One of the most intriguing ceramic wares of the northern Ecuadorian hi
ghlands is a distinctive, thin-walled pottery commonly known as Panzal
eo. Though widely dispersed throughout the northern highlands, it rare
ly, if ever, forms the sole or even primary element of archaeological
site assemblages in this region. The ubiquity of this ware has led to
considerable discussion about its nature and significance. The basic c
haracteristics of this ware are reviewed, along with the results of tw
o separate compositional analyses of Panzaleo sherds from the Guayllab
amba-El Quinche region of northern highland Ecuador and the Cosanga re
gion of the eastern montana. A comparative study of sherds from the tw
o different regions demonstrates a high degree of similarity in the pa
ste composition of pottery samples from the highlands and the eastern
montana. The mineralogy of the ware points to the eastern foothills of
the Andes as the probable locus of its production, suggesting the exi
stence of prehistoric relations of exchange between northern highland
and eastern lowland groups. Separate morphological and contextual anal
yses of Panzaleo pottery lead to several hypotheses regarding the sign
ificance of the ware that relate, in part, to its association with low
land cuisine and feasting ritual.
