Gabriel Estrada San Juan: Pipa and Gallienus: Bigamy as a Political Tool

Princess Pipa of the Marcomanni, wife or concubine of Emperor Gallienus, is a character known to us by four mentions in three late sources, namely: Aurelius Victor, the Epitome de Caesaribus and the Historia Augusta. The information they provide is scarce and difficult to interpret, despite the fact that she is a key piece in the alliance formed between these Germanic people and the Empire. It is our purpose to rebuild the historiographical tradition as far as possible. In addition, we will bring up a suggestive epigraphic document and propose a new hypothesis for this alleged marriage by recalling possible similar cases at this time mentioned in other sources.
