Briefly summarizing the foregoing data, we find it proven that, deeply impressed with the wonderful renewal of life in nature, the ancient Mexicans rendered periodical thanksgiving for this in its various forms. The budding tree, the young shoots of the maize, all seedlings, the broken egg-shells from which the young chickens had emerged, were adopted as emblems of the renewal of life. The child was likewise looked upon as the renewal of the human race and every four years a thanksgiving festival “of renovation” was solemnized in which children took a special part. In my work on the Calendar system I shall show how far this festival “of new birth” coincided with astronomical phenomena. From Landa we learn that in the Maya months “Chen or Yax,” on a day designated by the priest, a festival was celebrated named Ocna: “the renovation of the temple in honour of the Chacs, the gods of the maize-fields.” This was held each year ... all idols and incense-burners were renewed and if necessary the building was rebuilt or renovated and, “in commemoration of this, an inscription in the native characters was fixed to the walls.”

Referring to other chapters of Landa's work we find that, as in Mexico, the Yucatec children received a “child's name” at birth which was changed when, having accomplished the third year, they were “reborn” and received a new name, i. e. the combined name of their father and mother. On attaining puberty they obtained an individual name which they preserved during life-time. A knowledge of the social organization of these people enables one to grasp the full importance and significance of these changes of name, which were accompanied by ritual observances and betokened the enrolment of the children into their respective classes and sub-classes and a consequent reorganization of certain departments of the State. It appears that in ancient times the ceremonial of the “new birth,” or re-naming of the children, took place every four years, simultaneously with the thanksgiving feast for the “continuation of the human race.”

A careful analysis of native words and metaphors tends to show, moreover, that the children born within each four-year-period were collectively regarded as “a fresh growth upon the tribal tree.” In [pg 243] Mexico the word for leaf=atlapalli, was employed as a metaphor for the lower class, whilst in Peru the male and female descendants of the Incas were represented by gold and silver fruits upon the trees of their male and female ancestry. The collection of such scattered scraps of testimony enables us to reconstruct the drift of native thought and realize that the registration of individuals was associated with the conception of a tribal tree bearing four branches and covered with blossoms, fruits and leaves which faded and fell but were replaced by fresh growths.

We learn from Duran that so careful a record was kept of the population, by the Mexican priesthood, “that not even a newborn babe could escape detection.” The reason for this strict vigilance is clear, for the welfare of the community and the harmonious working of the complex machinery of state depended upon the constant renewal of vacancies caused by deaths in each department of industry and government.

After this excursion into the realm of native thought let us now return to the Palenque tablets, placed in detached temples which approximately face the four cardinal points. On the tablet of the “Temple of the Cross” we have a tribal tree with symbols of the Middle and of the Four Quarters and of duality. A priest with a flower on his head presents a diminutive human figure to the totemic bird perched on the tree. Another, with a leafy branch on his head-dress, holds a conventional sceptre simulating a young growing shoot of maize. Behind each figure are rows of glyphs and in the upper corner to the left of the spectator is the septenary series headed by the initial-sign.

In the “Temple of Cross II” we have a variant of the identical representation in which the maize plant and the sea shell are prominent. If I may hazard a suggestion of the meaning of these two tablets, I should say that they appear to be tribal registers most probably relating to the increase and decrease of the male and female population in all divisions and classes, during a fixed period of time. Both seem to commemorate the “renovation” or “new growth” of the tribal tree in a mode which would have been as intelligible to a Mexican, for instance, as to a Maya. The fact that the “Temple of the Sun” and that of the “Inscriptions” obviously held analogous registers, points to the alternative possibilities (1) that each temple was destined to preserve [pg 244] the register of the population and social organization, etc., of one of the four quarters of the capital and state, according to years; (2) that the trees in the “Cross temples” figured the male and female lineages of the ruling caste, whilst the tablet in the “Temple of the Sun” recorded the numbers of conquered people reduced to slavery and the “Temple of Inscriptions” preserved the register of female children or of vassals; (3) that each of the four temples preserved a complete register of the entire state and had been erected consecutively at the conclusion or beginning of eras, the difference observable in the central motif conveying the salient feature or event marking each special epoch and recording, according to years, the organization of the state during its course.

In the face of this possibility as well as the probability that each glyph was painted and implied a year, it is interesting to note that, including the initial glyph, the “Tablet of the Cross” exhibits 108 glyphs on the side to the left and 124 on the side to the right of the spectator=a total of 232; the “Tablet of the Cross II” exhibits 76 to the left and 83 to the right=159; and that in the “Temple of the Sun,” 70 to the left, 159 to the right and 12 in the middle=241. The “Temple of Inscriptions” exhibits the initial series (see Maudslay, Biologia, pt. x, pl. 82) and entire walls covered with glyphs, some of which, as on the tablets enumerated above, are accompanied by numerals whilst others are not.

In a future publication I shall submit illustrations of these monuments with the ripened results of my investigations concerning them. For my present purpose it suffices to have produced substantial proofs that the ancient dwellers in Palenque employed the same metaphors, the same cursive method of registration and held the same fundamental principles of organization that have been shown to underlie the civilizations of Peru, Guatemala, Yucatan, and Mexico and still survive amongst the Zuñis and more northern tribes. It is obvious that, at Palenque and the neighboring Menché and Ixkun, an integral civilization, based on these principles, had existed for an incalculable length of time. Strangely enough it seems to form so close a link between Maya and Mexican culture that it almost seems justifiable to surmise that both Maya and Nahuatl languages were spoken in these ancient ruined cities.

Proceeding mentally northwards we will not linger at the ruins of Mitla, the name of which seems to indicate that it had lain to [pg 245] the north of a great ancient centre of government, since Mictlan in Nahuatl and Mitnal in Maya both designate the region of the underworld and the north.

Reaching the ultimate stage of our mental exploration of the American Continent we now transport ourselves to the Valley of Mexico and, on the site of the ancient capital of Montezuma and his coadjutor, face the three great monolithic monuments which are popularly known as the Calendar Stone, the Stone of Tizoc and Huitzilopochtli. In 1886, at the Buffalo Meeting of the American Association for the Advancement of Science, I presented a “Preliminary Note of an Analysis of the Mexican Codices and Graven Inscriptions,” in which the opinion was advanced that the “Calendar Stone” was identical with the “circular elaborately carved tablets which, according to Padre Duran, were erected in each market-place in ancient Mexico, and were held in great veneration. They were frequently consulted and by them the market-days were regulated.”
