Byzantine Iconoclasm
Although it is now little known, having probably been destroyed in the period of Byzantine Iconoclasm,) the icon of Christ from Camuliana in Cappadocia was the most famous Greek example, certainly from the time it reached Constantinople in 574, after which it was used as a palladium in battles by Philippikos, Priscus and Heraclius, and in the Pannonian Avar Siege of Constantinople in 626, and praised by George Pisida.
