Note to JULIUS CAESAR, 4.1.17, 'proscription'
Here's what Wikipedia has about this proscription:
It began with an agreement in November 43 between the triumvirs Octavian Caesar, Marcus Antonius, and Marcus Lepidus after two long meetings. Their aim was to avenge Julius Caesar's assassination, eliminate political enemies, and acquire their properties. The proscription was aimed at Julius Caesar's conspirators, such as Brutus and Cassius, and other individuals who had taken part in the civil war, including wealthy people, senators, knights, and republicans such as Sextus Pompey and Cicero. There were 2,000 names on the list in total, and a handsome reward of 2,500 drachmae for bringing back the head of a free person on the list (a slave's head was worth 1,000 drachmae); the same rewards were given to anyone who gave information on where someone on the list was hiding. Anyone who tried to save people on the list was added to the list. The material belongings of the dead victims were to be confiscated. Some of the listed were stripped of their property but protected from death by their relatives in the Triumvirate (e.g., Lucius Julius Caesar and Lepidus' brother). Most, however, were killed, in some cases gruesomely. Cicero, his younger brother Quintus Tullius Cicero (one of Julius Caesar's legates) and Marcus Favonius were all killed in the proscription.Cicero's head and hands were famously cut off and fastened to the Rostra.
