However, these edifices of the transition from the Romanesque to the Gothic, are no less precious for study than the pure types. They express a shade of the art which would be lost without them. It is the graft of the pointed upon the round arch.
Notre-Dame de Paris is, in particular, a curious specimen of this variety. Each face, each stone of the venerable monument, is a page not only of the history of the country, but of the history of science and art as well. Thus, in order to indicate here only the principal details, while the little Red Door almost attains to the limits of the Gothic delicacy of the fifteenth century, the pillars of the nave, by their size and weight, go back to the Carlovingian Abbey of Saint-Germain des Prés. One would suppose that six centuries separated these pillars from that door. There is no one, not even the hermetics, who does not find in the symbols of the grand portal a satisfactory compendium of their science, of which the Church of Saint-Jacques de la Boucherie was so complete a hieroglyph. Thus, the Roman abbey, the philosophers' church, the Gothic art, Saxon art, the heavy, round pillar, which recalls Gregory VII., the hermetic symbolism, with which Nicolas Flamel played the prelude to Luther, papal unity, schism, Saint-Germain des Prés, Saint-Jacques de la Boucherie,—all are mingled, combined, amalgamated in Notre-Dame. This central mother church is, among the ancient churches of Paris, a sort of chimera; it has the head of one, the limbs of another, the haunches of another, something of all.
