15th Century Mongolia

Early in the fifteenth century, Hans Schiltenberger was captured by the Turks and sent to the court of Tamerlane, who placed him in the retinue of a Mongol prince named Egidi. After returning to Europe in 1427, Schiltenberger wrote about his experiences. In his book, he describes some mountains, apparently the Tien Shan range in Mongolia:

"The inhabitants say that beyond the mountains is the beginning of a wasteland which lies at the edge of the earth. No one can survive there because the desert is populated by so many snakes and tigers. In the mountains themselves live wild people, who have nothing in common with other human beings. A pelt covers the entire body of these man creatures. Only the hands and face are free of hair."

"They run around in the hills like animals and eat foliage and grass and whatever else they can find. The lord of the territory made Egidi a present of a couple of forest people, a man and a woman. They had been caught in the wilderness, together with three untamed horses the size of asses and all sorts of other animals which are not found in German lands and which I cannot therefore put a name to."
