140 step in advance was a call for the expatriation of more Roman citizens and a fresh draft on the blood of the failing Latin race. We may infer, I think, that a strong sentiment in favour of the relaxation of the Patria Potestas had become fixed by the time that the pacification of the world commenced on the establishment of the Empire. The first serious blows at the ancient institution are attributed to the earlier Cæsars, and some isolated interferences of Trajan and Hadrian seem to have prepared the ground for a series of express enactments which, though we cannot always determine their dates, we know to have limited the father's powers on the one hand, and on the other to have multiplied facilities for their voluntary surrender. The older mode of getting rid of the Potestas, by effecting a triple sale of the son's person, is evidence, I may remark, of a very early feeling against the unnecessary prolongation of the powers. The rule which declared that the son should be free after having been three times sold by his father seems to have been originally meant to entail penal consequences on a practice which revolted even the imperfect morality of the primitive Roman. But even before the publication of the Twelve Tables it had been turned, by the ingenuity of the jurisconsults, into an expedient for destroying the parental authority wherever the father desired that it should cease.
