What identification does 'tesserae' refer to in art?

The term 'tesserae' specifically refers to the small, often varied pieces that are used to create mosaics. Mosaics involve assembling these individual tesserae, which can be made from various materials such as glass, stone, or ceramics, to form intricate patterns and images. This practice dates back to ancient art forms, where artists meticulously placed these small fragments together to convey elaborate scenes or designs. Unique tesserae contribute not just to the visual appeal of the mosaic but also to its texture and depth, playing a crucial role in the overall artistry of the work. Therefore, recognizing tesserae as the building blocks of mosaics is essential in understanding this specific art form and its historical significance.
