'''== The Patriarch Nicephorus I of Constantinople =='''

Saint Nicephorus (c. 758-828), like his namesake and fellow-historian Gregoras five centuries later, sacrificed his position in the defence of Orthodox doctrine against heresy and the Orthodox conscience agains dictation from the state. His Patriarchate (806-815) was marked, and terminated, by the reaction instigated by Leo V against the restoration of religious images.
