According to our civil law, no one can be a citizen of two cities at the same time; a man cannot be a citizen of this city, who has dedicated himself to another city. And he may do so not only by dedication, which is a thing which we have seen happen in their misfortunes to most illustrious men, to Quintus Maximus, and Caius Laenas, and Quintus Philippus at Nuceria, and to Caius Cato at Tarraco, to Quintus Caepio and Publius Rutilius at Smyrna, who all became citizens of those cities. (They could not lose their rights of citizenship here, before they had as it were changed their country by their change of citizenship.)
But a change of citizenship can also take place by a man's returning to his original city. Nor was it without reason that a motion was submitted to the people concerning Cnaeus Publicius Menander, a freedman, whom in the time of our ancestors some ambassadors of ours when going into Greece wished to take with them as an interpreter, that that Publicius if he returned to his home, and after that again came back to Rome, should still be a Roman citizen. For, in the recollection of earlier times, many Roman citizens of their own free will, not having been condemned by any process of law, nor having been in danger, have left our state and joined themselves as citizens to other cities.
