“Hand Drawn Portolan of the Caspian Sea of 1519” by Vesconte Maggiolo: A Source of Historical Geography for the Caspian Region
Abstract
Research objectives: To conduct a detailed comparative analysis of the toponymic source known as “Hand Drawn Portolan of the Caspian Sea (1519)” by Vesconte Maggiolo, and ascertain the range and chronology of its sources. Research materials: At the turn of the fifteenth and sixteenth centuries, there were a few navigational maps – portolan charts – created in Italy which contained rather precise outlines of the coastline of the Caspian Sea. The present Portolan excels all earlier items in terms of precision of the depicted topographical realities of the region. The quality of the map we are examining was surpassed only in the seventeenth century after Peter I’s hydrographic expeditions. The high level of shoreline’s precision also strongly suggests that the map was based on authentic topographic input. Maggiolo’s map contains 136 geographical names. Results and novelty of the research: For the first time ever in domestic scholarship, we conducted a comparative historical analysis of the hand drawn portolan chart of the Caspian Sea. We also proved the correlation of some toponyms of the West Caspian region with the Timurid and local sources that covered the military campaigns of Amir Timur in the region. In our view, the “Hand Drawn Portolan Chart of the Caspian Sea (1519)” created by Vesconte Maggiolo is one of the most notable among similar works. It finds many common features with the portolan from the island of Lesina, but also contains some common elements with the Mallorca cartographic school and Fra Mauro, Egerton MS 73, and Egerton MS 2083. This research allows us to extend and systematize our understanding of Italian cartography in relation to the Caspian region. It also details or adds some facts about the presence of Europeans in this region during the Golden Horde era. Based on this topographic and toponymic analysis, we furthermore come to a conclusion that the portolan in question is derived from a protograph created in the first half of fifteenth century, reflecting the realities of the turn of the fourteenth and fifteenth centuries.
