[ULPIANUS libro primo disputationum. ] §1.16.1.prProconsul ubique quidem proconsularia insignia habet statim atque urbem egressus est: potestatem autem non exercet nisi in ea prouincia sola, quae ei decreta est.
[ULPIANUS, from the first book of his Discussions.] A proconsul, indeed, possesses the proconsular insignia everywhere, as soon as he has departed from the city; but he does not exercise authority except in that province alone which has been assigned to him.
