Polar lands imagined on top of the strait of Bering

The painting shows the polar lands imagined above the strait of Bering. It reads: "In the northern parts there are the islands of Bargu that the Venetian Marco Polo states are looking north so much that the pole star is seen to go down towards the south" and "The Ocean, entering these islands with 19 accesses, creates four channels flowing north without interruption and here it gets absorbed by the bowels of the earth."
