An unusual Maya stela in the St. Louis Art Museum has a number of distinguishing characteristics: (1) The cylindrical shape is comparatively rare for a free-standing Maya monument. (2) Thegtyphic inscription contains four previously unnoted glyph groups. (3) The inscription includes a rare glyph group of which only a very few examples are known. (4) The shape of the glyphs and the placement of the numbers seem to be governed by aesthetic considerations, although the variations of the tun glyph may have semantic implications.
