"This piece, found as a result of explorations carried out between 1991 and 1994, comes from the Temple of the Foliated Cross. The use of composite incense burners in the Maya area has a long tradition that goes back to the Late Preclassic period. The most notable characteristics of these objects are the hollow, cylindrical pedestals with two flanges at each side. These traits are preserved until the Late Classic, a period when decoration becomes more complex.
The examples recovered in the Group of the Crosses at Palenque are characterized by having masks superimposed on the central face as if a headdress; it also includes birds of different types and figurines of deities at the top. This example displays the face of GIII of the Palenque Triad, a deity that personifies the underworld sun. The bird holds the head of the Maize God in his beak, the same deity who is seen with his head replacing an ear of corn. At the peak stands the image of GII, kawil, a deity related to fertility and one of the most important symbols of the ruling nobility."
