This article presents the results of a contextual analysis of graffiti found in Substructure II-B at the Maya city of Calakmul. The final use of this space was for the burial of an important Kanu’l lord, whose identity—as shown by a recent analysis of the Long Count date inscribed as part of the graffiti—seems to be that of Yukno’m Ch’een II. My analysis of the frequency of appearance of different categories of graffiti within the structure, compared to the frequency of the same categories within the total set of graffiti recorded in the Maya area, suggests that the main objective of its creators was the ritual reconditioning of this space: they wished to make it more suitable for the entombment of the ruler, through its aesthetic modification, in what constitutes an example of placemaking. The inclusion of images of deities associated with death, rebirth, abundance, and kingship reconfigured the room and transformed it into a sacred space in which the burial process could be properly carried out. Analyzing the graffiti in the context in which they are located allows us to better understand the intentionality of its creators.
