(View exact match)hypocaustCATEGORY: structure
DEFINITION: A Roman heating system in which a floor of tile and concrete, sometimes with mosaic, was supported on low tiled pillars to allow the hot air from a furnace to circulate beneath it. Warm air, heated in an outside stokehole, circulated under the raised floor and also often entered room through vents above floor level. The gases escaped up box flue tiles at intervals around the walls, thus also warming them. This heating system in baths (thermae) and houses gave a central-heating effect. Examples are found from about 100 BC onward.

RichboroughSYNONYMS OR RELATED TERMS: ancient Rutupiae
DEFINITION: The site of a Roman port in Kent, England, just north of Sandwich. After the Roman invasion of Britain in 43 AD, Richborough / Rutupiae was established to guard the Wantsum Channel separating the island of Thanet from the rest of Kent. Extant remains of Richborough Castle include the north wall of a Saxon Shore fort, possibly built in the 3rd century. The fort was equipped with a military bath-suite, of which the hypocaust survives, and an external amphitheater. Closeby is the site of the landing of the Saxon leaders Hengist and Horsa in 449 AD. It is also starting-point for the Roman road, Watling Street, to Chester via London. The site is now 5 km inland and no longer on the coast, following silting of the Wantsum Channel.box flueCATEGORY: artifact
DEFINITION: A brick of four terra cotta tiles which were joined together to conduct the furnace-heated air of a Roman (hypocaust) heating system. The tiles were joined at the edges and open at the top and the bottom. The air was directed through them up the walls to escape at the eaves. The exposed faces of the box-flue tiles were often decorated in relief to provide a key for the wall plaster which normally covered them.flue tileCATEGORY: artifact
