'' is thought to be either Marcus or Manius, both of which were common ''praenomina'' within the Acilia ''gens''. Although some historians such as John Platts, William A'Beckett and Angelo Paredi have thought the "M" to stand for a second ''nomina'' Manlius. It is unclear whether Aurelous came to the attention of the Emperor Gallienus after enlisting in the army, or during his service as a groom. Gallienus was known to promote talent from outside the establishment, and Aureolus was one of the New Men who replaced senators in positions of high command in the army in the course of his reign.

As a former Imperial Horsemaster, Aureolus developed a self-contained cavalry force to increase the effectiveness of the

The army of the Macriani, which first supported usurper Ingenuus and then Regalianus, included inmates from garrisons in Danubian provinces and was estimated to be at least 30,000 strong.

was recovered from the Gallic Empire and Postumus's inscription on the Augsburg Altar was erased. However, Postumus managed to evade complete defeat, which some historians blame on the alleged 'carelessness' of Aureolus. Other historians have suggested that Aureolus deliberately allowed the Gallic usurper to evade destruction to see Gallienus displaced as Emperor. Zosimus reported that Aureolus and two other officers conspired against Gallienus, but that all of them were punished and submitted, except Aureolus, who retained his anger against the emperor. The reasons for this are unknown, however, it is speculated that as a Dacian Aureolus resented Gallienus for using the Dacian garrison to reinforce his field army for the defence of Italy, compounding the problems of barbarian incursions into Dacia. Despite his failure to destroy Postumus in Gaul, Aureolus was given sole responsibility for the campaign against the Macriani. However, when the

, the Roman lands north-east of the upper Rhine were lost to the Empire. From Mediolanum, Aureolus invited Postumus to challenge Gallienus for the Empire with his support. Using the Imperial mint in Mediolanum, Aureolus had coins struck bearing Postumus's image as Emperor with appeals to the faith of his former comrades of the cavalry on the reverse. Postumus ignored his invitation and Aureolus, unsupported by the Gallic usurper, was defeated by Gallienus in a battle on the river Adda east of Milan at a place known for centuries as Pontirolo (from Latin ''Pons Aureoli'' i.e. 'The Bridge of Aureolus'). He was then besieged in Mediolanum by Gallienus' military ''comitatus,'' including the cavalry which Aureolus had created.
