  Recently, Corvaja and Zannier obtained an extension of the Subspace Theorem
with arbitrary homogeneous polynomials of arbitrary degreee instead of linear
forms. Their result states that the set of solutions in P^n(K) (K number field)
of the inequality being considered is not Zariski dense. In our paper we prove
by a different method a generalization of their result, in which the solutions
are taken from an arbitrary projective variety X instead of P^n. Further, we
give a quantitative version which states in a precise form that the solutions
with large height lie ina finite number of proper subvarieties of X, with
explicit upper bounds for the number and for the degrees of these subvarieties.
