[MARCIANUS, in the second book of his Institutes.] He who holds any office in a province is also forbidden to consent to his son marrying.
In libro secundo de adulteriis PAPINIANI MARCIANUS notat: Diuus Marcus et Lucius imperatores Flauiae Tertullae per mensorem libertum ita rescripserunt: 'Mouemur et temporis diuturnitate, quo ignara iuris in matrimonio auunculi tui fuisti, et quod ab auia tua collocata es, et numero liberorum uestrorum: idcircoque cum haec omnia in unum concurrunt, confirmamus statum liberorum uestrorum in eo matrimonio quaesitorum, quod ante annos quadraginta contractum est, perinde atque si legitime concepti fuissent'.
In his note on the second book of Papinian's On Adulteries, Marcianus remarks: The deified emperors Marcus and Lucius replied by rescript to Flavia Tertulla through their freedman Mensor as follows: 'We are moved both by the length of time during which you, in ignorance of the law, were in marriage with your maternal uncle, and by the fact that you were given in marriage by your grandmother, and by the number of your children; and therefore, since all these circumstances concur in one, we confirm the status of your children born of that marriage which was contracted forty years ago, just as if they had been lawfully conceived.'
