Jacobi discovered that homogeneous, self-gravitating masses rotating uniformly and sufficiently rapidly can have the shape of triaxial ellipsoids. These are the Jacobi ellipsoids.

One possibility is that they result simply from the galaxy's triaxial form, because a set of nested, triaxial ellipsoids with differing ellipticities will show twisted isophotes if viewed from a direction that does not lie along one of the symmetry ...
Elliptical galaxies mostly ignore this prediction, leading to the notion that their shapes are triaxial ellipsoids supported not by rotation, but by anisotropy in the velocity distribution of the stars. This is shown in Fig. 3 of Davies et al.
