An interesting indication that the entire dominion of Mexico was also divided into four equal quarters, the rule administration of which was attended to by four lords, inhabiting towns situated within a comparatively short distance from the capital, is furnished by Bernal Diaz (_op. cit._ p. 65). He relates that the four lords who supported Montezuma when he walked in state to meet Cortés were the lords of Texcoco, Iztapalapa, Tacuba and Coyoacan. These towns, which were minor centres of government, were respectively situated at unequal distances to the northeast, southeast, northwest and southwest of the capital.
These facts and the knowledge that "all lords, in life, represented a god" justify the inference that, just as Montezuma represented the central power of the Above or Heaven, the four lords who accompanied him were the personified rulers of the four quarters, associated with the elements. In ancient Mexico and Maya records the gods of the four quarters, also named "the four principal and most ancient Gods" are designated as "the sustainers of the Heaven" and it cannot be denied that, on the solemn occasion described, the four lords actually fulfilled the symbolical office of supporting Montezuma, the personification of the Heaven. This striking illustration is but one of a number I could cite in proof of the deeply ingrained mental habit of the native sages to introduce, into every detail of their life, the symbolism of the Centre, the Above and Below and the Four Quarters. I shall but mention here that it can be proven how, in their respective cities the lords of the cardinal points were central rulers who, in turn, directed the administration of the government by means of four dignitaries. Each of these was also the embodiment of a divine attribute or principle, "All noblemen did represent idols and carried the name of one" (Acosta, Naturall and Morall Historie, lib. 5, p. 349).
Each wore a special kind of symbolical costume and was the ruler or "advocate," as he is termed, of a distinct class of people. "For to each kind or class of persons they gave a Teotl [=God or Lord] as an advocate. When a person died and was about to be buried, they clothed him with the diverse Insignia of the god to whom he belonged" (Mendieta lib. II, chap. 40). It being established that each of the four year-symbols, acatl, tecpatl, calli and tochtli, ruled four minor symbols, it seems evident that, just as the four lords of the cardinal-points would correspond to the above symbols, each of the minor lords and the category of people they represented would also be associated with the minor symbols. The obvious result of this classification would be the division of the entire population of the commonwealth into 4×5=20 categories of people, grouped under twenty local and four central governments, whose representatives in turn were under the rule of the supreme central dual powers. Having thus sketched, in a brief and preliminary way, the expansion of the idea of dividing all things into four parts, the bud of which was the swastika, let us examine the Mexican application of the idea of duality, pausing first to review the data relating to the Cihuacoatl, the personification of the Earth, the Below and the coadjutor of Montezuma.
