Fine penmanship and the copying of manuscripts were held in honor among the Byzantines. Among the monasteries which excelled in the art of copying were the Studium, Mount Athos, the monastery of the Isle of Patmos and that of Rossano in Sicily; the tradition was continued later by the monastery of Grottaferrata near Rome. These monasteries, and others as well, were studios of religious art where the monks toiled to produce miniatures, manuscripts, paintings, and goldsmith work. The triumph of Orthodoxy over the iconoclastic heresy infused an extraordinary enthusiasm into this branch of their labors.
