LXXII. Trajan to Pliny
THE QUESTION concerning children who were exposed by their parents, and afterwards preserved by others, and educated in a state of servitude, though born free, has been frequently discussed; but I do not find in the constitutions of the princes my predecessors any general regulation upon this head, extending to all the provinces. There are, indeed, some rescripts of Domitian to Avidius Nigrinus and Armenius Brocchus, which ought to be observed; but Bithynia is not comprehended in the provinces therein mentioned. I am of opinion, therefore, that the claims of those who assert their right of freedom upon this footing should be allowed; without obliging them to purchase their liberty by repaying the money advanced for their maintenance.
