Roman mosaics were influenced by southern Italy and Greece, developing sophisticated techniques over time. They were commonly found in places of worship, government buildings, and homes, depicting rulers, gods, and daily Roman life in colorful, detailed designs. Mosaics competed with paintings and were very durable, with colors that remained vibrant over time. Romans used materials like stone, glass, and ceramic cut into tesserae to create mosaic patterns and images that portrayed themes like the seasons and gods. The techniques and materials used evolved over the centuries, with mosaics reaching their golden age in the 4th century AD.
