"The hieroglyphic text may be found on two panels on each side. The inscription on the east side begins at the southern end of the lower panel, recording the dedicatory date 18.104.22.168.0 using head-variant numerals. A series of dates are counted from this on the west side. One of these, 22.214.171.124.0 (784 A.D.), appears to refer to the death of Cauac Sky. Another at 126.96.36.199.18 9 Eznab 1 Kanklin, some 78 days later, probably records the accession of his successor, a ruler named Sky Xul. Thus, Monument 7 is seemingly Cauac Sky's death or funerary monument, as well as a commemoration of the inauguration of his successor (and son?). The fact that Monument 7 is facing the center of Structure 1A-3 may be an indication that Cauac Sky's tomb lies within or beneath this structure. However, following this clue in 1977, the Quirigua Project trenched and tunneled through the north-south axis of Structure 1A-3 without turning up a single sign of a tomb. Cauac Sky's final resting place remains unlocated, although it may still lie within an unexcavated portion of Structure 1A-3 or, perhaps more likely, within the northern Plaza Platform itself."
