The Cathedral of the Cite is worthy of great protecting walls and there are few churches whose destruction would have been so sad a blow to the architecture of the Midi. Saint-Nazaire is typical at once of the originality of the southern builders, of their idealism, and their joyous freedom from conventional thrall. The facade, straight, and massive, has the frowning severity of an old donjon wall. Its towers are solid masses of heavy stone; instead of spires, there are crenellations; instead of graceful flying-buttresses at the sides, there are solid, upright supports on the firm, plain side-walls. This is the true old Romanesque. A few steps further, and the apse appears, as great a contrast to the body of the church as a bit of Mechlin lace to a coat-of-mail. A little tower with gargoyles, another with a fine-carved turret, windows whose delicate traceries could be broken by a blow, and an upper balustrade which would have been as easily crushed as an egg-shell in the hands of the lusty Huguenots,--these are the ornaments of its wall, as true XIV century Gothic as the nave is XII century Romanesque. It is sadly disappointing to find the Cloisters in uninteresting ruin, but the church within is so full of great beauty that all other things are unimportant. The windows glow in the glory of their glass, and the tombs, especially those of the lower Chapel of the Bishop, are wonderfully carved. The first burial place of de Montfort, terrible persecutor of his Church's foes, lies near the High Altar, and in the wall, there is a rude bas-relief representing his siege of Toulouse. All these admirable details are puny in comparison with the interior which contains them. It is to be feared that often, too little time is spent upon the nave. Even in mid-day, lighted by the southern sun, its beautiful, severe lines are mellowed but little, and one turns too instinctively to the Gothic, the greater lightness beyond. Yet it is a nave of exceedingly fine, rugged strength, and to pass on lightly, to belittle it in comparison with its brighter choir, is to wantonly miss in the great round columns, the heavy piers, and the dark tunnel vaulting, the conception of generations of men who had ever before their mind--and literally believed--"A mighty fortress is our God." The choir is of the XIV century, a day when the "beauty of holiness" seems to have been the Cathedral architect's ideal. Delicate, clustered columns from which Saints look down, long windows beautifully veined, a glorious rose at each transept's end, and high vault arches springing with a slender pointed grace, all these are of exquisite proportions; and the brilliant stained-glass adds a softening warmth of colour, but not too great a glow, to the cold fragility of the shafts of stone. Nothing in the Gothic art of the South, little of Gothic elsewhere, is more thoughtfully and lovingly wrought than this choir of Saint-Nazaire, and few churches in the Romanesque form are more finely
