Carte de l'Empire de Russie. (2 maps)

Detailed map of Russia in two sheets, published at the outbreak of the French Revolution. Taken from the Atlas Géographique, published by Jean-Claude Dezauche (active 1770-1824), as successors to De l'Isle & Buache.
Engraved by the master engraver Pierre François Tardieu (1752-1798) and L.Aubert for the text.
The map is colored according a color key in the lower left corner. The yellow line indicates the joined area of Georgia, in between the Black Sea and Caspian Sea. Highly detailed , including the cities of Astrakhan, Moscow, Irkutsk, Tobolsk. In the most eastern part Alaska indicated as "Amérique Septentrionale". The "Aleutian Islands" are still Russian territory. Because of the location of the islands, stretching like a broken bridge from Asia to America, many anthropologists believe they were a route of the first human occupants of the Americas. The earliest known evidence of human occupation in the Americas is much farther south, the early human sites in Alaska have probably been submerged by rising waters during the current interglacial period. People living in the Aleutian Islands developed fine skills in hunting, fishing, and basketry. Hunters made their weapons and watercraft. The baskets are noted for being finely woven with carefully shredded stalks of beach rye.
Explorers, traders and missionaries arrived from Russia beginning in 1741.
According to the title the depiction of the Pacific is after maps by Jean François de Galaup, comte de La Pérouse (23 August 1741-1788?).
To the utmost right the island Owhyhée (Hawaii.)
