[ULPIANUS libro secundo de censibus. ] §1.9.12.prNuptae prius consulari uiro impetrare solent a principe, quamuis perraro, ut nuptae iterum minoris dignitatis uiro nihilominus in consulari maneant dignitate: ut scio Antoninum Augustum Iuliae Mamaeae consobrinae suae indulsisse. §1.9.12.1Senatores autem accipiendum est eos, qui a patriciis et consulibus usque ad omnes illustres uiros descendunt, quia et hi soli in senatu sententiam dicere possunt.
[ULPIAN, On the Census, book 2]\n\n Women previously married to a consular man are accustomed to obtain from the emperor, although very rarely, that, having married again to a man of lesser rank, they may nevertheless remain in the consular dignity; as I know Antoninus Augustus to have granted this to Julia Mamaea, his cousin.\n\n Moreover, we must understand as "senators" those who descend from patricians and consuls down to all "illustrious" men, because these alone can also express their opinion in the senate.
