The "calyx-shaped kylix" was one of the most elegent vessel forms made in marble in the Early Bronze Age Aegean. The walls of this vessel are so thin that the marble appears almost translucent. Such fine work attests to the exceptional skills of the craftsmen of the Cyclades in the 3rd millennium BC.
Chalices of this type were usually made of white marble, although we do know also examples in dark or veined qualities of the material. Several of them preserve traces of red pigment inside, and in some cases traces of deep blue or green.
