Titus Flavius Longinus Quintus Marcius Turbo was a Roman senator who held a series of offices in the emperor's service.
[2] Nevertheless, Longinus remained a member of the equestrian order until he was adlected into the Senate.
[4] This was followed by a term governing the imperial province of Gallia Lugdunensis, which Alföldy dates from around 146 to around the year 149.
The first was curator operum locumque publicorum et aedium sacrarum, which Alföldy dates to around 151.
[7] Details for Longinus' life after he stepped down from administering Moesia Inferior have not yet been recovered.
