Roman Imperial, Maximus of Spain, usurper, silver siliqua, Barcelona c. 409 AD, extremely rare

The usurption of Maximus occured in the context of the revolt of Constantine III against Honorius. By 409 AD, Honorius was forced to recognise Constantine III as his co-emperor. Gerontius, a general of Constantine III, had been in Spain to fight the forces of Didymus and Verenianus, which were loyal to Honorius. He then revolted against Constantine III and declared Maximus emperor; who Maximus was is rather unclear, he may have been one of Gerontius' sons. The revolt was initially succesful, with Constantine III being reseiged in Arles, and his son Constans killed at Vienne, but was later crushed by Honorius. Gerontius was killed by forces loyal to Honorius, but at least according to Prosper Tiro, Maximus was pardoned. A later usurper also named Maximus who came from Spain may or may not have been the same person; this less fortunate Maximus was executed by Honorius.
