What is the name of the small pieces used to create mosaics in ancient art?

Tesserae are the small, often square or rectangular pieces of material, such as stone, glass, or ceramics, that are used to create mosaics in ancient art. The use of tesserae allows artists to piece together intricate designs and scenes, resulting in visually striking artworks that were commonly found in Roman villas, public buildings, and baths. This technique was highly valued in ancient times, as it provided durability and a means to depict complex imagery in a decorative manner.

The term tessera comes from the Latin word for "small square," which is fitting given their shape. The art of mosaic-making was a significant craft in the ancient world, demonstrating both aesthetic beauty and technical skill. In contrast, the other options do not relate to the components used for mosaics; they refer to different aspects of ancient culture or terminology unrelated to the art of mosaic creation.
