He was, in effect, the first of the commendatory abbots, a system which Julien de Baleure rightly calls "vraye sappe de l'état monastique et ruine des bons monastères,"[91] since under it the rule and revenues of the abbey passed into the hands of a stranger, who often wholly neglected his charge, or, if he visited it at all, paid only infrequent, ceremonial calls. Jean de Bourbon, though Bishop of Puy when Charles VII. recommended him to the choice of the monks of Cluny, was not a member of any monastic order; nevertheless, while still remaining the "grand seigneur," he appears to have done something to re-establish discipline in the monastery. It soon became apparent to him that the frequent visits of distinguished persons to his palace within the church precincts, were a menace to the peace of the cloister. He accordingly bought land from the monks, and built his palace adjoining the great gate, one arch of which was reserved for his private entrance. The building has undergone some modifications, but it remains a good example of fifteenth-century work, especially the windows, which have the typical flat arch of the period, and drip-stones with finely sculptured heads for corbels. On the east side, a later age has painted imitations of similar windows upon the stone wall. Within the palace are some handsome staircases and doors, and two excellent chimney-pieces, restored, showing the arms of Jean de Bourbon, of the Bishopric of Puy, and of the Abbey and Town of Cluny. The arms of the town are a silver key, on azure, with the ring below; those of the abbey are two golden keys crossed by a sword with silver blade, the hilt downwards. The musée lapidaire on the ground floor is full of interesting relics. They need not all be catalogued here, but I must point out two or three of the best. Probably the oldest relic there is a triangular memorial stone, in the corner, on the left of the fire-place, with the epitaph of Aimard (Sanctus Aimardus), third abbot of Cluny, who died in 964. Until 1872, this stone formed the threshold of a house in the town. Another relic, not to be missed, is the pierre tombale of St. Hugues (Abbot from 1046-1109), which is over the door opposite to the entrance; there is also the urn that contained his heart.
