Excavation at three Late Prehistoric Eskimo sites in arctic Alaska has revealed the presence of Venetian glass trade beads in radiocarbon-dated contexts that predate Columbus's discovery of the Western Hemisphere. The bead variety, commonly known as “Early Blue” and “Ichtucknee Plain,” has been confirmed by expert examination and comparative Instrumental Neutron Activation Analysis (INAA). The beads are present in sites throughout the Caribbean, the eastern coast of Central and North America, and the eastern Great Lakes region, where they are commonly found in sites dating between approximately AD 1550 and 1750, although a diminishing presence continues into the early 1800s. Beads of this variety have not previously been reported from Alaska. Ascribed to Venetian production by their precolumbian age, the beads challenge the currently accepted chronology for the development of their production methodology, availability, and presence in the Americas. In the absence of trans-Atlantic communication, the most likely route these beads traveled from Europe to northwestern Alaska is across Eurasia and over the Bering Strait. This is the first documented instance of the presence of indubitable European materials in prehistoric sites in the Western Hemisphere as the result of overland transport across the Eurasian continent.
