Leo V
In the course of their journey, in about 812, they landed in Constantinople, entered a monastery, and where in opposition to the Emperor Leo V (813-20) they energetically defended the veneration of images. However, the Seventh Ecumenical Council had condemned Iconoclasm as a heresy, so they were detained, interrogated, beaten and imprisoned by order of the Emperor Leo V (the Armenian) in 815. During the whole of the second iconoclast period—nearly thirty years—they suffered at various times exile, imprisonment and torture.
