Illustrated Architecture Dictionary
A window casement, fixed or hinged, with glazed bars set diagonally.
In churches and Tudor Revival style, usually leaded windows.
Roman lattice is an openwork system of rectangular bars crossing each other to make a pattern of triangles (usually, but not always, right triangles) within repetitive squares.
The Latin word for Roman lattice or grating is transenna. Transenna is derived from the Latin term for a net for catching birds, which the form resembles.
In ancient times these patterned squares were arranged to form both railings and infill for openings. For railings, the materials could be wood, bronze, or stone. For openings, especially in monumental structures, the lattice would usually be stone, preferably marble, with the openings filled with a translucent material, often thin sheets of alabaster.
