Many of the seventy-three abbots, from Dodon, the first (living in 637), to the last, Jean-François-Paul de Gondi, Cardinal de Retz, were distinguished for their piety, for their learning, their greed, or their vices. Amongst them we find the names of Fulrad, Hilduin, Suger, Mathieu de Vendôme, the Emperor Charles the Bald, the Kings Eudes, Robert and Hugues Capet,[15] the Cardinals de Bourbon, de Lorraine, de Guise, and Mazarin. The conventual buildings were all destroyed in the reign of Louis XV., and during the Revolution the church suffered in the same way as Notre-Dame and S. Eustache, by being secularized in the most revolting manner. But if the Revolutionists destroyed and carried away monuments, the Imperial architects did worse, for they began a restoration in their own hideous taste and "style"; and it was not until a few years ago that the old church was restored to its pristine beauty. Perhaps few churches have seen more changes than the silent walls of S. Denis have witnessed. The burial place of most of the kings of France, it was also upon its High Altar that Louis le Gros deposited the _oriflamme_, the famous standard of France,[16] while some seven centuries later, its tombs were only preserved from utter ruin by the wit of Alexandre Lenoir. Even the church itself was threatened with destruction, and was only saved by an architect seriously suggesting that it should be turned into a market, the side chapels forming shops. By turns a Temple of Reason, a _dépôt_ of artillery, a theatre of acrobats, a flour warehouse, and a granary, its desecration was not consummated until the glass was removed, and the leaden covering of its roof converted into bullets. Napoleon saved what remained, and began restoring it as a resting-place for the defunct members of his dynasty. The Concordat guaranteed it a chapter, and religious services were restored.[17] But the 19th century proved as disastrous as wars and revolutions. Lightning once more brought down the _flèche_ in 1837, and again in 1846; and scrapings and cleanings carried away all the old surfaces of the walls. Still, through the talent and learning of Viollet-le-Duc, it is one of the finest of 13th century churches, and now that the tombs have all been replaced in their former positions, one of the most interesting.
