Detailed map of Tartary, extending from China, Korea and Alaska in the east to Russia and the Caspian Sea in the west.
The map is centered on Tashkent. The Great Wall of China is plainly visible.
The map is from Cloppenburgh's scarce enlarged edition of Mercator's Atlas Minor.
Johannes Cloppenburg (sometimes Cloppenburgh; also H. Jan Evertsz and Johannes Everhardus) was a Dutch cartographer. Based in Amsterdam, he was active between roughly 1610 and 1644. He worked closely with the Hondius/Jansson firm and is credited with the 1630 edition of the Atlas Minor.
