The upper surface of this exhibits the same division into eight parts, marked by four large and four smaller rays, pointing to the quarters and half-quarters. Observation shows that of the sixteen localities four were assigned to each quarter and it is evident that the monument determined the time and the order in which the tribute for each was paid and collected at the capital. The one-footed man again graphically symbolizes axial rotation and conveys the idea of a central ruler who in turn seizes and exerts control upon 4×4 tribal chiefs. The monument establishes, moreover, the interesting fact that amongst the subjugated communities were two gynocracies, represented by women who, instead of spear-throwers, present their weaving shuttle to the victor. We shall next consider a monument whose uncouth and ugly form embodies a deep and nobly planned conception of the “divine twin,” or “divine Four,” that so completely dominated the minds of the native philosophers. Let us now carefully examine the monolith now preserved in the National Museum of Mexico (fig. 57). Leon y Gama, having observed that what appeared to be the foundation of the statue was carved and that massive projections existed under its so-called arms, logically concluded that the original design had been to support the figure from the sides, so that its base was lifted from the ground and the figure upon it exposed to view from underneath. His inference is borne out by the carving on the base which belongs to the same category as the image of Mictlan-tecuhtli, and represents a semi-human body, of quadriform shape soaring downward.
