The Vitrasii were originally an equestrian family of Campania; the earliest known member, Vitrasius Pollio, served as a Procurator of Egypt under the Emperor Tiberius.

Flamininus' cursus honorum can be reconstructed in part from an inscription found in Cales, erected by his father Lucius Vitrasius Ennius Aequus.

Ronald Syme examines this peculiar combination of provinces and a military command, and considers the possibility that Ernst Stein first raised that Flamininus held these commands simultaneously but could not provide a reason; it was another scholar, Zwikker, who suggested that the demands of the Marcomannic Wars was the reason.

Syme notes, "The notion of a single command tenuously extended all the way from Piedmont to Serbia is highly vulnerable.

Syme argues that Flamininus governed at least some of these at different times, and that his command of an exercitus or military force was to "clean up latrones in Bosnia and western Serbia, whether recalcitrants or conveniently deemed such.
