CIBORIUM, ST. AMBROGIO.

The eastern portion of the basilica, which has three apses, is a survival of the ninth century building. The apses do not exactly correspond in direction with the later built body of the church, as is easily seen in looking up from the nave to the central apse. That they belong to the church built for the monks, and not to an earlier basilica, as their obvious priority to the rest of the building has led the supporters of the ninth century theory to suppose, is shown by there being three apses, and by the prolongation of the space in front of them for the choir, to accommodate the monks, who needed a place apart from the people for their special functions. In a very early basilica there would be but one apse, and it would start from the nave. The sanctuary is raised a few steps above the level of the nave, and in its midst, conspicuous and alone as it should be, beneath the noble curves of arch and cupola rises the four-sided canopy of the High Altar, upon four antique columns of red porphyry, glowing with deep colour and gilding against the rich darkness of the great mosaic in the tribune behind. The decoration of the canopy is of stucco. Moulded upon the flat pediments above the semicircular arches are gilded figures in relief against a background of deep blue; on the front, facing into the nave, Christ enthroned, giving the keys to Peter, and the law to Paul; on the back St. Ambrogio, protected by an angel behind him, stands between SS. Gervasio and Protasio, who present to him two kneeling Benedictine monks, one of whom holds in his hands a model of the canopy, and is thought to be Abbot Gaudenzio, appointed head of the monastery in 835; on the left side Madonna, with the Dove of the Holy Spirit on her head, is standing between two kneeling princesses, who lift their hands in supplication to her; on the right is St. Ambrogio and two princes, who also kneel and seem to beseech him. The friezes and bands of ornamentation are exceedingly rich, and very beautiful in design. At the corners are eagles, with their wings spread and fish between their claws. The canopy is an early thirteenth century restoration of a pre-existing one produced by Byzantine artists, probably in the time of Archbishop Angilberto, and wrecked by the fall of the cupola in 1196, little but the columns and the capitals surviving. The new work kept the Byzantine character of the old—the rigidity of the figures, the conventionalised draperies, the sacred symbols, though the spirit of a later age is visible in a certain rude attempt to give life to the heads.

Beneath the canopy the treasure which it was built to shelter still stands, the famous golden altar of Archbishop Angilberto. This altar is the largest and perhaps the most beautiful example known of the goldsmith’s art in the Carlovingian period. It is kept enclosed in a massive case, and a fee of five francs must be paid to the sacristan to see it. On St. Ambrose’s Day only is it uncovered to public view. The front of the altar is entirely faced with plates of fine gold divided into panels by borders of exquisite mosaic of enamel, and gold filigree work of delicate and various design, enriched with thickly-set gems, rubies, opals, sapphires, topaz and turquoise, cats’-eyes and every sort of strange-hued stone, some of great size, and edged with pearls. The panels are filled with figures in relief. In the middle, in a panel of oval form is Christ, with a jewelled halo, enthroned amid stars formed of precious stones. Around Him are the four Evangelic Beasts and the Apostles, three and three together. On either side are scenes from the Gospel story. The Resurrection, Ascension and Pentecost are sixteenth century restorations, quite out of keeping with the archaic character of the rest. The back and sides of the altar are of silver and of silver-gilt. On each of the sides there is a Greek cross of gold filigree set with gems and bordered with exquisite enamel, and around are figures of saints and angels, SS. Ambrose, Simpliciano, Gervasio and Protasio appearing on the right side, and on the left SS. Martin, Nabor, Nazario and Magno, the three latter being Milanese martyrs in the time of Diocletian and Decius. The back is divided into panels like the front, but in the middle there are four medallions. The two upper ones contain figures of the angels Michael and Gabriel. The two below are of great interest, as evidence of the origin and antiquity of the altar. In one is shown St. Ambrose crowning Angilberto, who has a halo of rectangular form, which signifies that he was living at the time of the representation; he offers a model of the altar to the Saint. The names Sanctus Ambrosius and Dominus Angilbertus are inscribed beside them. In the companion medallion we see Ambrose again, crowning Volvinus magister phaber (Master Volvinus the Smith), as the inscription describes him, the German artificer whom the Archbishop charged to make this altar, art at that time being far more advanced beyond the Alps than in Italy. The panels contain scenes from the legend of St. Ambrose; the Saint as a babe in the cradle attracting a swarm of bees by his honeyed mouth; journeying on horseback into Liguria, where he was prefect; flying at full gallop from Milan to avoid being Bishop, and admonished by a voice from on high to return; being baptized and ordained Bishop; celebrating Mass, while a cleric touches him on the back, showing how, as the legend relates, sleep has fallen on him and he is being transported in a vision to Tours, where in another panel he is represented laying the dead St. Martin in his tomb; again he appears preaching, inspired by an angel; treading beside the altar on the gouty foot of a bystander and healing it; seeing Christ in a dream, who announces to him his approaching death; offering his body to God as he dies; lastly, his dead body is being carried to Heaven by angels. These reliefs are very reminiscent of classic forms and have a surprising grace and freedom for the period. The representations of St. Ambrose’s story in particular are full of life and vigour, and show much beauty of composition and modelling, though they betray the era of their origin in certain awkwardnesses of proportion and grotesque attitudes. Here and there cameos of exquisite and evidently antique workmanship are let into the borders, and gems with Greek words cut in them; but perhaps the greatest beauty of all is the enamel—just beginning at that time to be used extensively in decorative art—and the delicate designs in which it is composed.

This gorgeous jewelled work, flashing out beneath the splendour of the canopy, seems to gather into a point all the glory of this rich interior. From the choir, which is raised several steps above the sanctuary, one can get a complete view of the mosaic decoration of the apse, a grand and imposing composition, with a colossal figure of Christ enthroned in the centre, lifting His hand in benediction, and on either side of Him SS. Gervasio and Protasio, and the Archangels Michael and Gabriel above. The names of the two martyrs are written beside them, letter beneath letter. Under the central figure there are three medallions; S. Satiro, brother of St. Ambrose, in the centre, and S. Marcellina, their sister, and S. Candida to right and left. The sides of the composition depict the story related by S. Gregory of Tours about St. Ambrose and represented on the altar; how he fell into a trance as he celebrated Mass and was rapt in spirit to Tours, where he performed the burial rite over the body of S. Martin. This mosaic is of the twelfth century, and though it follows the Byzantine style in arrangement and general treatment, it shows a tendency to abandon the old rigid conventions for the sake of more life and expression in the attitudes and draperies of the figures, and so sacrifices something of the decorative effect. The colour is very sombre, lacking the richness and glow of the best mosaic.

There is a marble episcopal seat of the ninth century in the choir. The stalls are very beautiful. Some are of the fourteenth century, as is also the triple seat on the right hand of the altar; the other stalls date from 1507. The designs carved upon them—trees and foliage, with small figures of men and animals, a peasant gathering grapes, a neglectful swineherd munching acorns, while the pig climbs the tree to reach some for itself, a man and a bear facing each other with comical hesitation beneath a tree, and other rustic scenes—are very graceful and delicate, and show a Renaissance spirit of gaiety.

The richly sculptured pulpit carries us back again to the earlier ages of the church. It is a very late twelfth century restoration of the pre-existing pulpit, which was ruined by the fall of the roof in 1196. An inscription on the side facing down the nave records that Guglielmus de Pomo, Superstes—chief priest or superior of the church—caused this and many other works to be done. It rests partly upon a Christian sarcophagus of the fifth or sixth century, and partly upon columns. The cover of the sarcophagus is crowded with figures in bas-relief, among which appear the effigies of the unknown couple, apparently of high rank, buried in it. On the side facing into the middle of the church, Christ is represented, seated among the Prophets, and on the other side He appears with the Apostles. Abraham sacrificing Isaac is the subject sculptured on one end, Elijah ascending in the chariot of fire on the other. These sculptures of the late Roman age, showing the decadence of a developed style, contrast strangely with the exuberant twelfth century decoration upon the other parts of the structure—ornamental borders and friezes with the characteristic curling stems that enmesh strange animals in endless pursuit of one another, innocent creatures, stags and hares chased by savage-fanged beasts, birds and grotesque humans forming caryatids, an ass playing the lyre, an eagle pecked by another bird, etc. Art has died and been born again in the interval between the old and the late work. In the twelfth century sculpture we see the wild rush of a new life, vigorous, cruel and merry, but at the same time penetrated by the pessimistic consciousness of youth. The difficulty of the sculptor in dealing with human figures is shown by the absurdly childish way in which the little scenes of Adam and Eve’s history, in the spaces beneath the arches, are represented. On the parapet of the pulpit at the back a Christian feast is sculptured.

The crypt beneath the choir was originally built in the ninth century, but is now completely modern. Descending into it you may look into the hallowed recess, where in an ornate silver shrine of very recent date lie the bodies of St. Ambrose and of the twin martyrs, Gervasio and Protasio, still beneath the high altar, where long ago the great bishop willed to lie.
