Under a natural invariance assumption on the Lévy measure we
construct compound Poisson processes and more general isotropic Lévy
processes on Riemannian manifolds by projection of a suitable horizontal
process in the bundle of orthonormal frames.We characterize such Lévy
processes through their infinitesimal generators and we show that they can be
realized as the limit of a sequence of Brownian motions which are interlaced
with jumps along geodesic segments.
