This interesting small map is reduced from Thomas Jefferys’ map of the Russian discoveries in the North Pacific, which was in turn based on Gerhard Mueller’s famous map that refuted the Delisle-Buache controversial theories of the region. It traces the voyages of Captains Bering and Tschirikow as well as earlier Russian expeditions in the Arctic. Its most recognizable feature is the enlarged peninsular form of Alaska, which would be the model for the region until Capt. Cook’s expedition.
