" That settled, the number of chapels, doors, bell towers, and pinnacles are modified to infinity, according to the fancy of the century, the people, and art. The service of religion once assured and provided for, architecture does what she pleases. Statues, stained glass, rose windows, arabesques, denticulations, capitals, bas-reliefs,—she combines all these imaginings according to the arrangement which best suits her. Hence, the prodigious exterior variety of these edifices, at whose foundation dwells so much order and unity. The trunk of a tree is immovable; the foliage is capricious. "
