According to Eiríks saga rauða (“Erik the Red’s Saga”), while returning to Greenland in about 1000, Leif Erikson was blown off course and landed on the North American continent, where he observed forests with excellent building timber and grapes, which led him to call the new region Vinland (“Land of Wine”).

Leif Erikson, Norse explorer widely held to have been the first European to reach the shores of North America.
