Belenus at Aquileia
Herodian's Historia, VIII.3.8-9.

There were also some oracles spread around to the effect that the local god was promising the Aquileians victory. The god, whose worship is extremely popular, is called Bele[nu]s and identified with Apollo. Some of Maximinus' soldiers said that his image appeared frequently in the sky fighting for the city. I am not sure whether the god really appeared to some of the men or whether it was their imagination. They were anxious to avoid the disgrace of being unable to resist a crowd of townsfolk that was numerically smaller, and wanted it ot appear that they had been defeated by gods and not men. The unusualness of the incident makes anything credible.
