Tablinum - Directly behind the atrium was a room open on two sides, though both sides could be closed with curtains or folding doors, such as this lattice-style wooden door or this door with folding panels. The Roman domus was typically designed so that anyone standing in the vestibule could see straight through the atrium and tablinum to the colonnaded garden in the back of the house a very impressive vista! In this room the master of the house, the paterfamilias, would greet his many clients on their morning visits.
