While it does not contain a date, and was apparently reset in Structure 22 by the Late Classic king Bird Jaguar IV (Proskouriakoff 1964: 182), it can be palaeographically dated to the late 5th or early 6th-century.
This lintel is all-glyphic, containing 20 glyph blocks. Unfortunately, there are clear signs that the lintel was once part of a much longer narrative including the fragmentary Lintel 19 and perhaps other lintels, now lost. This, coupled with the difficult early text, make the narrative substantially less clear than one would like. At present, all that can be said with confidence is that the first half of the lintel seems to provide a list of youthful lords who stand in some unclear relationship of subordination with a higher-ranking lord named towards the end of the text.
