Using the ivory tusk of the narwhal, Ruben recounts the history of Norse settlement in Iceland and Greenland.The stone base depicts the stylized images of walrus, falcon, and polar bear banded together by an intricate overlay of Norse design elements. Following the natural spiral motion of the tusk, carved figures illustrate men carrying swords; their wives holding agricultural tools; a woman working in the field; a blacksmith at his forge; and figures harvesting the animals of land and sea. The top portion of the tusk envisions a time of contact, trade, and collaborative hunting between Norse settlers and the Thule people, ancestors of Inuit.
