Criteria for a simpler approach to constructing a model for the quark distribution amplitude are formulated. We describe how such a simpler (or "haplousterotic") model for the quark distribution amplitude of the nucleon is obtained from the QCD sum-rule moments of COZ.6 p., 4 figs, 12 EPS files, LaTeX, uses sprocl.sty (included) and psfig.sty, talk given at the workshop on "Virtual Compton Scattering" Clermont-Fd., Jun '96, to appear in the proceedingsHigh Energy Physics - Phenomenologytext
