"Both the north and the south sides of this monument are carved with double columns of glyphs. The Initial Series date on the northern face records the dedicatory date of 18.104.22.168.0 [800 A.D.] using bar and dot notation. Jade Sky is named in the text on the south side, followed by an apparent title and the Quirigua "emblem glyph." A reference to 16 hel indicates that this ruler was the 16th in the dynastic succession."
