The plan of the cathedral has, like that of other cathedrals, been changed from century to century; but in spite of innumerable modifications, the original plan asserts itself. From the fourteenth to the seventeenth century the Church of Notre Dame was left nearly untouched. Then, however, in obedience to the wishes of Louis XIII., it was subjected to a whole series of pretended embellishments, for which "mutilations" would be a fitter word. In the eighteenth century, between the years 1773 and 1787, damaging "improvements," and "restorations" of the most destructive kind, were introduced; until at the time of the Revolution the idea was entertained of depriving the venerable edifice altogether of its religious character. The outside statues were first threatened, but Chaumette saved them by dwelling upon their supposed astronomical and mythological importance. He declared before the Council of the Commune that the astronomer Dupuis (author of "L'origine de tous les Cultes") had founded his planetary system on the figures adorning one of the lateral doors of the church. In conformity with Chaumette's representations, the Commune spared all those images to which a symbolic significance might be attached, but pulled down and condemned the statues of the French kings which ornamented the gallery and the principal façade. The cathedral at the same time lost its name. Temple of Reason it was now, until the re-establishment of public worship, to be called. Then new mutilations were constantly perpetrated, until at last, in 1845, the work of restoring the cathedral was placed in competent hands, when, thanks to the learning, the labour, and the taste of MM. Lassus and Viollet-Leduc, Notre Dame was made what it still remains--one of the most magnificent specimens of mediæval architecture to be found in Europe. Why describe the ancient monument, when it is so much simpler to represent through drawings and engravings its most characteristic features? Some of the most interesting, most curious facts of its history may, however, be appropriately related. The Count of Toulouse, Raymond VII., accused of having supported the Albigenses by his arms and of sharing their errors, was absolved in Notre Dame from the crime of heresy after he had formally done penance in his shirt, with naked arms and feet, before the altar. An attempt was made by a thief to steal from the altar of Notre Dame its candlesticks. After concealing himself in the roof, the man, aided by other members of his band, let down ropes, and, encircling the silver ornaments, drew them upwards to his hiding-place. In performing this exploit, however, he set fire to the hangings of the church, by which much damage was caused.
