Cecropius of Nicomedia

Cecropius of Nicomedia was a bishop of Nicomedia and a key player in the Arian controversy.

Cecropius, a semi-Arian, had been Bishop of Laodicea, and was transferred from Laodicea by the Arian emperor Constantius I in 351AD. Athanasius bishop of Alexandria, was critical of this appointment and royal interference in the church.

As Bishop, Cecropius attended the synod of Sirmium which deposed Photinus and he attended the consecration of a new church building in Anevra, in 358.
