway, providing an essential historical record of early natural science documentation and environmental observation in the Ottoman Empire.
