Blue beads in the tundra
“In the 1400s, craftsmen in the city-state of Venice traded with people throughout Asia. The beads might have traveled in a horse-drawn cart along the Silk Road eastward toward China. From there, “these early Venetian beads found their way into the aboriginal hinterlands, with some moving to the Russian Far East,” the authors wrote in their recent paper.
After that great journey, a trader may have tucked the beads into his kayak on the western shore of the Bering Sea. He then dipped his paddle and made passage to the New World, today’s Alaska. The crossing of Bering Strait at its narrowest is about 52 miles of open ocean.”
