In Roman architecture, what function does the 'impluvium' serve?

The impluvium is an architectural feature commonly found in Roman houses, specifically in the atrium. It is a shallow pool or basin located in the center of the atrium that serves the purpose of collecting rainwater from the opening in the roof known as the compluvium. This design is not only functional, as it provides a source of water for domestic use, but it also enhances the aesthetic quality of the home by allowing natural light to permeate the space and creating a cooling effect through evaporation.

The collection of rainwater was particularly important in places where water supply could be inconsistent, making the impluvium a vital element of Roman domestic architecture. This worked in conjunction with other systems for storing and distributing water throughout the house, showcasing the Romans' advanced understanding of architecture and their emphasis on practicality combined with beauty.
