Let us now proceed along the Via Calzaioli (which means street of the stocking-makers), running away from the Piazza del Duomo to the Piazza della Signoria. The fascinatingly pretty building at the corner, opposite Pisano's Baptistery doors, is the Bigallo, in the loggia of which foundling children used to be displayed in the hope that passers-by might pity them sufficiently to make them presents or even adopt them; but this custom continues no longer. The Bigallo was designed, it is thought, by Orcagna, and it is worth the minutest study.
The Company of the Bigallo, which is no longer an active force, was one of the benevolent societies of old Florence. But the greatest of these societies, still busy and merciful, is the Misericordia, whose head-quarters are just across the Via Calzaioli, in the piazza, facing the campanile, a company of Florentines pledged at a moment's notice, no matter on what they may be engaged, to assist in any charitable work of necessity. For the most part they carry ambulances to the scenes of accident and perform the last offices for the dead in the poorer districts. When on duty they wear black robes and hoods. Their headquarters comprise a chapel, with an altar by Andrea della Robbia, and a statue of the patron saint of the Misericordia, S. Sebastian. But their real patron saint is their founder, a common porter named Pietro Borsi. In the thirteenth century it was the custom for the porters and loafers connected with the old market to meet in a shelter here and pass the time away as best they could. Borsi, joining them, was distressed to find how unprofitable were the hours, and he suggested the formation of a society to be of some real use, the money to support it to be obtained by fines in payment for oaths and blasphemies. A litter or two were soon bought and the machinery started. The name was the Company of the Brothers of Mercy. That was in 1240 to 1250. To-day no Florentine is too grand to take his part, and at the head of the porter's band of brethren is the King.
Passing along the Via Calzaioli we come on the right to a noble square building with statues in its niches—Or San Michele, which stands on the site of the chapel of San Michele in Orto. San Michele in Orto, or more probably in Horreo (meaning either in the garden or in the granary), was once part of a loggia used as a corn market, in which was preserved a picture by Ugolino da Siena representing the Virgin, and this picture had the power of working miracles. Early in the fourteenth century the loggia was burned down but the picture was saved (or quickly replaced), and a new building on a much larger and more splendid scale was made for it, none other than Or San Michele, the chief architect being Taddeo Gaddi, Giotto's pupil and later the constructor of the Ponte Vecchio. Where the picture then was, I cannot say—whether inside the building or out—but the principal use of the building was to serve as a granary. After 1348, when Florence was visited by that ravaging plague which Boccaccio describes in such gruesome detail at the beginning of the "Decameron" and which sent his gay company of ladies and gentlemen to the Villa Palmieri to take refuge in story telling, and when this sacred picture was more than commonly busy and efficacious, it was decided to apply the enormous sums of money given to the shrine from gratitude in beautifying the church still more, and chiefly in providing a casket worthy of holding such a pictorial treasure. Hence came about the noble edifice of to-day.
A man of universal genius was called in to execute the tabernacle: Andrea Orcagna, a pupil probably of Andrea Pisano, and also much influenced by Giotto, whom though he had not known he idolized, and one who, like Michelangelo later, was not only a painter and sculptor but an architect and a poet. Orcagna, or, to give him his right name, Andrea di Cione, for Orcagna was an abbreviation of Arcagnolo, flourished in the middle of the fourteenth century. Among his best-known works in painting are the Dantesque frescoes in the Strozzi chapel at S. Maria Novella, and that terrible allegory of Death and Judgment in the Campo Santo at Pisa, in which the gay riding party come upon the three open graves. Orcagna put all his strength into the tabernacle of Or San Michele, which is a most sumptuous, beautiful and thoughtful shrine, yet owing to the darkness of the church is almost invisible. Guides, it is true, will emerge from the gloom and hold lighted tapers to it, but a right conception of it is impossible. The famous miraculous picture over the altar is notable rather for its properties than for its intrinsic beauty; it is the panels of the altar, which contain Orcagna's most exquisite work, representing scenes in the life of the Virgin, with emblematical figures interspersed, that one wishes to see. Only the back, however, can be seen really well, and this only when a door opposite to it—in the Via Calzaioli—is opened. It should always be open, with a grille across it, that passers-by might have constant sight of this almost unknown Florentine treasure. It is in the relief of the death of the Virgin on the back that—on the extreme right—Orcagna introduced his own portrait. The marble employed is of a delicate softness, and Orcagna had enough of Giotto's tradition to make the Virgin a reality and to interest Her, for example, as a mother in the washing of Her Baby, as few painters have done, and in particular, as, according to Ruskin, poor Ghirlandaio could not do in his fresco of the birth of the Virgin Herself. It was Orcagna's habit to sign his sculpture "Andrea di Cione, painter," and his paintings "Andrea di Cione, sculptor," and thus point his versatility. By this tabernacle, by his Pisan fresco, and by the designs of the Loggia de' Lanzi and the Bigallo (which are usually given to him), he takes his place among the most interesting and various of the forerunners of the Renaissance.
Within Or San Michele you learn the secret of the stoned-up windows which one sees with regret from without. Each, or nearly each, has an altar against it. What the old glass was like one can divine from the lovely and sombre top lights in exquisite patterns that are left; that on the centre of the right wall of the church, as one enters, having jewels of green glass as lovely as any I ever saw. But blues, purples, and reds predominate.
The tabernacle apart, the main appeal of Or San Michele is the statuary and stone-work of the exterior; for here we find the early masters at their best. The building being the head-quarters of the twelve Florentine guilds, the statues and decorations were commissioned by them. It is as though our City companies should unite in beautifying the Guildhall. Donatello is the greatest artist here, and it was for the Armourers that he made his S. George, which stands now, as he carved it in marble, in the Bargello, but has a bronze substitute in its original niche, below which is a relief of the slaying of the dragon from Donatello's chisel. Of this glorious S. George more will be said later. But I may remark now that in its place here it instantly proves the modernity and realistic vigour of its sculptor. Fine though they be, all the other statues of this building are conventional; they carry on a tradition of religious sculpture such as Niccolò Pisano respected, many years earlier, when he worked at the Pisan pulpit. But Donatello's S. George is new and is as beautiful as a Greek god, with something of real human life added.
Donatello (with Michelozzo) also made the exquisite border of the niche in the Via Calzaioli façade, in which Christ and S. Thomas now stand. He was also to have made the figures (for the Merchants' Guild) but was busy elsewhere, and they fell to Verrocchio, of whom also we shall have much to see and say at the Bargello, and to my mind they are the most beautiful of all. The John the Baptist (made for the Cloth-dealers), also on this façade, is by Ghiberti of the Baptistery gates. On the façade of the Via de' Lamberti is Donatello's superb S. Mark (for the Joiners), which led to Michelangelo's criticism that he had never seen a man who looked more virtuous, and if S. Mark were really like that he would believe all his words. "Why don't you speak to me?" he also said to this statue, as Donatello had said to the Zuccone. Higher on this façade is Luca della Robbia's famous arms of the Silk-weavers, one of the perfect things. Luca also made the arms of the Guild of Merchants, with its Florentine fleur-de-lis in the midst. For the rest, Ghiberti's S. Stephen, and Ghiberti and Michelozzo's S. Matthew, on the entrance wall, are the most remarkable. The blacksmith relief is very lively and the blacksmith's saint a noble figure.
The little square reliefs let into the wall at intervals are often charming, and the stone-work of the windows is very lovely. In fact, the four walls of this fortress church are almost inexhaustible. Within, its vaulted roof is so noble, its proportions so satisfying. One should often sit quietly here, in the gloom, and do nothing.
The little building just across the way was the Guild House of the Arte della Lana, or Wool-combers, and is now the head-quarters of the Italian Dante Society, who hold a conference every Thursday in the large room over Or San Michele, gained by the flying buttress-bridge. The dark picture on the outer wall is the very Madonna to which, when its position was at the Mercato Vecchio, condemned criminals used to pray on their way to execution.
Before we leave Or San Michele and the Arte della Lana, a word on the guilds of Florence is necessary, for at a period in Florentine history between, say, the middle of the thirteenth century and the beginning of the fifteenth, they were the very powerful controllers of the domestic affairs of the city; and it is possible that it would have been better for the Florentines had they continued to be so. For Florence was essentially mercantile and the guilds were composed of business men; and it is natural that business men should know better than noblemen what a business city needed. They were divided into major guilds, chief of which were the woollen merchants—the Arte della Lana—and the silk merchants—the Calimala—and it was their pride to put their riches at the city's service. Thus, the Arte della Lana had charge of the building of the cathedral. Each of the major guilds provided a Prior, and the Priors elected the Signoria, who governed the city. It is one of the principal charges that is brought against Cosimo de' Medici that he broke the power of the guilds.
