The
domus included multiple rooms, indoor courtyards, gardens and beautifully painted walls that were elaborately laid out. The
vestibulum ('entrance hall') led into a large central hall: the
atrium, which was the focal point of the
domus and contained a statue of or an altar to the household gods. Leading off the atrium were
cubicula (bedrooms), a dining room
triclinium, where guests could eat dinner whilst reclining on couches, a
tablinum (living room or study), and the
culina (Roman kitchen). On the outside, and without any internal connection to the atrium, were
tabernae (shops facing the street). In cities throughout the Roman Empire, wealthy homeowners lived in buildings with few exterior windows. Glass
windows were not readily available:
glass production was in its infancy. Thus a wealthy Roman citizen lived in a large house separated into two parts, and linked together through the
tablinum or study or by a small passageway. Surrounding the atrium were arranged the master's family's main rooms: the small cubicula or bedrooms, the
tablinum, which served as a living room or study, and the
triclinium, or dining-room. Roman homes were like Greek homes. Only two objects were present in the atrium of Caecilius in
Pompeii: the
lararium (a small shrine to the
Lares, the household gods) and a small bronze box that stored precious family items. In the master bedroom was a small wooden bed and couch which usually consisted of some slight padding. As the
domus developed, the
tablinum took on a role similar to that of the study. In each of the other bedrooms there was usually just a bed. The
triclinium had three couches surrounding a table. The
triclinium often was similar in size to the master bedroom. The study was used as a passageway. If the master of the house was a banker or merchant, the study often was larger because of the greater need for materials. Roman houses lay on an axis, so that a visitor was provided with a view through the fauces, atrium, and
tablinum to the peristyle.
Interior architectural elements Vestibulum (
fauces): the
vestibulum was the main entrance hall of the Roman
domus. It is usually seen only in grander structures; however, many urban homes had shops or rental space directly off the streets with the front door between. The
vestibulum would run the length of these front
tabernae shops. This created security by keeping the main portion of the
domus off the street. In homes that did not have spaces for let in front, either rooms or a closed area would still be separated by a separate
vestibulum.
Atrium (: atria): the atrium was the most important part of the house, where guests and dependents (
clients) were greeted. The atrium was open in the center, surrounded at least in part by high-ceilinged porticoes that often contained only sparse furnishings to give the effect of a large space. In the center was a square roof opening called the
compluvium in which rain could come, draining inwards from the slanted tiled roof. Directly below the
compluvium was the
impluvium.
Impluvium: an
impluvium was basically a drained pool, a shallow rectangular sunken portion of the atrium to gather rainwater, which drained into an underground cistern. The
impluvium was often lined with marble and surrounded by a floor of small mosaic.
Fauces: these were similar in design and function to the
vestibulum, but were found deeper into the
domus. Separated by the length of another room, entry to a different portion of the residence was accessed by these passageways which would now be called halls, hallways, or corridors.
Tablinum: between the atrium and the peristyle was the
tablinum, an office of sorts for the
dominus, who would receive his clients for the morning
salutatio. The
dominus was able to command the house visually from this vantage point as the head of the social authority of the
pater familias.
Triclinium: the Roman dining room. The area had three couches,
klinai, on three sides of a low square table. The
oecus was the principal hall or salon in a Roman house, which was used occasionally as a
triclinium for banquets.
Alae: the open rooms (or alcoves) on each side of the atrium. Ancestral death masks, or
imagines, may have been displayed here. The wedding couch or bed, the
lectus genialis, was placed in the atrium, on the side opposite the door or in one of the
alae.
Cubiculum: bedroom. The floor mosaics of the
cubiculum often marked out a rectangle where the bed should be placed.
Culina: the
kitchen in a Roman house. The
culina was dark, and the smoke from the cooking fires filled the room as the best ventilation available in Roman times was a hole in the ceiling (the domestic
chimney would not be invented until the 12th century CE). This is where slaves prepared food for their masters and guests in Roman times.
Posticum: a servant's entrance is also used by family members wanting to leave the house unobserved. ==Exterior==
