The mosaic is a Byzantine art obtained through the use of fragments of materials born in Mesopotamia and exported to the world of antiquity during the period of Hellenistic and Roman domination. (The tiles) of different nature and color (stones, glass, shells), are decorated with gold and precious stones. The Byzantine works, or mosaics, date back to the 6th century AD.

A tile in mosaic art is a fragment of any material that is used for the composition of pictorial figures. The tesserae were called in Greek ̀αβακίσκοι (abakìskoi), quadrelli, from ̀άβαξ (àbax), tablet, while in Latin abaculi, tesserae, tessellae.
