SCREEN, any construction subdividing one part of a building from another - as a choir, chantry, chapel, &c. The earliest screens are the low marble podia, shutting off the chorus cantantium in the Roman basilicas, and the perforated cancelli enclosing the bema, altar, and seats of the bishops and presbyters. The chief screens in a church are those which enclose the choir or the place where the breviary services are recited. This is done on the Continent, not only by doors and screen work, but also, when these arc of open work, by curtains, the laity having no part in these services. In England screens were of two kinds, one of open wood work, generally called rood-sereens or juries (which see), and which the French call grilles, el6turcs die chceur ; the other, massive enclosures of stone work enriched with niches, tabernacles, canopies, pinnacles, statues, crestings, &c., as at Canterbury, York, GIcucester, and many- other places both in England and abroad.
