This pair of maps provides a very detailed view of the Tartary region of Russia. The maps are based on Jesuit surveys, the cartography of Ivan Kyrlov, and English maps of the region. The Dutch titles appear in the bottom margins. Sizes vary slightly.

A. Carte de la Tartarie Orientale… covers the eastern part of Tartary with part of present-day Manchuria and Sakhalin Island. The map was based primarily on Jesuit and English sources and is particularly detailed with regard to the river systems. B. Carte de la Tartarie Occidentale… covers western Tartary focused on the region of present-day Mongolia. This map includes information from Kyrkov's important surveys of this remote region in addition to Jesuit and English sources. It includes detail of the roads and shows sections of the Great Wall. It is dated 1749, when it was first published in the French edition of Prevost's history of important voyages.
