The earliest recorded place of worship of this deity is that spoken of by Clavigero [275] in one of the few enlightening passages which he permits himself, as follows: “The native historians relate, that the Acolhuas having arrived in that country in the time of Xolotl, the first Chichimecan king, found at the top of the mountain of Tlaloc, an image of that god, made of a white and very light stone, in the shape of a man sitting upon a square stone, with a vessel before him, in which was some elastic gum, and a variety of seeds. This was their yearly offering by way of rendering up their thanks, after having had a favourable harvest. That image was reckoned the oldest in the country; for it had been placed upon that hill by the ancient Toltecas and remained till the end of the XVth or beginning of the XVIth century, when Nezahualpilli, King of Acollhuacan, in order to gain the favour of his subjects, carried it away and placed another in its stead, of a very hard, black stone. The new image, however, being defaced by lightning, and the priests declaring it to be a punishment from heaven, the ancient statue was restored, and there continued to be preserved and worshipped, until the promulgation of the gospel, when it was thrown down and broken by order of the first Bishop of Mexico.” The principal seat of the worship of Tlaloc was the great temple of Uitzilopochtli at Mexico, which is fully described in the section which deals with that god. Sahagun speaks (Appendix to bk. ii) of a temple within the sacred precinct of Mexico which was especially dedicated to the Tlaloquê. This was the epcoatl (“pearl serpent”), so called, perhaps, from the circumstance that the victims immolated therein were known by the same name. It was in this place that the priests fasted and did penance for forty days before the feast in honour of their gods. The Mexico Calmecac was a school or junior monastery, where those who were destined to become priests of the god received their training. At the acatla yiacapan uei calpulli (“chief flowery hall”) the slaves intended for sacrifice to the god were assembled, and here their bodies were prepared for the horrid banquet which concluded his festival. PRIESTHOOD The Tlaloc Tlamacasque, the second in rank in the Mexican priesthood, stood at the head of the ministers of the god. The acolnauacatl acolmiztli (“he of the puma shoulder” or “dress”) made all arrangements for the festivals of the god, and kept the vestments worn by the king on these occasions. It is also clear from many passages that the priesthood of Tlaloc composed a large and considerable body. PRAYERS
