Personal favorites from the Cycladic Antiquities include two parian marble figurines of musicians discovered in the same grave on Keros. The seated Harpist of Keros holds a stringed instrument (probably some kind of lyre or harp). The standing Flutist plays the double flute. Both are from the Early Cycladic Period, ca. 2800-2300 BCE.
From the National Archaeological Museum in Athens exhibition description:
Figurine of flutist, of parian marble.
The musician plays the double flute standing firmly on the ground. A three-dimensional expansion in space is apparent, placing it, along with the other musician figurines, among the master pieces of cycladic sculpture. In cycladic society the role of musician may have been performed exclusively by its male members. All known figurines of musicians depict male figures.
