There is a temptation to imagine that possibly after the adoption of two distinct cults of which the second pyramid seems to furnish incontrovertible proof, a further divergence ensued resulting in the ultimate abandonment of the capital by the votaries of the Sun, the male principle and the Above. As the native civilizations were based on such a plan that dissension and disorganization inevitably led to utter downfall and ruin, it is easy to see that a gynocracy and the cult of the earth and underworld should gradually become extinct. At the zenith of its power, however, it may safely be inferred, that Teotihuacan was a great centre where astronomical observation and agriculture flourished, these being the natural outcome of the cult of mother-earth and the nocturnal heaven. Whilst all conjecture must necessarily be hypothetical, it is a comfort to reflect that, locked in the ruins themselves, lies guarded the past history of Teotihuacan, which was shrouded in a mist of uncertainty even at the time of the Conquest. The pyramids themselves, however, openly reveal the fact, that their builders possessed a knowledge of the great plan, and that, at some time, a single central pyramid not being sufficient, two, of unequal sizes, arose to bear lasting testimony not only of past greatness, but of long-forgotten rivalry and dissension. Finally, there is one thing certain, namely, that the building of the pyramids at Teotihuacan must have been preceded by an extremely long period during which the native ideas, of which they were the expression and image, had developed and taken definite shape. If Teotihuacan yields evidence of an advanced stage in the history of the intellectual development of the native race, it also marks the beginning of the disintegration of the state of which it was the central capital. On the other hand, at Cholula, also situated in the high plateau of Mexico, to the east of its present capital stands, in ruined solitary grandeur, the largest pyramid on the American continent, whose base is twice as large as that of the pyramid of Cheops in Egypt.
