Guillelmo Delille’s “Map of the Countries Neighboring the Caspian Sea” is the first detailed map of the region between the Black Sea and the Caspian Sea.

A significant role in developing this map was played by the Georgian diplomat, traveler, and writer—Sulkhan-Saba Orbeliani.

Guillelmo Delille acknowledged Sulkhan-Saba’s significant contribution to creation of the map by personally depicting his name on the map and mentioning it in the map’s legend as Sofkam Sabas, Prince de Geoorgie (Sulkhan-Saba, Prince of Georgia). 

The map depicts all the kingdoms, principalities, and regions of Georgia, along with numerous geographical features—cities, villages, rivers, lakes, mountains, fortresses, churches and monasteries, roads, and more.
