This beautifully sculpted animal effigy vessel was a very important type of commercial ware during the Toltec civilization. It was produced at only one place, on the Pacific slope of the Ancient region known as Soconusco. Such sculptural vessel from this region is called plumbate ware and the process which it was made seems to have been a secret. The plumbate ware was highly valued and was traded to far regions such as Panama. Although the sculpted vessel shows features created with incision lines on the beautiful dark-brown surface, the vessel is known for its exceptional hardness--it can be scarcely scratched with steel. This effigy vessel is a superb example of the Toltec culture since most of its effigy vessels only depict gods, men, and animals.
