Devil is captured and imprisoned in an old gray castle

A group of young people happen upon an old man in a castle who turns out to be the devil.

"The picture shows the Devil working at a fire. Two cavaliers appear, and the Devil takes the form of a seer, old, bent and wrinkled. Then he disappears in a cloud of smoke, to reappear shortly as a ghost, whose head comes off and floats around the room. Suddenly the table gets up of itself, and flies up the chimney. All sorts of wonderful things happen. A cannon takes the place occupied by the table, and belches forth flame and smoke. A large cage appears mysteriously in the center of the room, through the bars of which the Devil passes as if it were an open door. By his magic, he makes the cavalier pass through the bars in the same wonderful fashion. Everything is so weird and fantastic, that such a small trifle as a man turning into a donkey excites but passing notice." -Edison catalog
