John Ruskin,
The Stones of Venice, Volume 2…
“ The true perfection of a painted window is to be serene, intense, brilliant, like flaming jewellery; full of easily legible and quaint subjects, and exquisitely subtle, yet simple, in its harmonies. In a word, this perfection has been consummated in the designs, never to be surpassed, if ever again to be approached by human art, of the French windows of the twelfth and thirteenth centuries. ”
