This is the head of a Cycladic Idol. 

The Cycladic civilization of the Aegean sea flourished at about the same time as the early Egyptian and Mesopotamian civilizations (c. 3000-2000 B.C.) and is considered the forerunner of the first truly European civilization- Greece. The sculpture produced by the artisans of the Cyclades islands was very unique compared to the art being produced by the Egyptians and Mesopotamians. These sculptures, commonly called Cycladic idols, were often used as grave offerings, which points to the obvious role of religion in society. All of the idols were made of Parian marble. Probably the most striking characteristic of Cycladic sculpture is its geometric, two-dimensional nature, which has a strangely modern familiarity. However, while modern art attempts to estrange itself from artistic complexity, the Cycladic artists made obvious attempts to represent the human form. Therefore, Cycladic sculpture can safely be called the first truly great sculpture in Greece.
