15. For by those censors the freed-men were enrolled in the four city tribes, excepting such as had a son more than five years old, who was their own offspring; [2] all these the censors ordered to be surveyed in the tribe wherein they had been surveyed within the last five years; and such as had a farm, or farms, in the country, exceeding in value thirty thousand sesterces,¹ were allowed the privilege of being included in the country tribes. [3] Though this reservation was made in their favour, yet Claudius still insisted, that “a censor could not, without an order of the people, take away from any man, and much less from a whole class of men, the right of suffrage. [4] For though he can remove a man from his tribe, which is nothing more than ordering him to change it, yet he cannot, therefore, remove him out of all the thirty-five tribes; which would be to strip him of the rights of a citizen, and of liberty; not to fix where he should be surveyed, but to exclude him from the survey.” [5] These points were discussed by the censors, who at last came to this compromise: [6] that out of the four city tribes, they should openly, in the court of the temple of Liberty, select one by lot, in which they should include all those who had ever been in servitude. [7] The lot fell on the Aesquiline tribe; on which Tiberius Gracchus published an order, that all sons of freed-men should be surveyed in that tribe. This proceeding gained the censors great honour with the senate, who gave thanks to Sempronius for his perseverance in so good a design, and also to Claudius for not obstructing it. [8] Greater numbers were expelled from the senate, and ordered to sell their horses, by them than by their predecessors. They both concurred in removing from their tribes and disfranchising the same persons, in every instance; nor did one of them remove any mark of disgrace inflicted by the other. [9] They petitioned that, according to custom, the year and half's time allowed for enforcing the repairs of buildings, and for approving the execution of works contracted for, should be prolonged; but Cneius Tremellius, a tribune, protested against it, because he had not been chosen into the senate. [10] This year Caius Cicereius dedicated a temple to Juno Monita on the Alban mount, five years after he had vowed it; and Lucius Postumius Albinus was inaugurated flamen of Mars.
