One man who served in this office was Ausonius, the poet and tutor of Gratian. Another man with this title oversaw the construction of the Theodosian Walls. That man, Anthemius, as well as Rufinus, were powerful holders of this position during the reign of Arcadius. The jurist Ulpian held this post under Alexander Severus, and the crusher of the 2nd Jewish revolt, the wonderfully named Quintus Turbo, was a longtime holder of this position under Hadrian. The transition from Afranius Burrus to Ofronius Tigellinus in this office is usually considered the turning point in the reign of Nero. The first man to usurp the throne from this position was the successor to Caracalla, Macrinus. The originally function of this position was abolished by Constantine, who created multiple posts with this name such as 'of Illyricum' and 'of the East', which was famously held by John the Cappadocian. For 10 points, name this post most famously held by Sejanus and which was originally intended to be held by the commander of the Imperial bodyguard.

{praetorian prefect} (accept {praefectus praetorio}, accept 'head/commander of the praetorian guard' I guess even though this does not apply to the first few clues)
