Tesserae are small pieces of material, often made of glass, stone, or ceramic, used in the art of mosaics. These tiny fragments are arranged to create intricate designs and images, commonly found in ancient Roman and Greek architecture. Mosaics made with tesserae can be seen in floors, walls, and ceilings, showcasing vibrant colors and detailed patterns. The technique of using tesserae dates back thousands of years and has been used in various cultures around the world. Artists select and place each piece carefully to form a cohesive artwork, making tesserae an essential element in the creation of decorative surfaces in both historical and contemporary art.
