Saint Emilian, Bishop of Cyzikus, lived during the reign of the Iconoclast emperor Leo the Armenian (813-820). He was summoned together with other bishops to the court of the emperor, who insistently urged the bishops to refrain from the veneration of holy icons. St Emilian was the first to tell the emperor firmly that the question of the veneration of holy icons ought to be discussed and decided only within the Church by its spiritual leaders, and not at the imperial court. In the year 815 he was sent to prison for the Orthodox Faith, where he died as a confessor.
