Lucius Cornelius Sulla published two lists containing 520 names on the forum in November 82 BC. The first list held 80 names, while a second list added another 440 names over the following days.
Sulla personally composed both lists which contained 520 names of senators and equites who had opposed him during the civil war. Only 75 of those 520 names survive in modern historical records today.
The four consuls for 82 BC stood at the top of that initial list with Gnaeus Papirius Carbo leading the group followed by Marius the Younger, Gaius Norbanus, and Lucius Cornelius Scipio Asiagenus.
A reward of 48,000 sesterces waited for anyone bringing a severed head from the lists and slaves received freedom if they killed their own masters listed as enemies.

Julius Caesar took control of Rome in 49 BC and asked Mark Antony to pass the lex Antonia de proscriptorum liberis which restored political rights including eligibility for magistracies to the children of victims.
