Apollinaris (Latin: Apollinarius) was Praetorian Prefect of Gaul from May 408 or earlier until 409 AD,[1] when he was succeeded by his friend Decimus Rusticus.
With a mixture of fighting and diplomacy Constantine stabilised the situation and established control over Gaul and Hispania (modern Spain and Portugal) in May 408.
The sitting emperor of the Western Roman Empire, Honorius, sent an army under Sarus the Goth to expel Constantine's forces.
[4] His tenure lasted until 409, when he was ousted (possibly by Constantine III) in favor of Decimus Rusticus, who was also Master of the Offices.
Apollinaris served as the Praetorian Prefect of Gaul, a position of significant power and responsibility in the Late Roman Empire.
