The prelates and sovereigns who succeeded to these stormy days endeavoured to restore Notre-Dame; but the ignorance which prevailed at the commencement of the present century with regard to Gothic architecture rather added to the destruction than mended it; and it was not until the Christian art and Liberal Catholic revivals led by Montalembert and his friends that a thorough and rational restoration of the church was commenced by the eminent architects, Viollet-le-Duc and Lassus. The central portal is a mass of wonderful sculpture. The lower part of the stylobate bears lozenge-shapen compartments enclosing roses and lilies. Above this are the _Virtues and Vices_,[112] the former being figures of women bearing their emblems; the latter, little scenes describing each particular vice. It is interesting to see that the Virtues should be portrayed as women, Guillaume Durand giving the reason that they are men's nursing mothers; but Eve, having been supposed from all time to have been man's temptress, how comes it that the Mediæval sculptors exempted her and all other women from personifying the vice, for example, of curiosity? Courage our first mother undoubtedly had, and so this virtue on the front of Notre-Dame is represented by a woman with a shield bearing a lion. Equally certain is it that Adam was mean and cowardly, and so we find Cowardice painted as a man running away terror-stricken from a harmless hare. Amongst the vicious we see Judas in despair, an iniquitous Nero, an impious Mahomet, and a funny little Nimroud throwing a javelin at the sun, symbolic of that great warrior's attempt to build a high tower in order to attack Heaven itself. Above the Virtues and Vices are the Twelve Apostles, placed over the Virtue which in their lives they especially displayed. Nothing in these sculptures was done without a purpose; thus S. Paul stands over Courage, and S. Peter above Faith; indeed the whole doorway was designed to carry out a particular idea, and to illustrate the main doctrines of Christ, whose statue stands upon the central pier, giving the benediction to all who enter.
