(a) Nine “lords” or patron gods of the night-hours. (b) Thirteen “lords” of the day-hours. THE TONALAMATL AND THE SOLAR CALENDAR It will be asked: “In what manner did the soothsayers reconcile the days of the tonalamatl with those of the calendar?” By what method did they find such and such a day in the tonalamatl in the tonalpohualli, or solar calendar? How was the one adjusted to the other? In order to reply clearly to this question, it will first be necessary to describe briefly the nature of the Mexican solar calendar or time-count proper. The Mexican solar year consisted of 365 days, divided into 18 periods of 20 days each, called cempohualli, or “months,” and one period of 5 days, known as nemontemi, or “useless” or “unlucky” days. The Cempohualli.—The names of the 18 cempohualli, or “months,” were [343]: Month Seasonal Character Presiding God Atlacahualco Ceasing of rain Tlaloquê Tlacaxipeuliztli Seed time Xipe Tozoztontli Rain desired Tlaloquê Ueitozoztli Worship of new maize Chicomecoatl Toxcatl Commencement of rainy Uitzilopochtli and season Tezcatlipocâ Etzalqualiztli Rain desired Tlaloc Tecuilhuitontli Rain desired Uixtociuatl Ueitecuilhuitl Adoration of the ripening Xilonen maize Tlaxochimaco First-flowering Uitzilopochtli Xocohuetzi Heat for ripening Xiuhtecutli Ochpaniztli Refreshment of the Tlazolteotl Earth-mother Teotleco Return of the gods from Tezcatlipocâ rest Tepeilhuitl Rain Tlaloc Quecholli Rain Mixcoatl Panquetzaliztli Winter solstice Uitzilopochtli Atemoztli Rain Tlaloquê Tititl The season of sereness Ilamatecutli Izcalli Toasting of the corn supply Xiuhtecutli Eight out of eighteen of these festivals are thus connected with the appeal for rain, or the celebration of its appearance. The remainder celebrate the growth of the maize in its various stages, rejoice at the appearance of these blossoms which were so dear to the Mexican heart, are held in honour of the Earth-mother, or mark the solstices.
