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.
Domitius Alexander Lucius Domitius Alexander (died ca. 311), probably born in Phrygia, was vicarius of Africa when Emperor Maxentius ordered him to send his son as hostage to Rome. Alexander refused and proclaimed himself emperor in 308.
