The Aztecs excelled in carving tightly coiled serpent sculptures from fine-grained stone. In such sculptures, the tall stacked coils are carefully cross-hatched for the scales, and the rattle tail is tucked at the base. Many of the sculptures have additional symbolic icons carved on their bases. On the flat bottom of this sculpture is a realistic long-eared rabbit image next to a dotted circle representing the numeral one. Rabbit is the eighth of the twenty Aztec day signs.
