The second room at Bonampak contains one of the most famous paintings of the all Maya world, the Mural of the Battle. At the top, the whole scene is framed by a series of figures and symbols of star constellations within a cartouche and brown spots that probably represent wooden beams.
The scenes depicted on the east, south and west walls portray the bustle of battle, with Maya soldiers fighting, killing and capturing enemies. Room 2's battle scenes cover the entire walls, top to bottom, rather than divided into registers as is Room 1 or the northern wall of Room 2. At the center of the south wall, noble warriors surround the military chief, the ruler Chan Muwan, who is taking a captive.
The north wall portrays the aftermath of the battle, which scene takes place within the palace.
- Upper register: In the top level of the northern wall, the king stands at the centre with his lieutenants, two Yaxchilan representatives, the queen and other noblemen.They wear elegant headdresses, jaguar pelts and jade pectorals, which stand in high contrast with the barely naked captives at their feet, laying on the steps of the palace waiting for their fate.
- Lower register: This section of the north wall is probably the most famous. A number of captives are sitting or kneeling on the stairs. Many have been tortured: blood spills from their hands and body parts. One captive lays dead below the king, with the severed head of another captive at his feet. The bottom drawing shows a series of standing warriors, probably waiting for the final sacrifice of the surviving captives.
