Herbert Joseph Spinden, Ancient Civilizations of Mexico and Central America
“ The curious objects of ceramic art that we have found deeply buried under the débris of higher civilizations in the Valley of Mexico can be traced far and wide. They are encountered, for the most part, in arid and open country, and since we have every reason to believe that the earliest agriculture was developed under irrigation, it is but natural to find the use of agriculture spreading first into other arid regions. And if there was an association between the fertility of Mother-Earth and little fetishes representing women then these fetishes would spread as part of the agricultural complex. ”
