H. A. Guerber, Myths of the Norsemen: From the Eddas and Sagas… (1909)
“ In his hand Odin generally caried the infallible spear Gungnir, which was so sacred that an oath sworn upon its point could never be broken, and on his finger or arm he wore the marvellous ring, Draupnir, the emblem of fruitfulness, precious beyond compare. When seated upon his throne or armed for the fray, to mingle in which he would often descend to earth, Odin wore his eagle helmet; but when he wandered peacefully about the earth in human guise, to see what men were doing, he generally donned a broad-brimmed hat, drawn low over his forehead to conceal the fact that he possessed but one eye. ”
