Usurper in Britain
Allectus was the chief finance minister (rationalis) to Carausius. Allectus was a very ambitious man. In 293 AD, he was the principal instigator in a plot that ended with the assassination of Carausius. Allectus was said to have been an excellent sailor and soldier. His domain included Britain and parts of Gaul. For three years he ruled supreme over his newly aquired empire. However, Carausius may have defeated Maximian and appeared to have stablized his British empire, but in fact the forces of Rome were still waiting for the right moment.
Constantius I Chlorus (father of Constantine the Great) was raised to the rank of Caesar and as such was quite eager to prove himself. Constantius set his goal as the recovery of Britain, which came within his special area of responsibility within the Tetriarchy. In 296 ad, Constantius set sail for Britain with two Roman fleets in pursuit of his enemy. Allectus reached Britain first after fleeing Gaul. He disembarked in preparation for the coming battle. Near Hampshire, the two forced clashed. Allectus’ legions were routed and shortly thereafter he was killed. The triumph greatly enhanced the status of Constantius within Rome for he had accomplished what Maximian could not.
Mints: London – Aureus, Billion Denarius, Antoninianus, Quinarius, Clausentum – Antoninianus, Quinarius
The identity of the C (sometimes CL) mint, which struck for Carausius and Allectus, is still a matter of considerable dispute. Camulodunum (Colehester) was believed to be the most likely choice. However, on the south coast there was another stronghold of importance – Clausentum (Bitterne). Clausentum was used as a base by the Channel Fleet in defense of Britain. This lends considerable weight to this alternative attribution for the “C” mint mark given the fact that mints were normally associated with military concentrations. There does remain yet a third possibility for this mysterious mint – Glevum (Gloucester). However, if this attribution were correct, then the mint mark would most likely read “G” or “OL”. The strongest candidate is this the city of Clausentum since this mint, unlike London, did not survive the defeat of the rebell state. To date, no gold coins have been discovered with this mint mark.
London mint marks are “ML” and are found on most denominations. Such mint marks thus identify coins of Carausius and Allectus as among the first British coins minted during the Roman era.
Allectus issued gold aurei, billon (debased silver)denarius, bronze antoniniani, and a smaller radiate denomination, usually termed “quinanus.” It is clear that while Carausius was first to reintroduce a silver coinage known as the denarius, it is most likely that it was valued significantly higher than the greatly depreciated antoninianus. Allectus appears to have begun the debasement of this denomination under Carausius given the fact that he was finance minister. Coinage baring his own name present yet another indication that economic conditions were far from stable in the new rebel state. The billion denarius is severely debased falling once again in silver content to less than 50%. It is also possible that the radiate “quinarius” is actually the monetary equivilent of the half-antoninianus. If the silver denarius was valued much greater than the antoninianus, then a bronze half-antoninianus would need to be issued. Therefore, this new radiate bust denomination might be more properly termed “restored bronze denarius” rather than as a “quinarius.”
