The Nicene Age

Who Theognis of Nicaea was

Bishop of the council's own city and one of Arius's first episcopal patrons — who signed the creed at Nicaea under imperial pressure but balked at the anathemas, was exiled with Eusebius of Nicomedia three months later, and returned by recantation to spend the next decades unpicking what he had signed. The council's host see, on the losing side of its own council.

Also listed in bishops beyond the great sees and heretics & schismatics.
