From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Even after the first successes he had negotiated in this spirit with Lucius Scipio; it was the revolutionary party, which had not only broken off these negotiations, but had subsequently, at the last moment before their downfall, resumed the massacres afresh and more fearfully than ever, and had in fact conspired with the inveterate foes of their country for the destruction of the city of Rome. The cup was now full. By virtue of his new official authority Sulla, immediately after assuming the regency, outlawed as enemies of their country all the civil and military officials who had taken an active part in favour of the revolution after the convention with Scipio (which according to Sulla's assertion was validly concluded), and such of the other burgesses as had in any marked manner aided its cause.
Whoever killed one of these outlaws was not only exempt from punishment like an executioner duly fulfilling his office, but also obtained for the execution a compensation of 12,000 -denarii- (480 pounds); any one on the contrary who befriended an outlaw, even the nearest relative, was liable to the severest punishment. The property of the proscribed was forfeited to the state like the spoil of an enemy; their children and grandchildren were excluded from a political career, and yet, so far as they were of senatorial rank, were bound to undertake their share of senatorial burdens.
The last enactments also applied to the estates and the descendants of those who had fallen in conflict for the revolution--penalties which went even beyond those enjoined by the earliest law in the case of such as had borne arms against their fatherland. The most terrible feature in this system of terror was the indefiniteness of the proposed categories, against which there was immediate remonstrance in the senate, and which Sulla himself sought to remedy by directing the names of the proscribed to be publicly posted up and fixing the 1st June 673 as the final term for closing the lists of proscription.
