So intricate! This is an Aztec deity?

the skull-face in the center is supposed to be Mictlantecuhtli, the "main" (if you could call it that) god of death and underworld (originally there's Tonatiuh the sun god in his place), the glyphs in the rectangles represent the previous eras or the days when these eras ended - the top right is "nahui ocelotl" (4 jaguar or jaguar sun) of the first era, the top left is "nahui ehecatl" (4 winds or wind sun) of the second era
