en Heads Circle/Up and Down, 1990, is a series of wax-cast heads, separated into groups of two. In the work, Nauman sets up an imaginary conversation, or philosopher’s circle, and in reference to Johns, he uses wax fragments of bodies to form this circuit of communication. However, Nauman’s intercourse has a rough, makeshift quality and it is difficult to envision the heads in any sort of coherent connection; they hang from the ceiling on clumsy wire, some right side up and others upside down, they seem incapable of looking each other in the eye, and they have wax pouring from their mouths. As the viewer wanders through this circle, the impression is that the human capacity for communication has been somehow frustrated or thwarted.
