From the fabled site at Monte Alban, Oaxaca, southern Mexico. 5th-2nd century BC. 4 3/4" diameter, coil work with flared lip and surface polished by drying to "leather hard" then burnishing before firing. Mottled brown to near black finish resulting from its position in the kiln. Collected in the 1960s by a Detroit doctor with some surface adhesion from burial. As with other pre-Columbian cultures, it is believed that the Zapotec used human sacrifice in their religious rituals.
