presented by the seven greater arts, by six of the fourteen lesser arts, and by the Magistrato della Mercanzia, that magistracy which governed all the guilds,[95] their banners are set up even to this day. The great Guild of Wool was already responsible for the Duomo, and it was for this reason, it might seem, that to the Guild of Silk was given the care of Or San Michele; not altogether without jealousy, it might seem, for when they had asked leave to place the image of their saint in one of the niches there, all the other guilds had demanded a like favour, thus in an especial manner marking the place as the Church of the Merchants, the true _popolo_; the great popular shrine of Florence, therefore, since Florence was a city of merchants. It is on the south side, in the niche nearest to Via Calzaioli, that the Guild of Silk set its statue of St. John the Evangelist by Baccio da Montelupo; next to it is an empty niche belonging to the Guild of Apothecaries and Doctors. Here a Madonna and Child by Simone Ferrucci once stood, but, owing to a rumour current in the seventeenth century, that Madonna sometimes moved her eyes, the statue was placed inside the church, so that the crowd which always collected to see this miracle might no longer stop the way. In the next niche the Furriers placed a statue of St. James by Nanni di Banco, and beyond, the Guild of Linen set up a statue of St. Mark by Donatello. On the west, in the first niche, is S. Lo, the patron of the Furriers, carved by Nanni di Banco, and beyond, St. Stephen, set there by the Guild of Wool and carved by Ghiberti; while next to him stands St. Matthew, set there by the Bankers and carved by Ghiberti, and cast in 1422 by Michelozzo. On the north, Donatello's statue of St. George used to fill the first niche, somewhat shallower than the rest owing to a staircase inside the church, but it was removed to the Bargello for fear of the weather: the beautiful relief, also by Donatello, below the copy, is still in its place, under the St. George of the Armourers. The four statues in the next niche were placed there by the Guilds of Sculptors, Masons, Smiths, and Bricklayers; they are the work of Nanni di Banco. Further, is the St. Philip of the Shoemakers, again by Nanni di Banco, and the St. Peter of the Butchers, by Donatello. On the east stands St. Luke, placed there by the Notaries, and carved by Giovanni da Bologna; the great bronze group of Christ and St. Thomas, the gift of the Magistrato della Mercanzia, the governor of all the guilds; and the St. John Baptist, the gift of the Calimala, and the work of Ghiberti: this last was the first statue placed here--in 1414.
