In many villages there was reserved a place in a cellar, called “Padpolniki” for a chance strannik, or wanderer. A strannik must agonize himself even during sleep. Hence he would not rest in a lighted and airy room, or in a bed. Among the wanderers one sometimes met men of great intelligence who, seized by a religious mania, or plagued by an accusing conscience, would abandon their palatial homes, don rags for clothes, wrap their feet in straw, and wander, praying and crossing themselves as they trudged along.
