The ceremonial presentation of single leaves of the same kinds as those represented on the trees, as in fig. 53, no. 6, proves that underlying these picture-writings there is far more meaning than has heretofore been suspected or recognized. It is not possible for me to present here all the material I have collected on this subject which will be set forth in a future monograph. I will, however, direct attention to the peculiar treatment in fig. 53, no. 1, of the tree trunk which is enlarged and forms a quadriform figure. In no. 4, the trunk enlarges to the shape of a head; in no. 2 the tree grows from a human head and two young shoots issue from each side of the trunk, seemingly indicating a fresh growth in tribal life. In no. 5, we have an example of a human figure lying at the base of a tree and a fifth leaf growing in the centre of the treetop. Directing attention to the evident care taken in representing an equal number of branches pointing upwards and downwards I would cite here an extremely interesting representation of a tree in the Borgian Codex. In this case the trunk issues from a conventionally drawn heart, figured in the centre of the symbol for sky or heaven. As the Nahuatl for heart is yul-lotl, from the verb yuli=to live, to resuscitate, the idea is distinctly conveyed that the tree was that of life=yuli and proceeded from the celestial centre of life, Polaris or the Heart of Heaven, a native title for the Supreme Being.(47) In the Telleriano-Remensis MS., a “tree of Paradise,” so termed in the text, is figured, and there are, in other Codices, various examples of trees encircled with serpents, where it is obvious that this combination was made in order to express, phonetically, that a celestial tree was intended, the word kan=serpent, being made to express kaan=heaven. A celestial tree, situated at the pole and bearing in some cases seven and in others five blossoms, was frequently depicted and its symbolism is obvious. In my commentary on the Hispano-Mexican MS. “The Lyfe of the Indians,” the “Gods,” “Five Flowers,” and “Seven Flowers,” will be treated in detail. From Sahagun and Olmos we learn that the Mexicans employed the image of a tree, metaphorically, to signify a lord, governor, progenitor, first ancestor. Relations are designated as “issuing from one trunk.” A branch is literally termed “the arm of the tree,” kab-ché. Two kinds of trees, the Puchutl and Aueuetl, signified, metaphorically, “a father, mother, lord, captain or governor who were, or are, like shade-giving, sheltering trees” (Olmos).
