From the Historia Augusta (Attributed to Julius Capotilinus)
“Indeed, Lucius Ceionius Aelius Commodus Verus Antoninus, who was called Aelius at Hadrian’s bidding, and also Verus and Antoninus thanks to his relationship to Antoninus, does not sit among the good or the bad emperors. It is agreed that though he was not clothed in vices, he also didn’t abound in virtues; and, in addition, he did not rule freely on his own, but shared power evenly with Marcus—a man from whom he differed in the baseness of his morals and the extreme looseness of his life. For, he was a man of rather simple character who couldn’t hide anything.”
Igitur Lucius Ceionius Aelius Commodus Verus Antoninus, qui ex Hadriani voluntate Aelius appellatus est, ex Antonini coniunctione Verus et Antoninus, neque inter bonos neque intermalos principes ponitur. 4 Quem constat non inhorruisse vitiis, non abundasse virtutibus, vixisse deinde non in suo libero principatu, sed sub Marco in simili ac paris maiestatis imperio, a cuius secta lascivia morum et vitae licentioris nimietate dissensit. 5 Erat enim morum simplicum et qui adumbrare nihil posset.
