The type conventionally designated Pax-Nemesis represents one of the more theologically sophisticated syncretisms in Roman numismatic iconography. It appears prominently on the aurei and denarii of Claudius from AD 41 under the legend PACI AVGVSTAE, yet the figure so labeled is manifestly not the conventional Pax. She advances winged, directing a caduceus downward toward a serpent at her feet, while her other hand draws out a fold of drapery at the breast. These are attributes and gestures proper to Nemesis, the divine agent of retribution and corrector of human presumption.

The imagery reproduces the apotropaic act attested for Nemesis in literary and epigraphic sources. Specifically the symbolic spitting into the bosom by which excessive good fortune was deflected and divine envy averted. Its presence on a coinage proclaiming imperial peace is therefore deliberate and programmatic. The caduceus lowered toward the serpent completes an image in which pax is constituted not as passive tranquility but as a condition actively secured through vigilance and measured retribution.
