The earliest art by Greeks is generally excluded from "ancient Greek art", and instead known as Aegean art; this includes Cycladic art and the art of the Minoan and Mycenaean cultures from the Greek Bronze Age. The art of ancient Greece is usually divided stylistically into four periods: the Geometric, Archaic, Classical, and Hellenistic. The Geometric age is usually dated from about 1000 BC, although in reality little is known about art in Greece during the preceding 200 years, traditionally known as the Greek Dark Ages. The 7th century BC witnessed the slow development of the Archaic style as exemplified by the black-figure style of vase painting. Around 500 BC, shortly before the onset of the Persian Wars (480 BC to 448 BC), is usually taken as the dividing line between the Archaic and the Classical periods, and the reign of Alexander the Great (336 BC to 323 BC) is taken as separating the Classical from the Hellenistic periods. From some point in the 1st century BC onwards "Greco-Roman" is used, or more local terms for the Eastern Greek world.
