...impediments to nuptials between them. Likewise, affinities, as here, and in the Digest, title "On those who are adopted." But why this, when there is no agnatio kinship through the male line between them? Reference to the Digest on the causes of divorce. But that is in the law of succeeding and in guardianship or inheritance. Here, however, it is from the law of blood, which can be removed by no civil law, as in the Digest, "On the meaning of words," the law "The rights of blood." And there is a prohibition of marriage. Why, and by another reason, is marriage impeded between them? Because they are of their own right original: "sui iuris". As above, section "On those who are of their own right," and the Code, "On incestuous nuptials," the law "On slave women."

For these are not understood to have a father, since their father is uncertain. Whence they are accustomed to be called spurii, either from the Greek word spandon, or as children without a father. It follows, therefore, that with such a union dissolved, there is no place for the exaction of a dowry. Those who contract prohibited nuptials suffer other penalties which are contained in the sacred constitutions. Sometimes, however, it happens that children who, as soon as they are born, are not in the power of their parents, are afterward reduced into the power of the father...
