Cyriacus (2)

Cyriacus patriarch of Constantinople at the end of the 6th century, and successor of John Jejunator after 595, took, like his predecessor, the title of ἐπίσκοπος οἰκουμενικός, which he caused to be confirmed by a council. The Romish bishop, Gregory the Great, opposed him at first without success, but by giving his support to the usurper Phocas he finally gained his end, and Cyriacus had to renounce his title. He is said to have died of grief in 606. —Herzog, Real-Encyklopadie, 3, 221.
