A sundial in a Roman house would typically be found in the peristylum, which is an open courtyard surrounded by columns. This area would allow the sundial to be placed outdoors where it can receive direct sunlight, which is essential for it to accurately tell the time based on the position of the sun's shadow. The peristylum served both functional and decorative purposes in Roman architecture and was often designed to be a pleasant garden space, making it a suitable location for outdoor timekeeping devices like a sundial.

The other areas mentioned, such as the kitchen or corridor, would not be practical locations for a sundial since they are typically enclosed spaces that might not receive adequate sunlight. The atrium, while an important central area of a Roman house, could sometimes have skylights or openings, but it is less common for sundials to be placed there compared to the peristylum where the outdoor conditions are more favorable.
