But the Crusades arrive. They are a great popular movement, and every great popular movement, whatever may be its cause and object, always sets free the spirit of liberty from its final precipitate. New things spring into life every day. Here opens the stormy period of the Jacqueries, Pragueries, and Leagues. Authority wavers, unity is divided. Feudalism demands to share with theocracy, while awaiting the inevitable arrival of the people, who will assume the part of the lion: ~Quia nominor leo~. Seignory pierces through sacerdotalism; the commonality, through seignory. The face of Europe is changed. Well! the face of architecture is changed also. Like civilization, it has turned a page, and the new spirit of the time finds her ready to write at its dictation. It returns from the crusades with the pointed arch, like the nations with liberty.
Then, while Rome is undergoing gradual dismemberment, Romanesque architecture dies. The hieroglyph deserts the cathedral, and betakes itself to blazoning the donjon keep, in order to lend prestige to feudalism. The cathedral itself, that edifice formerly so dogmatic, invaded henceforth by the bourgeoisie, by the community, by liberty, escapes the priest and falls into the power of the artist. The artist builds it after his own fashion. Farewell to mystery, myth, law. Fancy and caprice, welcome. Provided the priest has his basilica and his altar, he has nothing to say. The four walls belong to the artist. The architectural book belongs no longer to the priest, to religion, to Rome; it is the property of poetry, of imagination, of the people. Hence the rapid and innumerable transformations of that architecture which owns but three centuries, so striking after the stagnant immobility of the Romanesque architecture, which owns six or seven. Nevertheless, art marches on with giant strides. Popular genius amid originality accomplish the task which the bishops formerly fulfilled. Each race writes its line upon the book, as it passes; it erases the ancient Romanesque hieroglyphs on the frontispieces of cathedrals, and at the most one only sees dogma cropping out here and there, beneath the new symbol which it has deposited. The popular drapery hardly permits the religious skeleton to be suspected. One cannot even form an idea of the liberties which the architects then take, even toward the Church. There are capitals knitted of nuns and monks, shamelessly coupled, as on the hall of chimney pieces in the Palais de Justice, in Paris. There is Noah's adventure carved to the last detail, as under the great portal of Bourges. There is a bacchanalian monk, with ass's ears and glass in hand, laughing in the face of a whole community, as on the lavatory of the Abbey of Bocherville. There exists at that epoch, for thought written in stone, a privilege exactly comparable to our present liberty of the press. It is the liberty of architecture.
