They were created by little pieces of glass
Originally mosaics were made of pebbles of various natural colours. Later they were made of small pieces of stone, shells, ivory and other materials. Marble and limestone were also used. Later still, coloured and clear glass backed with metal foil was used. The Byzantines introduced gold leafs sandwiched between two flatter pieces of glass.
The small pieces were called tessera (plural tesserae).
There are two methods of making mosaics:
The direct method is used especially for small portable three dimensional objects, such as vases. The tesserae are glued directly on the object's surface.
The indirect method is used for large mosaics or repetitive patterns. The tesserae are applied face down of backing materials and then transferred to the floor or walls.
There is also the double indirect method. This is a modern technique.
It is cave canem.
mosaic
One of the most famous Roman mosaics is the Alexander Mosaic, which depicts the battle between Alexander the Great and Persian King Darius III. Another well-known mosaic is the Villa Romana del Casale mosaic, located in Sicily, Italy, which showcases intricate scenes of Roman life and mythology. The House of the Faun in Pompeii also contains notable mosaics, such as the Battle of Issus mosaic.
The Nile Mosaic of Palestrina is significant in ancient Roman art and culture because it showcases the Romans' fascination with Egyptian culture and their mastery of intricate mosaic techniques. It also reflects the Romans' appreciation for the natural world and their desire to depict exotic landscapes in their art. The mosaic provides valuable insights into the artistic tastes and influences of the Roman elite during the time period.
The floors in a Roman villa were generally mosaic or stone slabs. Depending on the preferences of the owner they could be mosaic scenes such as the famous Alexander mosaic or the one of a watchdog with the warning "beware of Dog", found at Pompeii. However most of the flooring mosaics were of geometrical designs.
