Bracket container for burning incense

This cylinder ceramic hand-shaped would have supported a bowl for burning incense in ceremonial rituals.
On the front it shows a standing figure with a ground loop between the eyes, which are believed to be associated with the mayan god of the sun. The figure (along with two other companions, to the sides) placed over the shell of a turtle from which emerges a human head, probably a representation of a maya deity of the underworld.
Turtle shells are considered as metaphors for the land, its openings were seen as analogous to those of the caves. The combination of references of the sun and of the underworld suggests that the cylinder is a representation of the tree of life, with reasons alternative. The underworld, represented by the god in the turtle, the carapace, represented to the terrestrial world, and the God of the sun, representing the celestial world. On which incense is lit.
