This marvelous stone sculpture of a skull is carved in a realistic manner, depicting especially powerful deep eye sockets and a full set of teeth. Such close resemblance to a real human skull has a strong visual and emotional impact on its viewers. In Ancient Meso-America, skulls were often used to suggest death and sacrifice, and this magnificently carved skull possibly represents the god of the underworld. The underworld was a place in afterlife through which all deceased have to go. Its nine layers are difficult to pass through and perhaps this god of the underworld was to oversee those who are traveling through those layers. In addition to the fine workmanship, the artist of the sculpture has carefully chosen the color of stone, light green with glimpses of whiteness that appears to be very dense. The color green often symbolizing life and virility, such choice of the color perhaps was to convey the idea of death and rebirth into the afterlife. Just like human bones that last for thousands of years, the dramatic, hard stone skull seems to defy the passage of time, wanting to last forever. This realistic depiction of a skull reminds people of the natural event of death and the eternal afterlife that awaits humanity.
