Opus sectile mosaics

Opus sectile was a type of flooring that used marble and stones of square, triangular and rhomboidal shapes that were generally larger than those of other mosaic techniques.
The pieces that made up the design were larger than the tiles and therefore required less precision in cutting; even the hardest types of rock were used for this technique.
The availability of several types of stone elements gave life to representations characterised by a strong polychromy.
