The principal schools that fostered all forms of Decorative Art were the Guilds of St. Luke. They sprang up in every prosperous city, and were very close corporations of trades unionism. The idea probably originated in Italy. A Society of St. Luke was established in Venice before 1290, and another in Florence in 1349. One Gerard de Groote organized a brotherhood of this kind in Cologne in the fourteenth century; and Societies of St. Luke were founded in Flanders in the fifteenth century. These Guilds exerted the greatest influence upon taste and skill, for in these Societies of Guilds of St. Luke, side by side with the Masters of Painting and Sculpture, were placed what we may call the Masters of the Decorative Arts. There were workers in stone and marble including mosaics in colour for the decoration of churches and chapels; workers in enamel and ceramics for vases, panelling and pavements; workers in wood, sculptors and carvers for the altar fronts, canopies, choir stalls, etc. (these _menuisiers_ also worked in marquetry and _intarsie_, and produced furniture for the sacristy, coffers, _bahuts_, etc., and pontifical seats); glass-workers who produced windows, panels and embroideries with glass beads for decoration; metalworkers, including goldsmiths, bronze-workers, who made sacred vessels, luminaries, fonts ornamented with _repoussé_-work, chiselling, engraving, incrustation with precious stones and _niello-niellure_; leather-workers (including makers of harness for wars and tourneys); gilders, setters of jewels; bookbinders; illuminators and painters of manuscripts; weavers and embroiderers of tapestries, silken stuffs, etc. Society benefited by development of these arts very greatly, and the sumptuous adornment of the churches soon extended to private dwellings. Carved panels, or panels inlaid with precious woods, soon decorated the walls of wealthy houses that were further enriched by magnificent tissues of silk and gold, tapestries or panels of stamped leather as a background for pictures beautifully framed in carved and gilt wood. In marquetry furniture, the most remarkable objects were the coffers for jewels, and the cabinets (_stipi_), in ebony, shell and ivory, embellished with gilt, bronze, and the dower chests, “_arches de mariage_.” CHAPTER II THE BURGUNDIAN PERIOD
