HYPOCAUST (Gr. inroicauQrov: &Ire, beneath, and Icaueiv, to See also:burn) , the See also:term given to the chamber formed under the floors of the See also:Roman See also:baths, through which the hot See also:air from the See also:furnace passed, sometimes to a single flue, as in the See also:case of the See also:tepidarium, but in the calidarium and sweating-See also:room to a See also:series of flues placed See also:side by side forming the lining of the walls. The See also:floor of the hot-air chamber consisted of tiles, 2 ft. square, laid on a See also:bed of See also:concrete; on this a series of See also:dwarf piers 2 ft. high were built of 8-in. square tiles placed about 16 in. apart, which carried the floor of the See also:hall or room; this floor was formed of a bed of concrete covered with layers of pounded bricks and See also:marble See also:cement, on which the marble See also:pavement in slabs or tesserae was laid. In colder countries, as for instance in See also:Germany and See also:England, the living rooms were' all heated in a similar way, and See also:round Treves (See also:Trier) both systems have been found in two or three Roman villas, with the one flue for the See also:ordinary rooms and several See also:wall flues for the hot baths. In England these hypocausts are found in every Roman See also:settlement, and the See also:chief See also:interest in these is centred in the magnificent See also:mosaic pavements with which the See also:principal rooms were laid. Many of the pavements found in See also:London and elsewhere havebeen preserved in the See also:British or the See also:Guildhall museums; and in some of the provincial towns, such as See also:Leicester and See also:Lincoln, they remain in situ many feet below the See also:present level of the See also:town.
