Towards the middle of the thirteenth century [55] the cathedral of Saint Etienne was complete in its main outlines: what remained was the building of the great tower, and all that various labour of final decoration which it would take more than one generation to accomplish. Certain circumstances, however, not wholly explained, led to a somewhat rapid finishing, as it were out of hand, yet with a marvellous fulness at once and grace. Of the result much has perished, or been transferred elsewhere; a portion is still visible in sumptuous relics of stained windows, and, above all, in the reliefs which adorn the western portals, very delicately carved in a fine, firm stone from Tonnerre, of which time has only browned the surface, and which, for early mastery in art, may be compared with the contemporary work of Italy. They come nearer than the art of that age was used to do to the expression of life; with a feeling for reality, in no ignoble form, caught, it might seem, from the ardent and full-veined existence then current in these actual streets and houses. Just then Auxerre had its turn in that political movement which broke out sympathetically, first in one, then in another of the towns of France, turning their narrow, feudal institutions into a free, communistic life--a movement of which those great centres of popular devotion, the French cathedrals, are in many instances the monument. Closely connected always with the assertion of individual freedom, alike in [56] mind and manners, at Auxerre this political stir was associated also, as cause or effect, with the figure and character of a particular personage, long remembered. He was the very genius, it would appear, of that new, free, generous manner in art, active and potent as a living creature. As the most skilful of the band of carvers worked there one day, with a labour he could never quite make equal to the vision within him, a finely-sculptured Greek coffin of stone, which had been made to serve for some later Roman funeral, was unearthed by the masons. Here, it might seem, the thing was indeed done, and art achieved, as far as regards those final graces, and harmonies of execution, which were precisely what lay beyond the hand of the medieval workman, who for his part had largely at command a seriousness of conception lacking in the old Greek. Within the coffin lay an object of a fresh and brilliant clearness among the ashes of the dead--a flask of lively green glass, like a great emerald. It might have been "the wondrous vessel of the Grail." Only, this object seemed to bring back no ineffable purity, but rather the riotous and earthy heat of old paganism itself. Coated within, and, as some were persuaded, still redolent with the tawny sediment of the Roman wine it had held so long ago, it was set aside for use at the supper which was shortly to celebrate the completion of the masons' work.
