SUSPENSU'RA. In general, any building or flooring raised from the ground by being supported upon arches, pillars, or piles; and especially applied to the flooring of a bath-room, when it is suspended over the flues of a furnace upon low pillars in order that the warm vapour may circulate freely under it (Vitruv. v. 10. 2. Senec. Ep. 90. Pallad. i. 40. 2.), as in the annexed example (Suspensura/1.1) showing the section of a bath-room, discovered in an ancient Roman villa at Tusculum, in which the floor of the room is supported upon tubular tiles, themselves hollow and perforated down the sides to admit the vapour.
