The (m+n)-dimensional Einstein theory of gravitation is identified with an m-dimensional generally invariant gauge theory of DiffN, where N is an n-dimensional manifold. This means that the four-dimensional Einstein gravity can be identified as a lower dimensional gauge theory of an infinite dimensional group of diffeomorphism. We discuss the physical implications of the results.
