The Museum's collection of Greek and Roman art comprises more than seventeen thousand works ranging in date from the Neolithic period (ca. 4500 B.C.) to the time of the Roman emperor Constantine's conversion to Christianity in A.D. 312. The geographic regions represented are Greece and Italy, but not as delimited by modern political frontiers: much of Asia Minor on the periphery of Greece was settled by Greeks; Cyprus became increasingly Hellenized in the course of its long history; and Greek colonies were established around the Mediterranean basin and on the shores of the Black Sea. For Roman art, the geographical limits coincide with the expansion of the Roman Empire. The department also exhibits the pre-Greek art of Greece and the pre-Roman art of Italy, notably of the Etruscans.
