Another division of the law relating to persons classifies them as either independent or dependent. Those again who are dependent are in the power either of parents or of masters. Let us first then consider those who are dependent, for by learning who these are we shall at the same time learn who are independent. And first let us look at those who are in the power of masters.

1 Now slaves are in the power of masters, a power recognised by the law of all nations, for all nations present the spectacle of masters invested with power of life and death over slaves; and to whatever is acquired through a slave his owner is entitled.

2 But in the present day no one under our sway is permitted to indulge in excessive harshness towards his slaves, without some reason recognised by law; for, by a constitution of the Emperor Antoninus Pius, a man is made as liable to punishment for killing his own slave as for killing the slave of another person; and extreme severity on the part of masters is checked by another constitution whereby the same Emperor, in answer to inquiries from presidents of provinces concerning slaves who take refuge at churches or statues of the Emperor, commanded that on proof of intolerable cruelty a master should be compelled to sell his slaves on fair terms, so as to receive their value. And both of these are reasonable enactments, for the public interest requires that no one should make an evil use of his own property. The terms of the rescript of Antoninus to Aelius Marcianus are as follow:—'The powers of masters over their slaves ought to continue undiminished, nor ought any man to be deprived of his lawful rights; but it is the master's own interest that relief justly sought against cruelty, insufficient sustenance, or intolerable wrong, should not be denied. I enjoin you then to look into the complaints of the slaves of Iulius Sabinus, who have fled for protection to the statue of the Emperor, and if you find them treated with undue harshness or other ignominious wrong, order them to be sold, so that they may not again fall under the power of their master; and the latter will find that if he attempts to evade this my enactment, I shall visit his offence with severe punishment.'
