This paper contains a new criterion for mappings of Riemannian manifolds to be harmonic and (as a consequence) new proofs of earlier results on harmonic mappings of closed compact Riemann surfaces. It also contains a theorem that establishes necessary and sufficient conditions that a homomorphism of Riemannian fibrations should be harmonic, in terms of mappings of the fibers and a quotient mapping of the bases of the fibrations. Bibliography: 11 titles.
