You see their work, you behold the material in which they wrought, as you stand before the western façade[58] and gaze in wonder; for the stones, it seems, have become intelligent, and matter is here spiritualised. But you will almost cease to wonder when you remember the spirit in which they wrought it. Such was the spirit, and such only could be the spirit, which produced the master-art of Gothic, and led the daring architects from step to step in the attainment of their triumphs, as they left behind them the heavy piers and the thick dark arches of the Pagan Romanesque and arrived at last at the perfect expression of the Christian spirit in their soaring arches, their airy buttresses, and their pointing pinnacles flaming upwards to the skies. Seven miles distant from Chartres lie the quarries of Berchères-l’Évêque, whence, in the spirit and manner that has been described, they brought this ‘miraculous’ stone--miraculous, for it was in a vision that the existence of the quarry was said to have been revealed. Miraculous one may almost call it still, by reason of its quality of hardness, its gift of wear, and the exquisite tones which it has taken on with years. Of the two towers the old one is the better built; many of the stones of the other were laid in too little mortar and have consequently split. These blocks of stone are marked with various masonic signs, a fact which confirms the supposition that the two towers were built by the Frères Maçons or Logeurs du bon Dieu, as they were called, those famous associations of the Middle Ages, corporations of artist workmen, who were indeed ‘masters of the living stone.’ The first time that the traveller beholds the porches of Chartres he is filled with admiration for the exquisite effect of the whole, and afterwards for the exquisite details of which that whole is composed. He may, if he is of an imaginative temperament, fall into some reverie and picture to himself a host of historic fantasies.
