Thirteen years of painstaking research have only served to strengthen me in my interpretation of the "Sacrificial-stone." The frieze around it exhibits sixteen groups, each consisting of the repeated representation of a warrior characterized by having one foot only. In each case he is figured as seizing by the hair a different individual, who bows his head and offers the weapon he holds in his right hand to his victor. Amongst the sixteen subjugated personages are two women and above each are hieroglyphs expressing the names of well-known localities, some of which are mentioned in native chronicles as having been conquered in historical times by Mexican rulers.
In my account of the Plan of the Ancient City of Mexico, I shall illustrate these hieroglyphs, locate the places to which they refer and further discuss this monument. Meanwhile I shall but state that it undoubtedly belongs to the same category of monuments as the tablets in the "Temple of the Sun" at Palenque; the bas-relief at Ixkun and that in the house of the "Tennis-court" at Chichen-Itza where warriors in a procession render homage to a seated personage, by presenting their spear-throwers to him in precisely the same manner as shown on the Mexican Tribute-Stone.
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.
