  Recently, there has been a revival of interest in the Lanczos potential of
the Weyl conformal tensor. Previous work by Novello and Neto has been done with
the linearized Lanczos potential as a model of a spin-2 field, which depends on
a massless limit of the field. In this paper, we look at an action based on a
massless potential, and show that it is classically equivalent to the
linearized regime of general relativity, without reference to a massless limit.
