CAVAEDIUM , in See also:

architecture, the Latin name for the central See also:hall or See also:court within a See also:Roman See also:house, of which five See also:species are described by See also:Vitruvius. (I) The Tuscanicum responds to the greater number apparently of those at See also:Pompeii, in which the timbers of the roof are framed together, so as to leave an open space in the centre, known as the See also:compluvium; it was through this opening that all the See also:light was received, not only in the hall itself, but in the rooms See also:round. The See also:rain from the roof was collected in gutters round the compluvium, and discharged from thence into a tank or open See also:basin in the See also:floor called the See also:impluvium. (2) In the tetrastylon additional support was required in consequence of the dimensions of the hall; this was given by columns placed at the four angles of the impluvium. (3) Corinthian is the See also:term given to the species where additional columns were required. (4) In the displuviatum the See also:roofs, instead of sloping down towards the compluvium, sloped outwards, the gutters being on the See also:outer walls; there was still an opening in the roof, and an impluvium to catch the rain falling through. This species of roof, Vitruvius states, is constantly in want of repair, as the See also:water does not easilyrun away, owing. to the stoppage in the rain-water pipes. (3) The testudinatum was employed when the hall was small and another floor was built over it; no example of this type has been found at Pompeii, and only one of the cavaedium displuviatum.
