J. Henry Middleton, Illuminated Manuscripts in Classical and Mediaeval Times… (1892)
“ Celtic art in Britain. In later times, when the Celtic style of illumination was transplanted to England, gold was to some extent introduced, but in the finest Irish manuscripts of the best period, the latter half of the seventh century, gold is completely absent. Nevertheless, so great was the decorative genius of these Irish monks that, even without burnished gold and silver, their illuminated pages quite equal, not only in artistic beauty, but even in mere splendour of effect, any illuminations that have ever been produced. ”
