The projected density of a galaxy is shown to be simply related to the projected potential. The properties of the projections of Stäckel potentials are explored. Projected Stäckel potentials have two symmetry axes, and satisfy a simple general equation, comparable to the general equation for a Stäckel potential. Deprojection of these potentials is generally non-unique, even if one has set the axis orientation. Similar results are obtained for the projected density distributions of mass models with a Stäckel potential. One of the consequences is that these triaxial mass models show no twist when projected. Models with a Stäckel potential are a subset of an extensive class of triaxial models which project to symmetrical distributions. Implications for the interpretation of surface photometry of elliptical galaxies are discussed.
