Silbannacus

Mar. Silbannacus is a person from whom one assumes that they occurred at the beginning of the reign of Valerian ( 253-260 ) as a usurper to the office of Roman Emperor.

Silbannacus is only two coins known, a Antoninianus in the British Museum, which was allegedly found in Lorraine, and another from the environs of Paris, which was coined in September 253, shortly after the death of Aemilianus in Rome. Silbannacus there should therefore have briefly ruled during the march on Rome Valerian.

According to another view, the elevation of the Silbannacus is localized due to stylistic and onomastic considerations in Gallic space and in the reign of Philip the Arab ( 244-249 ) dates. Felix Hartmann brings the usurpation speculative with one of Eutropius (9.4 ) mentioned bellum civile in Gaul in conjunction. Accordingly Silbannacus to have commanded in the province of Germania superior and auxiliary forces have been defeated by Philip's successor Decius.
