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.
Rubellius Plautus Gaius Rubellius Plautus (33–62 AD) was a Roman noble and a political rival of Emperor Nero. Through his mother Julia, he was a relative of the Julio-Claudian dynasty. He was the grandson of Drusus (only son of Tiberius Caesar), and the great-grandson of Tiberius and his brother Drusus. Through his great-grandmothers Vipsania Agrippina and Antonia Minor, he was also descended from Marcus Vipsanius Agrippa and Mark Antony but not from Augustus. He was descended from Augustus' sister Octavia Minor, herself a great niece of Julius Caesar.
