When the Perpendicular style was in vogue the art of the glass-painter degenerated, as did that of the architect. Stained glass was little used, and the artists painted with enamel colours their designs upon the glass. The figures were larger than before, and the canopies of great size and with much architectural detail, landscapes and buildings appearing in the background. During this period inscriptions began to be used. In the sixteenth century the progress of the art was in the same direction. Large figures, and groups of figures, fill the whole window, and the existence of mullions is disregarded in the execution of the design. Glass-painting flourished until the Civil War period, and then died out.
English churches benefited much by the work of foreign artists. The great Florentine Francesco di Lievi da Gambassi visited this country. There is a letter dated 1434, written "to the master glass-painter Gambassi, then in Scotland, and who made works in glass of various kinds, and was held to be the best glass-painter in the world." How much must we regret the destruction of the windows made by this excellent artist in Holyrood chapel and elsewhere by fanatical mobs! The Fairford windows are perhaps the finest and most interesting in England. The story runs that they were made in Germany for a church in Rome, and that the vessel conveying them was captured by an English ship; and as the noble church at Fairford was then being built, the glass was sent there and given to it. Shiplake Church, Oxfordshire, has some of the beautiful glass which once adorned the ruined church of St. Bertin at St. Omer, plundered during the French Revolution.
Some good work was accomplished in the seventeenth century by English artists, who practised enamel painting, notably by Jervais, who in 1717 executed from designs by Sir Joshua Reynolds the beautiful west window of New College Chapel, Oxford.
The floors of our churches were enriched with inlaid tiles. Various patterns and designs were impressed upon them when the clay was moist, a metallic glaze covered the surface, and then the tiles were placed in the furnace. Many designs are found on ancient tiles, such as heraldic devices, monograms, sacred symbols with texts, architectural designs, figures, and patterns. The age of the tiles may be determined by comparing the designs imprinted upon them with the architectural decorations belonging to particular periods. In the sixteenth century many Flemish tiles were brought to England, and superseded those of English manufacture.
