Abstract. We review some work done with C. Rovelli on the use of the eigenvalues of the
Dirac operator on a curved spacetime as dynamical variables, the main
motivation coming from their invariance under the action of diffeomorphisms.
The eigenvalues constitute an infinite set of ``observables'' for general
relativity and can be taken as variables for an invariant description of the
gravitational field dynamics.
