7 Thus the lex Aelia Sentia having prescribed a certain mode of manumission for owners under twenty, it followed that though a person fourteen years of age could make a will, and therein institute an heir and leave legacies, yet he could not confer liberty on a slave until he had completed his twentieth year. But it seemed an intolerable hardship that a man who had the power of disposing freely of all his property by will should not be allowed to give his freedom to a single slave: wherefore we allow him to deal in his last will as he pleases with his slaves as with the rest of his property, and even to give them their liberty if he will. But liberty being a boon beyond price, for which very reason the power of manumission was denied by the older law to owners under twenty years of age, we have as it were selected a middle course, and permitted persons under twenty years of age to manumit their slaves by will, but not until they have completed their seventeenth and entered on their eighteenth year. For when ancient custom allowed persons of this age to plead on behalf of others, why should not their judgement be deemed sound enough to enable them to use discretion in giving freedom to their own slaves? TITLE VII. OF THE REPEAL OF THE LEX FUFIA CANINIA Moreover, by the lex Fufia Caninia a limit was placed on the number of slaves who could be manumitted by their master's testament: but this law we have thought fit to repeal, as an obstacle to freedom and to some extent invidious, for it was certainly inhuman to take away from a man on his deathbed the right of liberating the whole of his slaves, which he could have exercised at any moment during his lifetime, unless there were some other obstacle to the act of manumission. TITLE VIII. OF PERSONS INDEPENDENT OR DEPENDENT 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.
