Exterior''
The back part of the house was centred around the peristyle much as the front centred on the atrium. The peristylium was a small garden often surrounded by a columned passage, the model of the medieval cloister. Surrounding the peristyle were the bathrooms, kitchen and summer triclinium. The kitchen was usually a very small room with a small masonry counter wood-burning stove. The wealthy had a slave who worked as a cook and spent nearly all his or her time in the kitchen. During a hot summer day the family ate their meals in the summer triclinium to stave off the heat. Most of the light came from the compluvium and the open peristylium.
There were no clearly defined separate spaces for slaves or for women. Slaves were ubiquitous in a Roman household and slept outside their masters' doors at night; women used the atrium and other spaces to work once the men had left for the forum. There was also no clear distinction between rooms meant solely for private use and public rooms, as any private room could be opened to guests at a moment's notice.
