LOCATION Found on the west side of the southern extension of Structure B-20.
CONDITION The shaft is unbroken, but the entire front of it, in the form of a layer perhaps 15 cm thick, has split off and disintegrated. The loss maybe attributed to natural causes, although purposeful mutilation in antiquity cannot be discounted. The back and sides are moderately well preserved; there have been some losses from the back by flaking, but some of the irregularity so caused occurred before the incised text was carved.
SHAPE Unsymmetrical, tapering toward base; canted top.
CARVED AREAS Sides carved in low relief, as the front may have been also. The back carries an incised hieroglyphic text.
PHOTOGRAPHS Graham, 1969.
DRAWINGS Graham, based on field drawings corrected by artificial light, and a photograph of the incised text emphasized by inking.
REMARKS Nearly vertical parallel lines, which show most clearly on the plain base and over the three rows of glyphs next above it, may have originated when the shaft was dragged from the quarry to its place of erection. The same may be true of the thin laminae that must have split off before the text was incised, since the finish of the back suggests that at one time it had been smoothly dressed all over.
