Ancient art refers to the many types of art produced by the advanced cultures of ancient societies with some form of writing, such as those of ancient China, India, Mesopotamia, Persia, Palestine, Egypt, Greece and Rome. The art of pre-literate societies is normally referred to as Prehistoric art and is not covered here. Although some Pre-Columbian cultures developed writing during the centuries before the arrival of Europeans, on grounds of dating these are covered at Pre-Columbian art, and articles such as Maya art and Aztec art. Olmec art is mentioned below.
