Roman art refers to the visual arts made in Ancient Rome and in the territories of the Roman Empire. Roman art includes architecture, painting, sculpture and mosaic work. Luxury objects in metal-work, gem engraving, ivory carvings, and glass, are sometimes considered in modern terms to be minor forms of Roman art, although this would not necessarily have been the case for contemporaries. Sculpture was perhaps considered as the highest form of art by Romans, but figure painting was also very highly regarded. The two forms have had very contrasting rates of survival, with a very large body of sculpture surviving from about the 1st century BC onwards, though very little from before, but very little painting at all remains, and probably nothing that a contemporary would have considered to be of the highest quality.
