Lictor

A lictor (possibly from Latin: ligare, "to bind") was a Roman civil servant who was a bodyguard to magistrates who held imperium. Lictors were used since the Roman Kingdom, and according to Roman historian Livy, the custom may have originated earlier, in the Etruscan civilization.

According to Livy, lictors were introduced by Rome's first king, Romulus, who appointed 12 lictors to attend him. Livy refers to two competing traditions for the reason that Romulus chose that number of lictors. The first version is that 12 was the number of birds that appeared in the augury, which had portended the kingdom to Romulus. The second version, favoured by Livy, is that the number of lictors was borrowed from the Etruscan kings, who had one lictor appointed from each of their 12 states.

Originally, lictors were chosen from the plebs, but through most of Roman history, they seemed to have been freedmen. Centurions from the legions were also automatically eligible to become lictors on retirement from the army. They were, however, definitely Roman citizens, since they wore togas inside Rome. A lictor had to be a strongly built man, capable of physical work. Lictors were exempted from military service, received a fixed salary (of 600 sesterces, in the beginning of the Empire), and were organized in a corporation. Usually, they were personally chosen by the magistrate they were supposed to serve, but it is also possible that they were drawn by lots.

Lictors were associated with Comitia Curiata and, probably, one was originally selected from each curia, since there were originally 30 curiae and 30 lictors (24 for the two consuls and six for the sole praetor).
