This prelate--generally counted as the sixty-second occupant of the see--seems at first to have united the adjacent churches of St. Stephen and St^{e} Marie on the Ile de la Cité, and then (without immediately and totally destroying them) to have commenced a new one on the same site, of which Pope Alexander III. laid the foundation-stone in 1163. Rapid progress must have been made with the work, for it is certain that in 1185 Heraclitus, patriarch of Jerusalem, officiated at the altar, in front of which, in the year following, Geoffrey, Count of Brittany, son of Henry II. of England, was buried. Maurice de Sully provided for the continuation of the work after his death, which took place in 1196. By his will he left five thousand _livres_ in order that the choir might be roofed with lead. At this time, according to Viollet-le-Duc, considerable progress must have been made with the nave. Maurice de Sully was succeeded by Eudes de Sully (1197-1208), on whose death the see was occupied, until 1219, by Pierre de Nemours. Towards 1223 the west front was completed to the base of the great gallery, and by 1235 the towers were left much as we see them to-day. The spires, which it is generally admitted they were intended to carry, were never added. Between the years 1235 and 1240, a fire seems to have broken out at Notre Dame. On this subject history is silent, but that it did serious damage is maintained by Viollet-le-Duc on what appear to be sufficient grounds. According to him, repair was made in haste, so that rose windows, flying buttresses and other structural details were ruthlessly sacrificed. The west front seems to have escaped mutilation. Up to 1245 the cathedral, vast as was its area, possessed either no chapels at all, or chapels of inconsiderable dimensions. In that year, however, the addition of new chapels was proceeded with. It would appear that, shortly after, the plainness of the transept fronts in comparison with the splendidly decorated west façade was acutely felt. In 1257, Jean de Chelles was engaged on reconstructing the southern doorway. At this time St. Louis was King of France, and Renaud de Corbeil bishop of Paris. The northern door and the chapels next the transepts on either side were altered immediately after the southern entrance. In 1351, Jean Ravy and Jean de Bouteiller were engaged about the cathedral as sculptors.
