Answer 2

A talented writer (and protected for being in the territory of the caliph), John of Damascus initiated a vigorous defense of the sacred images in three separate publications. The oldest, called "Apologia Against Those Who Decry Holy Images," has secured its reputation. He not only attacked the emperor, but adopted a simple style that allowed the controversy to be accompanied by the simpler people, stimulating the rebellion among the faithful.
