At the bottom of the nave, close to the entry of the choir, was placed, in after years, the tomb of Pope Gélase, and two altars, which, with a gate at the entrance, screened the monks from the eyes of the laymen. Here, too, against the pillars of the nave, were four large, painted, wooden statues, representing St. Hugues, holding the model of the church in his right hand, St. Mayeul, St. Odon, and St. Odilon.

The choir occupied the space between the two transepts; the sanctuary was carried on eight columns, three of which were of African marble, and three of Pentelic Greek marble, veined with blue, which St. Hugues brought from Italy by way of the Durance and the Rhône. The transept had many lateral chapels, and the east end, which was in semi-circular form, had five apsidal chapels, vaulted in half dome. A processional ambulatory circled the sanctuary and the tomb of St. Hugues, in front of which stood the great altar. Here, too, at opposite ends of the ambulatory, were placed the tombs of the Abbot Pons, and of Pierre le Vénérable. The vault of the apse was adorned with a fine painting, of the end of the eleventh, or beginning of the twelfth century, representing the Eternal Father borne upon clouds, one hand raised, and the other placed upon the Apocalypse sealed with seven seals. At his feet was the Lamb without Blemish, and about Him were winged figures of man, the lion, the eagle, and the ox.

But, in spite of the realism of the sculpture and the painting, in spite of the gorgeous tapestries, the golden candelabra, the pearl-encrusted ornaments of every kind, which the noblest men and women of the time, and of later times, showered upon Cluny, it is in the sense of spacious dignity and majesty, rather than in the sense of ostentation and magnificence, that we must interpret the words of Hildebrand de Mans, when he said that, "If it were possible for the inhabitants of the heavenly mansions to be happy in an abode fashioned by the hand of man, Cluny would be the angels' walk (ambulatorium angelorum)."

Nor was the church less noble without than within. From the circular chapels lying about her transepts and her apse, along the collateral and the double row of flying buttresses,[84] rising higher than the narthex, the eye was lifted, stage after stage, high above her lofty nave, to the mighty towers that rose to the sky, in witness, for ever, one would have said, of Him whose Dwelling was not made with hands.

The conventual buildings were on the south side of the basilica. From the principal south transept, a processional, and a smaller, door, opened upon the great romanesque cloister, of which a fragment here and there remains, built into the modern work. It was similar in style to the other buildings of the period. Further south were the Lady Chapel and the great refectory. Abutting on the great wall of the Abbey, by the side of the Grosne, was a mill and a thirteenth century bake-house, which still exist. Among the many other buildings, chapels, baths, schools for the young, pharmacy, workshops, dormitories, and stables, which are the necessary equipment of a great monastery, was a large infirmary, with its own cloister and refectory—a small establishment within the larger one. On the east side, extending to the fortified wall that enclosed the whole monastery, were the gardens of the abbey.

Such, in its essential aspects, was the "ambulatorium angelorum." How did its occupants live? What was the rule observed within those walls? The rule, as kept in those early days, was stern and exacting. The first of the regulations was silence, except at stated intervals. In the church, in the dormitory, in the refectory, in the kitchen, absolute silence, broken only by the summoning bell or by the chanting of prayers. Like ghosts, the sandalled monks glided about the echoing corridors; deaf mutes speaking by signs. The times for speech were the mornings, after chapter, and evenings after sexte. A parlour was reserved for the talkers, where, seated, book in hand, they might converse on spiritual and other topics. Yet they were recommended rather to remain in the cloister, and there meditate, read, pray, or copy manuscripts. This was the hour, too, for drying their clothes in the sun, for visiting the sick in the infirmary, for washing their cups, or for sharpening their knives on the grindstone in the cloister. Their daily food was limited to bread, vegetables, and fruits—meat was given only to the sick—eggs, cheese, and fish were allowed only occasionally, and nothing whatever might be eaten after complines. At certain seasons, the use of fat for flavouring vegetables was forbidden. If wine were permitted, on days of great solemnity, and during exhausting fasts, it must be free from spirituous seasoning, and from the spice that flatters the palates of the worldly. Still less was it permitted to drink hypocras, or oriental or Italian liqueurs—the "little wine" of the apostle was to suffice them. Only two repasts a day were allowed, except to the young, or to those engaged in specially hard work.

The monks might shave one another once in three weeks, chanting psalms the while, and not until the days of decadence were they shaved by a secular barber. "In bygone times," says the chronicler, "they were not shaved, they were skinned."[85] They might not bathe often, lest the habit should engender softness, and they did not usually indulge in full ablution more than twice a year—before Christmas and Easter. Sick monks, however, might bathe as often as they pleased.

The clothing allowed to the brothers consisted of a woollen shirt of dark colour—one for the day, another for the night. Their garments were rustic in form and substance; such as were worn by the peasants. Over the tunic was a scapular, with a hood or capuchon attached, and over all the frock was sometimes worn. Precious stuffs, silks, and gay colours were forbidden; for it was unfitting, said the statutes, that monks should be apparelled like brides for the nuptial chamber. The strict rule of St. Benedict allowed no furs; but a concession was made to the rigour of the Burgundian climate, and the monks might wear sheep-skin or goat-skin cloaks in winter, and fur boots for sleeping in, but no rich and costly skins from foreign lands—"For those who are softly clothed dwell in kings' Palaces." No monk might eat or drink at other than the regular hours; he might not go out at night, nor leave the monastery without the abbot's permission. When on a journey, he should receive only monastic hospitality, and, in any event, must never accept wine or meat; nor might he eat outside the gates, unless it were impossible for him to return home before sunset.
