Philip the Arab
We have no evidence for his career during the brief reigns of the next two emperors, Philip the Arab and Decius. Restitutianus appears again as "Praefectus Aegyptus", or governor of Roman Egypt, which post he held from 251 until his abrupt death. According to Guido Bastianini, his assistant Lissenius Proculus governed Egypt until a replacement could arrive from Rome.
