"Temple I, the funerary shrine of Ah Cacau [now referred to as Jasaw Chan K'awil], was built after his death, probably under instructions he gave to his son and successor, Yax Kin Caan Chac [Yik'in Chan K'awil]. Ah Cacau's tomb was discovered underneath the shrine, north of the centerline of the pyramid.
On its summit is a three-room temple surmounted by a huge roof comb portraying the ruler seated on his throne; this temple undoubtedly served as his mortuary shrine. A carved wooden lintel inside the shrine depicts Ah Cacau seated before an immense jaguar-protector deity, and records his inauguration."
