Proscription is No Joke

Once they reached Rome, the murders became more open and formal as the Sullan practice of proscriptions was revived. Two boards listing names were posted in the Forum - allegedly one reserved solely for senators - and those on them lost all legal protection and so could be killed by the triumvirs' men or anyone else eager to claim the reward of a share of their property. This was paid on presentation of the severed head of the victim, which was then fastened to the Rostra. The rest of the corpse was to be left where it fell or tossed into the River Tiber with the City's rubbish.
