how were roman houses decorated
Under Floor Heating (hypocaust). Rich Roman houses had central heating which was under the floors. This heating system was called a hypocaust. The floors were supported on stacks of tiles (pilae) and hot air was circulated under the floor from a furnace stoked outside the building. Mosaic Floors. Mosaic have been found on the floors of many Roman buildings. Rich Romans decorated the floors of their main rooms with mosaics-tiny coloured stones (tesserae). These were stuck to the floor with mortar, a type of cement. Each mosaic used thousands of pieces to make a pattern. Mosaic floors were a statement of wealth and importance.
