Abstract
The light-cone lattice approach to the massive Thirring model is refor mulated using a local and integrable lattice hamiltonian written in te rms of discrete Fermi fields. Several subtle points concerning boundar y conditions, normal ordering, continuum limit, finite renormalization s and decoupling of fermion doublers are elucidated. The relations con necting the six-vertex anisotropy and the various coupling constants o f the continuum are analyzed in detail.
