In ancient Rome, what role did the fauces play in the structure of a typical house?

The fauces in a typical ancient Roman house, or domus, served as the main entrance hall. This space was crucial as it functioned as the threshold between the public and private aspects of the home. Upon entering through the main doorway, visitors would first encounter the fauces before moving into deeper areas of the house. Its role as an entrance hall was significant, as it was often decorated and provided a transitional area where guests were received. The layout of Roman houses emphasized this importance, ensuring that the fauces was an accessible and prominent feature, setting the tone for the visitor's experience within the private residence.

In comparison, other areas of the house served different functions. The dining area, known as the triclinium, was specifically designed for meals, while bathing typically occurred in the balneum or a private bathroom area, both of which had distinct purposes separate from the fauces. Additionally, while some homes may have incorporated space for commercial activities, they wouldn't typically use the fauces for this function, as its primary role was to welcome guests and separate the private domestic life from the outside world.
