Historical Context
The martyrs suffered during the opening years of Byzantine iconoclasm, when the emperor Leo III the Isaurian moved against the veneration of religious images. According to the historical record, between 726 and 730 Leo ordered the removal of a prominent image of Christ from the Chalke Gate, the ceremonial entrance to the imperial palace, and around 730 issued an edict forbidding the veneration of icons.
The synaxarion relates that the icon of Christ over the Chalke (Copper) Gate had hung there since the era of Constantine the Great, and that the emperor, together with the iconoclast patriarch Athanasius, commanded its removal. The reigning patriarch Germanus, who supported the icons, was deposed; the wider record likewise notes that Patriarch Germanos I resigned or was deposed following the imperial ban.
