We present a current summary of a program to study the quark propagator using lattice QCD. We use the Overlap and “Asqtad ” quark actions on a number of lattice ensembles to assess systematic errors. We comment on the place of this work amongst studies of QCD Green’s functions in other formulations. A preliminary calculation of the running quark mass is presented. 1.
