The Jumpers, or sopouny, founded by one Petroff, considered it their duty to blow upon one another during Divine Service. This arose from a misinterpretation of the ninth verse of the fortieth psalm. It was also their custom to pile benches one upon another and pray from the top of them, until some hysterical female fell to the ground in a religious paroxysm. One of those present would then lean over her and act the scene of the resurrection. Petroff was a great admirer of King David, and would sing his psalms to the accompaniment of dancing, like the psalmist before the Ark. His successor, Roudometkin, reorganised the Jumpers, and gave their performances a rhythmic basis. Foreseeing the near advent of the Saviour, he caused himself to be crowned king of the "spiritual Christians" in 1887, and married a "spiritual" wife, though without discarding his "material" one. His successors all called themselves "Kings of the spiritual Christians," but they had not the authority of poor Roudometkin, who had been removed to prison in Solovetzk.

We may class with the Jumpers the Holy Brothers, or chalapouts, who believed in the indwelling presence of the Holy Ghost. They were visionaries of a more exalted kind, and often attained to such a state of religious enthusiasm that in their longing to enter heaven they climbed to the roofs of houses and hurled themselves into space.
