Hugh Arnold,
Stained Glass of the Middle Ages in England and France
“ Stained glass is not one of the arts in which the method of production reveals itself at the first glance. Indeed, so few people when looking at a stained-glass window, whether a gorgeous and solemn one of the thirteenth or fifteenth century, or a crude and vulgar one of the nineteenth, realize the long and laborious process by which the result, good or bad, has been obtained, that a short description of that process as finally perfected some five hundred years ago may not be out of place here. ”
