Polished floors were significant in the lighting of Roman houses primarily because they multiplied the light from lamps. The shiny, reflective surfaces of polished floors helped to enhance the illumination provided by oil lamps used during that time. This reflective quality allowed light to bounce off the floors, effectively brightening the space and spreading light more evenly throughout the room.

In contrast, while aesthetic appeal is a valid consideration for polished floors, it does not directly relate to their function in lighting. The idea that polished floors absorbed sunlight is incorrect, as reflective surfaces serve to maximize light rather than minimize it. Furthermore, while polished floors might have contributed to a cooler environment, that aspect is not directly connected to the function of lighting. The primary advantage in this context is indeed their ability to amplify the light within the home, thereby enhancing visibility and creating a more inviting atmosphere.
