But of natural landscape there is nothing, unless rocks and trees of a stereotyped character can be so regarded. Hence the background of the miniature of the 12th and immediately succeeding centuries became the field for decoration to throw into stronger relief the figures in the scene. And thus arose the practice of filling in the entire space with a sheet of gold, often burnished: a brilliant method of ornament which we have already seen practiced in the Byzantine school. We have also to notice the conventional treatment of the sacred figures, which continue henceforward, from a sense of veneration, to be clad in the traditional robes of the early centuries, while the other figures of the scene wear the ordinary dress of the period.
