Between 500 and 1000, successive waves of conquerors—Ostrogoths, Byzantines, Langobards, Franks, and Arabs—capture and recapture strategic cities in the Italian peninsula and Sicily and erect monuments to assert their legitimacy. Because of the many peoples active in the Italian peninsula, art of the period shows the influence of many different styles. The legacy of the Roman empire looms large; while many ancient buildings fall into disrepair, many Roman roads and bridges remain serviceable and monumental art is everywhere in evidence. Italian builders quarry Roman sites for precious marbles, and Italian painters and sculptors refashion motifs from Roman art.
