Wartburg, an old grim castle overhanging Eisenach (q. v.), where Luther was confined by his friends when it was too hot for him outside, and where, not forgetful of what he owed his country, he kept translating the Bible into the German vernacular, and where they still show the oaken table at which he did it, and the oaken ink-holder which he threw at the devil's head, as well as the ink-spot it left on the wall.
