Luther gives a long history of how he was called to a parish priest, who complained of the devil's having created a disturbance in his house by throwing the pots and pans about, and so forth, and of how he advised the priest to exorcise the fiend by invoking his own authority as a pastor of the Church.
At the Wartburg, Luther complained of having been very much troubled by the Satanic arts.

When he was at work upon his translation of the Bible, or upon his sermons, or engaged in his devotions, the devil was always making disturbances on the stairs or in the room.

One day, after a hard spell of study, he lay down to sleep in his bed, when the devil began pelting him with hazel-nuts, a sack of which had been brought to him a few hours before by an attendant.

He invoked, however, the name of Christ, and lay down again in bed.

There were other more curious and more doubtful recipes for driving away Satan and his emissaries.
