A simple, novice-friendly scheme for classifying the image configurations of quadruply lensed quasars is proposed. With only six classes, it is intentionally coarse-grained. Readers are invited to test drive the scheme on a sample of 12 quadruply lensed quasar systems. The taxonomy is effectively 2+1 dimensional in that the angular configuration of the images couples only weakly to the non-circularity of the configuration. The scheme can be extended to systems for which the lensing galaxy is…

Robust modeling of quadruply lensed quasars (and random quartets) using Witt's hyperbola
We develop a robust method to model quadruply lensed quasars, relying heavily on the work of Witt (1996), who showed that for elliptical potentials, the four image positions, the source, and the
