Mosaic is an old painting technique that involves the use of colorful and shaped cubes made of stone, glass or glazed ceramics, which are then arranged into various patterns and images. Mosaic is the most popular painting technique in Roman art. This technique was used to decorate private and public buildings, such as thermal baths, public buildings, villas and houses. With the rapid development of cities, the interest in mosaics rises. Therefore, the mosaic becomes the most important part of the architectural decoration. Numerous floor mosaics were found in Roman villas and early Christian basilicas in the area of Colonia Iulia Pola and its wider area along with the empire of villas from the area of the Veriga bay from the 1st century BC to the 5th century AD. Furthermore, there are three types of Roman villas in which mosaics were found: villa rustica (a villa outside the city where mainly servants live), villa urbana (a villa that is part of a larger complex, built in the urban centers) and villa maritima (a villa on the seashore with the dominant appearance). One of the most famous floor mosaics, from the Roman villa urbana, is the Punishment of Dirka mosaic. Furthermore, the mosaic from Castropola Street in Pula and the mosaic in the chapel of St. John in the monastery of St. Francis in Pula were also found in the remains of the Roman villa urbana. On the other hand, the mosaic in the peristyle villa in Pomer and the mosaic from Valbandon near Pula were a part of a villa rustica. Furthermore, among the remains of villa maritima these mosaics were found: mosaic from Vižula near Medulin, mosaic from Great Brijun in Veriga bay, mosaic from a villa near Barbariga and mosaic from Dragonera near Peroj. The following mosaics were also found in Colonia Iulia Pola: a mosaic near Dante’s Square in Pula, a Salus mosaic from the quarter of St. Teodora in Pula, a mosaic from Betiga - St. Andrew near Barbariga, a mosaic from the Nezakcij near Pula, and a mosaic from the Basilica of St. Mary Formoza from Pula. The last three mosaics were floor mosaics in early Christian basilicas
