  We use the theory of selfdual Lagrangians to give a variational approach to
the homogenization of equations in divergence form, that are driven by a
periodic family of maximal monotone vector fields. The approach has the
advantage of using $\Gamma$-convergence methods for corresponding functionals
just as in the classical case of convex potentials, as opposed to the graph
convergence methods used in the absence of potentials. A new variational
formulation for the homogenized equation is also given.
