The Nicene Age

Who Secundianus of Singidunum was

Homoian bishop of Singidunum, deposed with Palladius of Ratiaria at Aquileia. Gratian had assured Palladius that Eastern bishops would attend and give the two of them a fair hearing; Ambrose persuaded the emperor otherwise, and the pair faced a room of thirty-two Westerners instead. Almost nothing else about Secundianus survives, which is itself the point — the losing side of a council rarely leaves a record of its own.

Also listed in bishops beyond the great sees.
