tesserae

Tesserae are small, usually square or polygonal pieces used to create mosaics—artworks made by assembling many tiny tiles into intricate patterns or images. Traditionally made from materials like glass, stone, ceramic, or smalti, tesserae are carefully cut to fit together tightly. Artists arrange these pieces on a surface, such as walls or floors, to form detailed visuals or decorative designs. Their size and material choices influence the artwork’s texture, color, and durability, allowing for detailed and vibrant images that have been used in art and architecture for thousands of years.
