More sculptures on the upper level of the large pyramid at Ek Balam (Black Jaguar), Yucatan. Teeth, eyes, and open mouths serving as doors to the Underworld are recurrent themes in Maya iconography. Made of fine limestone stucco in, probably, the 8th century CE, and well conserved by the builders who surrounded it with sand when its useful life was at an end. Note the skull at the lower corner. The palm thatch roof and supports were erected by archaeologists to help with modern preservation. For more on Ek Balam, see preceding frames.
