I have already given the name of one of the master-masons who were associated with this great pile of buildings, where the sound of chisel and mallet can have scarcely ever ceased from the twelfth century to the sixteenth. But Jean Davi's work was necessarily one of the last finishing touches upon a building that others had reared in the mass for him to decorate in detail. The various churches that had been consecrated on the same spot have been recorded in their turn, from the first primitive shrine of St. Mellon, in the fourth century, to that greater fane seen by the Conqueror, which was almost entirely burnt in 1200. The lower part of the Tour St. Romain is certainly a part of the cathedral St. Maurilius consecrated. To say exactly when the work of reconstruction was begun which St. Louis saw completed has puzzled antiquarians far more diligent and learned than I am. But M. Viollet le Duc has pointed to unmistakable signs of work earlier than the rest in the two circular chapels of the apse, in the chapels of the transept, and in the two side-doors of the western facade, which open to the aisles. M. de Beaurepaire has also demonstrated, from a close study of the Chapterhouse accounts, that when Richard de Malpalu was dean in 1200, one Jean d'Andeli is spoken of as "Cementario, tunc _magistro_ fabrice ecclesiae rothomagensis." He was also a relation of one of the canons. The _Chronique du Bec_ gives the credit of initiating the design to Ingelramus, or Enguerrand, from 1200 to 1214; but this does not contradict the possibility of partners in the work, and that the choir at any rate was done before the Norman influence was much affected by the Ile de France, may be seen at once in the fourteen tall and strong round pillars with their simple capitals and massive round arches, which produce a very fine effect of pure solidity amongst the lighter pointed work surrounding them. After Enguerrand came "Durand le Machon," who dwelt in the same house that Jean d'Andeli had held on lease, and after him, again, the name of Gautier de St. Hilaire occurs before that of Jean Davi towards the end of the thirteenth century.
