Human sacrifices also took place at certain points in the mountains where artificial ponds were consecrated to Tlaloc. Cemeteries were situated in their vicinity, and offerings to the god interred near the burial-place of the bodies of the victims slain in his service. His statue was placed on the highest mountain of Tezcuco, and an old writer mentions that five or six young children were annually offered to the god at various points, their hearts torn out, and their remains interred. The mountains Popocatepetl and Teocuinani were regarded as his special high places, and on the heights of the latter was built his temple, in which stood his image carved in green stone. The Nahua believed that the constant production of food and rain induced a condition of senility in those deities whose duty it was to provide them. This they attempted to stave off, fearing that if they failed in so doing the gods would perish. They afforded them, accordingly, a period of rest and recuperation, and once in eight years a festival called the Atamalqualiztli (Fast of Porridge-balls and Water) was held, during which every one in the Nahua community returned for the time being to the conditions of savage life. Dressed in costumes representing all forms of animal and bird life, and mimicking the sounds made by the various creatures they typified, the people danced round the _teocalli_ of Tlaloc for the purpose of diverting and entertaining him after his labours in producing the fertilising rains of the past eight years. A lake was filled with water-snakes and frogs, and into this the people plunged, catching the reptiles in their mouths and devouring them alive. The only grain food which might be partaken during this season of rest was thin water-porridge of maize. Should one of the more prosperous peasants or yeomen deem a rainfall necessary to the growth of his crops, or should he fear a drought, he sought out one of the professional makers of dough or paste idols, whom he desired to mould one of Tlaloc. To this image offerings of maize-porridge and pulque were made. Throughout the night the farmer and his neighbours danced, shrieking and howling round the figure for the purpose of rousing Tlaloc from his droughtbringing slumbers. Next day was spent in quaffing huge libations of pulque, and in much-needed rest from the exertions of the previous night. In Tlaloc it is easy to trace resemblances to a mythological conception widely prevalent among the indigenous American peoples. He is similar to such deities as the Hurakan of the Kiche of Guatemala, the Pillan of the aborigines of Chile, and Con, the thunder-god of the Collao of Peru. Only his thunderous powers are not so apparent as his rain-making abilities, and in this he differs somewhat from the gods alluded to.
