Such was the enthusiasm that produced the rich designs of rose windows like that of San Pedro in Avila, the doors of Toledo Cathedral, the marvellous architecture of Burgos Cathedral, and that of León and many other sacred buildings in the Peninsula. When surveying with delight these examples of æsthetic inspiration, we must remember that the artists worked not only to charm men, but to show reverence to their God. Every curve, tracery and adornment was conceived in a spirit of pious homage and of religious duty. It is only when faith is enfeebled that we may observe the touch of indifference in the hand of the ecclesiastical builder and artist. There is nothing 'cheap,' nothing hasty, nothing paltry in the scheme and construction of the temples dedicated by mediæval believers to the worship of God and the Holy Virgin Mother. We may have outgrown the taste in certain forms of decoration, but the work will not strike us as ill-considered and commonplace. It stands as a testimony to the influence of faith and devotion upon the imagination and the artistic spirit. If the modern churches of Spain disappoint us, we must remember that in these days men have, to a marked extent, lost that tenacity of belief, which once urged them to expend a great share of their wealth upon the founding of splendid houses of worship. 'The temples made by hands' are to-day less beautiful than those of the age when creed ranked before country, and was the absorbing subject and the profoundest conviction of the Spanish mind. But the ancient cathedrals and churches endure as solemn memorials. Atmospheric influences do not cause crumbling and speedy decay in this land of dry winds and sunshine. The edifices were built to stand, and they have stood well the wear and tear of the centuries.
