Saint Callinicus I of Constantinople

Callinicus I of Constantinople (Greek: Καλλινίκος; died November 711) was the Ecumenical Patriarch of Constantinople from 693 to 705. Callinicus I helped to depose Emperor Justinian II and place Leontius on the Byzantine throne. Upon Justinian II's triumphant return to Constantinople and reinstatement as Emperor, Callinicus I was arrested and blinded before being imprisoned in a monastery. He is recognized as a saint by the Eastern Orthodox Church; his feast day is celebrated on 23 August.
