A mosaic is an art form that involves creating images or patterns by assembling small pieces of materials, such as glass, stone, or ceramic tiles. These pieces, known as tesserae, are arranged in a way that forms a cohesive design when viewed from a distance. Mosaics can be found in various cultures and historical periods, often used to decorate floors, walls, and ceilings in buildings. Mosaics can vary in size and complexity, ranging from small decorative items to large-scale installations. They are commonly associated with ancient civilizations, such as the Romans and Greeks, who used them in public spaces and religious sites. Today, mosaics continue to be a popular medium for artists and designers, often seen in contemporary art and architecture.
