But the Mexican calendar is hard to deal with. Müller places the feasts of Huitzilopochtli in the middle of May, the middle of August, and the middle of December.* He combines his facts with a legend which made Huitzilopochtli to be the son of the goddess of vegetation. J. G. Müller's whole argument is learned and acute, but errs probably in attempting to extract a consecutive symbolical sense out of the chaos of myth. Thus he writes: "When the myth makes the god the son of the mother of plants, it divides his essence from that of his mother, and thus Huitzilopochtli, however closely akin to the plant world, is not the plant world itself ". This is to consider more curiously than the myth-makers. The name of the patron goddess of the flower-wearers in feasts was Coatlicue or Coatlan, which is also the name of the mother of Huitzilopochtli; its meaning is "serpent petticoated".** * Uramerik. Rel. v. p. 602. ** Sahagun, ii. 8 When Müller goes on to identify Huitzilopochtli with the bunch of feathers that fell into his mother's breast before his birth, and that again with the humming-bird, and that again with the honey-sucking bird as the "means of fructifying the plants," and, finally, with the _männliche befrwchtende Naturkraft_, we have left myth far behind, and are in a region of symbolism and abstract thought, where one conjecture is as good as another. The hypothesis is that men, feeling a sense of religious reverence for the germinal force in Nature, took the humming-bird for its emblem, and so evolved the myth of the birth of Huitzilopochtli, who at once fructifies and is born from the bosom of vernal Nature. It would be rash and wrong to deny that such ideas are mixed in the medley of myth. But, as a rule, the sacred animal (as the humming-bird) is sacred first in itself, probably as a totem or as a guide and protector, and the symbolical sense is a forced interpretation put later on the facts.* We can hardly go farther, with safety, than the recognition of mingled aspects and elements in Huitzilopochtli as the totem, the tribal god, the departmental war-god, and possibly he is the god of the year's progress and renewal. His legend and ritual are a conglomerate of all these things, a mass of ideas from many stages of culture. An abstract comparatively brief must suffice for the other Aztec deities.
