The word for "flower" being nic in Maya and xochitl (pronounced hoochitl) in Nahuatl, it must be admitted that the symbol of a vase with a flower seems to afford an instance of a bilingual rebus, as the Maya hooch is identical in sound to the Nahuatl xoch-itl. Even without this, however, the meaning of the tree and serpent, the bird, the vase, the quadripartite flower, and the head, would have been generally and equally intelligible to native tribes, being familiar symbols constantly employed in metaphorical speech.
Mr. Maudslay has pointed out and illustrated in his work (Biologia, pl. 92, pt. X) that the side branches of the "cross" simulate bearded serpents' heads, whilst their recurved upper jaws are covered with what resemble buds of flowers, seeds or beads. The Palenque "cross" is indeed characterized by being profusely decorated with "bead or seed-like ornaments and appendages" some of which resemble beads or seeds, figured in some instances, like those on the Copan swastika, the meaning of which seems supplied by the previously cited Zuñi text. It does not appear to be a mere matter of chance that the following Maya words, culled from the dictionaries, are so closely connected: yax-ché=a sort of ceiba tree, the emblem of celestial life of the Mayas; yax-chumil and yax-pa-ibe=adjectives primitive, original; adverb firstly, at the beginning; yaxil, verb=to make something new, to commence, begin; yaxil-tun=bead or pearl; yax-mehen-tzil=eldest son.
According to this incontrovertible evidence we find that the sacred tree of life of the Mayas was designated by the word yax, signifying first, original, new, etc.; that the same root enters into the composition of the word for eldest son and finally for "bead." The latter curious agreement is accentuated by the well-known fact that the Mexicans employed in metaphorical speech the word cuzcatl=bead made of some precious stone, to designate "father, mother, lord, captain, governor; those who are like a sheltering tree to the people" (Olmos, cap. VIII). A term of particular endearment for a son was "gold-bead" (teocuitla-cuzcatl). Olmos moreover records no less than eight metaphorical designations for a "Tree, or first father, origin of generation, lord or governor," and appellations for twenty-nine "Relatives who issue from one stem or trunk."
