General relativity is derived from an action which is quadratic in the covariant derivative of certain spinor 1-form gravitational potentials. Either a pair of two-component spinor 1-forms or a single Dirac spinor 1-form can be employed. The metric is a quadratic function of these spinor 1-forms. In the two-component spinor formulation the action differs from the usual chiral action for general relativity by a total differential. In the Dirac spinor formulation the action is the real part of the former one. The Hamiltonian is related to the ones in positive energy proofs and spinorial quasilocal mass constructions.
