Where was the Emperor born, under whom Rufrius Crispinus was commander of the Praetorian Guard ?
Rufrius Crispinus Rufrius Crispinus was an equestrian who lived during the later Julio-Claudian dynasty. The satirist Juvenal spitefully described him as one the "dregs" of the "Nile", indicating his Egyptian origin. It is believed he came to Rome as a fish merchant. Under the Roman Emperor Claudius he was the commander of the Praetorian Guard. In 47, he suppressed a rebellion and was promoted by the Senate to the rank of praetor and was given one and half a million sesterces.
Silvanus (praetorian prefect) Silvanus (as Zosimus names him ) or Albanus (according to Zonaras ) was a Roman soldier and probably praetorian prefect during the third century ce who came briefly to the notice of history in the reign of Valerian and his co-Emperor Gallienus. He is generally assumed to have been the commander of the praetorians under Gallienus.
