[ULPIANUS libro quinto decimo ad edictum. ] §1.17.1.prPraefectus Aegypti non prius deponit praefecturam et imperium, quod ad similitudinem proconsulis lege sub Augusto ei datum est, quam Alexandriam ingressus sit successor eius, licet in prouinciam uenerit: et ita mandatis eius continetur.
[ULPIANUS, from the fifteenth book On the Edict.] The prefect of Egypt does not lay down his prefecture and imperium, which was given to him by a law under Augustus in likeness to a proconsul, until his successor has entered Alexandria, even though the successor has arrived in the province; and it is so contained in his instructions.
