In my opinion it is impossible to study the above and supplementary data without realizing that the native race assigned its origin to a dual star-divinity, associated with the Tecpatl, the symbol for the North and for Fire. The peculiarity that the divinity is designated as Seven-flowers, and that there were seven tribes, indicates that the native idea was that each tribe came from one of the seven stars in Ursa Major or Minor. The Aztecs seem to have claimed for themselves the descent from the superior star, the central one, and to have thus justified or supported their ultimate establishment of a central government which ruled over the other six tribes. [Illustration.] Figure 26. The assumption that the native race claimed descent from the Ursa Major or Minor constellation is further supported by the fact that the shape of the mythical recurved mountain and the name Aztlan=land of light or brightness are simultaneously explained, as well as the number of caves and tribes. It does not seem to be a mere coincidence that in two totally different Codices (the Selden MS. p. 7, Kingsborough, vol. 1, and the B. N. MS., p. 70) a sacred dance is represented as executed by seven individuals who move around a central seated personage. In the latter MS. the seated figure wears a head-dress surmounted by flint knives and his face is painted _red_ the color assigned to the North. Moreover the dance is taking place before an image of Mictlan-Tecuhtli, the lord of the North, whose raiment is strewn with cross-symbols. Referring to other native dances we find that the most sacred of all dances was performed at the festival of the god of fire by priests only, who, smeared with black paint to typify darkness and night, carried two torches in each hand and first sat, then slowly moved, in a circle, around the “divine brazier,” and finally cast their torches into it (Duran II, p. 174). This, probably the most ancient of sacred dances, must have been extremely impressive and significative to those who witnessed it, at night-time, from the base of the pyramid and heard the distant solemn chant of the dancers. To watchers from afar, the fire and the lighted torches revolving around must have seemed like a great central star with other stars wheeling about it.
