In the centre of the peristyle was an open court, which contained the impluvium.
Still he sprang from the couch, groped his way to the door, opened it, and entered the impluvium that adjoined his bedroom.
The hall led into a further room, which was open in the centre to the sky, like the impluvium of a Roman house.
Beyond the impluvium is the place of a small altar for the worship of the Lares.
In the better houses a fountain was often placed in the middle of the impluvium.
