some of its pigment), although the glyphs on the upper right were weathered. Sometime in the 1960s, looters broke up the fallen monument so they would have an easier time smuggling it out of the site. The top portion is currently housed in the Museum of Fine Arts, Houston (MFAH), whereas the bottom half is in a private collection in Switzerland. Stela 9 had long been broken into thirds when it was discovered in 1899 by Maler. While these fragments had eroded slightly, the base was later found in situ by the University of Pennsylvania's University Museum. In the 1960s, looters carted off parts of the monument, namely a portion depicting a captive. Stela 10 is highly eroded, resulting in a loss of detail. In addition to this decay, the head ornament has presumably been lost. Stela 22 was dedicated on the East Group Plaza, located in front of Structure O-12, thereby "initiat[ing]" the East Group Plaza as a locus for sculpture and stelae. While previous stelae had faced other directions, Stela 22 faced northwest towards the site's acropolis, creating "a new axis of dialogue across the site." Stela 40 contains the depiction of the aforementioned woman dressed in Teotihuacano garb; it shows Itzam Kʼan Ahk II dispersing somethinghypothesized to be either blood or incenseinto a "psychoduct" (that is, "a vent leading into a subplaza tomb"). Simon and Grube argue that "the connection between the living and the dead is manifested [on this stela] as a 'knotted cord' or breath which travels down to enter the nose of the deceased". The female on the stela, denoted only by an "upside down vase" glyph, is likely Itzam Kʼan Ahk II's mother; Pitts argues that the monument "offers an interesting vignette of Itzam Kʼan Ahk II and his loyalty to a female ancestor, probably his mother." Pyramid O-13 Pyramid O-13 is the name given to the hypothesized mortuary temple of Kʼinich Yat Ahk II. According to Stephen Houston et al., it was nearly "twice as large" as any of Piedras Negras's previous structures. The pyramid was modified substantially following Itzam Kʼan Ahk II's demise: Kʼinich Yat Ahk II, for instance, reset the older Panel 2 and installed Panel 1 and the now-famous Panel 3. Megan O'Neil argues that these changes were made in order for the ruling ajaw to "engag[e] with the past". Given that the last known rulers of Piedras Negras
