It’s sort of crazy to think that people are still discovering new information about our “recent” (in historical terms) past. Mills, the paper reports that Venetian blue glass “trade beads” were found at three Late Prehistoric Eskimo sites within the Arctic Circle. In finding the beads, they knew conclusively that trade routes had been established prior to Columbus because:Indigenous peoples in the Americas did not have the material glass, so the beads were considered valuable trade items. As the glass capital of Europe, many such beads were produced in Venice–known as Murano glass. A possible route of small glass beads from the city of Venice to prehistoric house sites in northern Alaska.
