The ancient church of San Michele in Orto was demolished by order of the Commune in the thirteenth century, to make way for a piazza for the grain and corn market, in the centre of which Arnolfo di Cambio built a loggia in 1280. Upon one of the pilasters of this loggia there was painted a picture of the Madonna, held in highest reverence by the frequenters of the market; a special company or sodality of laymen was formed, the Laudesi of Our Lady of Or San Michele, who met here every evening to sing laudi in her honour, and who were distinguished even in mediæval Florence, where charity was always on a heroic scale, by their munificence towards the poor. "On July 3rd, 1292," so Giovanni Villani writes, "great and manifest miracles began to be shown forth in the city of Florence by a figure of Holy Mary which was painted on a pilaster of the loggia of San Michele in Orto, where the grain was sold; the sick were healed, the deformed made straight, and the possessed visibly delivered in great numbers. But the preaching friars, and the friars minor likewise, through envy or some other cause, would put no faith in it, whereby they fell into much infamy with the Florentines. And so greatly grew the fame of these miracles and merits of Our Lady that folk flocked hither in pilgrimage from all parts of Tuscany at her feasts, bringing divers waxen images for the wonders worked, wherewith a great part of the loggia in front of and around the said figure was filled." In spite of ecclesiastical scepticism, this popular devotion ever increased; the company of the Laudesi, amongst whom, says Villani, was a good part of the best folk in Florence, had their hands always full of offerings and legacies, which they faithfully distributed to the poor.

The wonderful tidings roused even Guido Cavalcanti from his melancholy musings among the tombs. As a sceptical philosopher, he had little faith in miracles, but an esprit fort of the period could not allow himself to be on the same side as the friars. A delightful via media presented itself; the features of the Madonna in the picture bore a certain resemblance to his lady, and everything was at once made clear. So he took up his pen, and wrote a very beautiful sonnet to his friend, Guido Orlandi. It begins: "A figure of my Lady is adored, Guido, in San Michele in Orto, which, with her fair semblance, pure and tender, is the great refuge and harbour of sinners." And after describing (with evident devotional feeling, in spite of the obvious suggestion that it is the likeness of his lady that gives the picture its miraculous powers) the devotion of the people and the wonders worked on souls and bodies alike, he concludes: "Her fame goeth through far off lands: but the friars minor say it is idolatry, for envy that she is not their neighbour." But Orlandi professed himself much shocked at his friend's levity. "If thou hadst said, my friend, of Mary," so runs the double sonnet of his answer, "Loving and full of grace, thou art a red rose planted in the garden; thou wouldst have written fittingly. For she is the Truth and the Way, she was the mansion of our Lord, and is the port of our salvation." And he bids the greater Guido imitate the publican; cast the beam out of his own eye and let the mote alone in those of the friars: "The friars minor know the divine Latin scripture, and the good preachers are the defenders of the faith; their preaching is our medicine."

One of the most terrible faction fights in Florentine history raged round the loggia and oratory on June 10th, 1304. The Cavalcanti and their allies were heroically holding their own, here and in Mercato Vecchio, against the overwhelming forces of the Neri headed by the Della Tosa, Sinibaldo Donati and Boccaccio Adimari, when Neri Abati fired the houses round Or San Michele; the wax images in Our Lady's oratory flared up, the loggia was burned to the ground, and all the houses along Calimara and Mercato Nuovo and beyond down to the Ponte Vecchio were utterly destroyed. The young nobles of the Neri faction galloped about with flaming torches to assail the houses of their foes; the Podestà with his troops came into Mercato Nuovo, stared at the blaze, but did nothing but block the way. In this part of the town was all the richest merchandise of Florence, and the loss was enormous. The Cavalcanti, against whom the iniquitous plot was specially aimed, were absolutely ruined, and left the city without further resistance.

The pilaster with Madonna's picture had survived the fire, and the Laudesi still met round it to sing her praises. But in 1336 the Signoria proposed to erect a grand new building on the site of the old loggia, which should serve at once for corn exchange and provide a fitting oratory for this new and growing cult of the Madonna di Orsanmichele. The present edifice, half palace and half church, was commenced in 1337, and finished at the opening of the fifteenth century. The actual building was in the hands of the Commune, who delegated their powers to the Arte di Por Sta. Maria or Arte della Seta. The Parte Guelfa and the Greater Guilds were to see to the external decoration of the pilasters, upon each of which tabernacles were made to receive the images of the Saints before which each of the Arts should come in state, to make offerings on the feasts of their proper patrons; while the shrine itself, and the internal decorations of the loggia (as it was still called), were left in the charge and care of the Laudesi themselves, the Compagnia of Orsanmichele, which was thoroughly organised under its special captains. It is uncertain whom the Arte della Seta employed as architect; Vasari says that Taddeo Gaddi gave the design, others say Orcagna (who worked for the Laudesi inside), and more recently Francesco Talenti has been suggested. Benci di Cione and Simone di Francesco Talenti, who also worked at the same epoch upon the Duomo, were among the architects employed later. The closing in of the arcades, for the better protection of the tabernacle, took away the last remnants of its original appearance as an open loggia; and, shortly before, the corn market itself was removed to the present Piazza del Grano, and thus the "Palatium" became the present church. The extremely beautifully sculptured windows are the work of Simone di Francesco Talenti.

There are fourteen of these little temples or niches, partly belonging to the Greater and partly to the Lesser Arts. It will be seen that, while the seven Greater Arts have each their niche, only six out of the fourteen Minor Arts are represented. Over the niches are tondi with the insignia of each Art. The statues were set up at different epochs, and are not always those that originally stood here–altered in one case from significant political motives, in others from the desire of the guilds to have something more thoroughly up to date–the rejected images being made over to the authorities of the Duomo for their unfinished façade, or sent into exile among the friars of Santa Croce. In 1404 the Signoria decreed that, within ten years from that date, the Arts who had secured their pilasters should have their statues in position, on pain of losing the right. But this does not seem to have been rigidly enforced.

WINDOW OF OR SAN MICHELE

Beginning at the corner of the northern side, facing towards the Duomo, we have the minor Art of the Butchers represented by Donatello's St. Peter in marble, an early and not very excellent work of the master, about 1412 (in a tabernacle of the previous century); the tondo above containing their arms, a black goat on a gold field, is modern. Next comes the marble St. Philip, the patron saint of the minor Art of the Shoemakers, by Nanni di Banco, of 1408, a beautiful and characteristic work of this too often neglected sculptor. Then, also by Nanni di Banco, the Quattro incoronati, the "four crowned martyrs," who, being carvers by profession, were put to death under Diocletian for refusing to make idols, and are the patrons of the masters in stone and wood, a minor Art which included sculptors, architects, bricklayers, carpenters, and masons; the bas-relief under the shrine, also by Nanni, is a priceless masterpiece of realistic Florentine democratic art, and shows us the mediæval craftsmen at their work, the every-day life of the men who made Florence the dream of beauty which she became; above it are the arms of the Guild, in an ornate and beautiful medallion, by Luca della Robbia. The following shrine, that of the Art of makers of swords and armour, had originally Donatello's famous St. George in marble, of 1415, which is now in the Bargello; the present bronze (inappropriate for a minor Art, according to the precedent of the others) is a modern copy; the bas-relief below, of St. George slaying the dragon, is still Donato's. On the western wall, opposite the old tower of the Guild of Wool, comes first a bronze St. Matthew, made together with its tabernacle by Ghiberti and Michelozzo for the greater Guild of Money-changers and Bankers (Arte del Cambio), and finished in 1422. The Annunciation above is by Niccolò of Arezzo, at the close of the Trecento. The very beautiful bronze statue of St. Stephen, by Ghiberti, represents the great Guild of Wool, Arte della Lana; originally they had a marble St. Stephen, but, seeing what excellent statues had been made for the Cambio and the Calimala Guilds, they declared that since the Arte della Lana claimed to be always mistress of the other Arts, she must excel in this also; so sent their St. Stephen away to the Cathedral, and assigned the new work to Ghiberti (1425). Then comes the marble St. Eligius, by Nanni di Banco (1415), for the minor Art of the Maniscalchi, which included farriers, iron-smiths, knife-makers, and the like; the bas-relief below, also by Nanni, represents the Saint (San Lò he is more familiarly called, or St. Eloy in French) engaged in shoeing a demoniacal horse.

On the southern façade, we have St. Mark in marble for the minor Art of Linaioli and Rigattieri, flax merchants and hucksters, by Donatello, (about 1412).[32] The Arte dei Vaiai e Pellicciai, furriers, although a greater Guild, seems to have been contented with the rather insignificant marble St. James, which follows, of uncertain authorship, and dating from the end of the Trecento; the bas-relief seems later. The next shrine, that of the Doctors and Apothecaries, the great Guild to which Dante belonged and which included painters and booksellers, is empty; the Madonna herself is their patroness, but their statue is now inside the church; the Madonna and Child in the medallion above are by Luca della Robbia. The next niche is that of the great Arte della Seta or Arte di Por Santa Maria, the Guild of the Silk-merchants, to which embroiderers, goldsmiths and silversmiths were attached; the bronze statue of their patron, St. John the Evangelist, is by Baccio da Montelupo (1515), and replaces an earlier marble now in the Bargello; the medallion above with their arms, a gate on a shield supported by two cherubs, is by Luca della Robbia.
