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 In the sixteenth century many Flemish tiles were brought to England, and superseded those of English manufacture. In the Middle Ages no branch of art was neglected. Even the smith, who made the ironwork for the doors, locks, and screens, was an artist, and took pains to adapt his art to the style of architecture prevailing in his time. Norman doors are remarkable for their beautifully ornamented hinges. They have curling scrollwork, and a large branch in the form of the letter C issuing from the straight bar near the head. Early English doors have much elaborate scrollwork, with foliage and animals' heads. During the Decorated period the hinges are simpler, on account of the carved panelling on the doors, and they continue to become plainer in the subsequent period. The knockers on the doors often assume very grotesque forms, as at Durham Cathedral. The mediaeval plumber was also an artist, and introduced shields of arms, fleur-de-lis, and other devices, for the enrichment of spires, and pipes for carrying off water from the roof.
