Pillar 18 in Enclosure D, one of the central paired pillars, has arms carved in low relief along the sides of the shaft, bent at the elbows, with hands that meet in the front of the shaft with carved fingers and details.

A belt-like element is carved across the front of the shaft at waist height, and what appear to be garments — clothing-like details suggesting a folded fabric or a robe — are carved below the belt.

The T-bar at the top, rather than being read as a simple architectural feature, can be interpreted as representing the head and shoulders of a human figure — the horizontal bar suggesting the outstretched arms or the broad shoulders of an upright body.

This anthropomorphic reading is not universally accepted in all its details, and scholars debate the extent to which specific features should be interpreted as representing human anatomy versus abstract geometric forms that happened to resemble human features.
