Bonampak's king had his heir presented on the painted walls of his temple, and the heir never ruled

Bonampak, about 30 km south of Yaxchilan, was its dependency. Structure 1 at Bonampak has three rooms covered with murals. INAH says the ruler Chan Muwan II took power in 776 and governed until about 800. In Room 1 an attendant holds up a small child, possibly his first son, before the court, with dancers and musicians. The child was to succeed him. Room 2 shows a battle in which Chan Muwan II and his brother-in-law, the king of Yaxchilan, fight usurpers at Bonampak; captives are tortured and later sacrificed. Room 3 shows the lords performing self-sacrifice to complete the rites begun with the heir's presentation. INAH says the heir never took power, possibly because drought and crop failure led to war and abandonment. Wikipedia names the heir as Chooj and says Bonampak collapsed with Yaxchilan in the 9th century^†. Outsiders first saw the murals in 1946, guided by Lacandon Maya. A 1996 Yale project documented them.
