Chasse (casket)A chasse, châsse or box reliquary is a shape commonly used in medieval metalwork for reliquaries and other containers. To the modern eye the form resembles a house, though a tomb or church was more the intention, with an oblong base, straight sides and two sloping top faces meeting at a central ridge, often marked by a raised strip and decoration. From the sides there are therefore triangular "gable" areas. The casket usually stands on straight stumpy feet, and there is a hinged opening to allow access, either one of the panels, but not on the front face, or the wooden bottom; there is usually a lock.
Vitreous enamelVitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between . The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy". Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and another material (or more glass).
ReliquaryA reliquary (also referred to as a shrine, by the French term châsse, and historically including phylacteries) is a container for relics. A portable reliquary may be called a fereter, and a chapel in which it is housed a feretory. Relics may be the purported or actual physical remains of saints, such as bones, pieces of clothing, or some object associated with saints or other religious figures. The authenticity of any given relic is often a matter of debate; for that reason, some churches require documentation of the relic's provenance.
Medieval artThe medieval art of the Western world covers a vast scope of time and place, with over 1000 years of art in Europe, and at certain periods in Western Asia and Northern Africa. It includes major art movements and periods, national and regional art, genres, revivals, the artists' crafts, and the artists themselves. Art historians attempt to classify medieval art into major periods and styles, often with some difficulty.
