This image of a dog was placed in a Roman home to warn intruders. What art form does it represent?

The image of a dog displayed in a Roman home represents mosaic art. Mosaic is a decorative art form that involves assembling small pieces of colored glass, stone, or other materials to create a picture or pattern. In ancient Rome, mosaics were frequently used to adorn floors and walls, often depicting scenes from mythology, daily life, or symbols meant to convey messages or warnings. In this case, the depiction of a dog served as a warning symbol, representing vigilance and protection against intruders. Such artistic representations not only beautified the home but also communicated cultural values and practical messages to visitors.
